the dangers of mobile phone battery

We have long been heard the importance of recycling used Dell latitude d500 battery ,however, few people know the dangers of mobile phone battery . According to statistics, the majority of users between one to two years to replace a cell phone, and a small number of users in less than a year's time replacement of a cell phone, and a considerable number of users to simultaneously use two or more mobile phone.

Some data indicate that a cell phone inside the Dell latitude d400 battery contains cadmium can contaminate 60,000 liters of water, which is equivalent to three Olympic standard swimming pool capacity. 1000 Waste Pollution in mobile phone batteries with a very small paper mills. Cadmium pollution belongs to heavy metal pollution, can not be degraded in nature, only to migrate. In other words, once the water or soil contamination, water or soil can not be self-purification of the leading role will be to eliminate pollution, while the body of heavy metals easily bio-accumulated. In addition to cadmium, chargers, lithium Dell latitude c840 battery inside of copper, aluminum, plastics, electrolytes, and other non-ferrous metals also causing serious environmental damage.

According to an interview with the University of fourth-graders, who are less than four years college, replacing the phone about 6. "Often to see the new phone will be out before the natural selection. Generally thrown into the trash(certaily including the battery for Dell latitude c810 battery ), and some very new phone will be passed the number of distant relatives in rural areas."

Young students is very representative on the handling of waste mobile phones andapple a1185 12" apple powerbook g4 battery . As the mobile phone battery recycling campaign is not in place, not only for their crimes against the people there is no clear understanding of the importance, while the handling of used batteries also have no idea. In the cities, a lot of public advocacy work done a lot of cases, the battery placement like this, with the pattern of recent years, the opening of the mobile phone market in rural areas, rural mobile phone users lack of knowledge on the battery ,it is even more worrying.

According to media reports, there are three flows about discarded cell phoneDell latitude d505 battery , chargers Generally,: The user readily thrown away, to second-hand mobile phone dealers recovery, sent to a special recycle bin. The second-hand mobile phone dealers of used batteries, chargers and other recycling a very low price.

  • Harm caused by a battery
  • Scrap mobile phone battery into the trash

Environment experts said, for the treatment of discarded cell phone cell, at present we can only hope that people will choose nickel-metal hydride batteries and lithium-ion batteries as cell phone batteries , on the one hand, while the other hand, focus on looking forward to an early date on the legislative control of the Dell latitude d510 battery polluted.

3G mobile phone battery market's crowded

With 3G networks in the accelerated process of global commercial, 3G users also appeared to grow substantially. Technically advanced, 3G business has a unique appeal, prompting users to more and more frequently use a variety of multimedia services. Short period of 10 years, only to have a Dell inspiron mini 9 battery phone call from the set of functions to develop into a variety of functions in one portable device. In the meantime, the development of mobile phone batteries followed the evolution of technology development.

3G era, a number of mobile phone battery manufacturers ( such as apple a1185 battery ,Dell inspiron mini 9n battery and so ) are introduced several new mobile phone battery, greatly's crowded trend, the author sums up what the current development of mobile phone battery showed three major features: high-capacity, long standby, environmental protection and safety.

High-capacity, long standby Dell latitude c500 battery : with business smartphone show exponential growth, from the GPS electronic navigation to the MP3 music player, and then to WIFI wireless Internet access and so on, endless variety of phone functions, the protection of mobile phone standby time becomes a kind of features basis. A normal capacity of mobile phone battery apparently can not meet their daily use, this time high-capacity, long standby mobile phone batteries mobile phone batteries on the market will become the mainstream.

Security: The term is now more than ever a period of time have been of concern to everyone. In the experienced shoddy mobile phone battery explosion, the consumer is more rational, integrated balance of consumer, the price is a measure of a product is no longer the only indicator, the same major mobile phoneDell latitude c510 battery manufacturers found a market sensitive to atmosphere, and launched safety explosion-proof business mobile phone batteries, and also covered by commercial insurance companies, merchants well-intentioned, but also to the user more of a security.

Green: economic and social unity, is a mature company which should do. More and more enterprises in improving production efficiency while also interested in social welfare. Mobile phone battery for Dell latitude c540 battery industry is also true that many large companies are committed to R & D and production of more green cell phone batteries, to reduce environmental pollution, to avoid the disposal of mobile phone batteries free of ecological damage. This point, fortunately saw the development and progress of society as a whole.

Mobile phone battery market's crowded, it will provide more varied choice. However, given the many cottage manufacturers to follow suit and profit-making, suggest that you purchase a time when mobile phone batteries purchased from the formal channels, such an optional mobile phone battery(take the Dell latitude c600 batteryfor example)has become more secure, secure.

How the temperature have impact on the notebook computer battery ?

When using mobile , the battery decided to notebook life, as the too high or too low a temperature will bring a variety of problems for laptop with a lithium-ion xps m1730 battery , in the non-normal temperatures,then how the temperature affect the laptop battery?

  1. 0-40 is the most reasonable working environment

    it have an impact on using notebooks, such as the humidity, static electricity, temperature, and so but the lithium-ion Dell xps m1330 battery on the temperature is most sensitive to high or low temperatures, too high or too low a temperature will have negative impact on normal circumstances the battery, Lithium-ion battery limits of the ambient temperature is -20 ~ 60 , while the 0 ~ 40 was the most reasonable working environment, but should play a laptop batteries performance potential, 20 or so is the best use of the environment.

  2. -25 below will affect the battery life

    Although the laptop battery allows -20 environment, to use, but this will be the battery charge and discharge performance impact is very large, usually, the ambient temperature, the lower, the vostro 1500 battery inside the active material of the activity the lower the electrolyte resistance and viscosity The higher the ion diffusion more difficult, the battery charge and discharge is not easy.

    For example, when the ambient temperature is below zero, the battery charge-discharge efficiency will be greatly reduced, thereby charging rate will be very slow, full of power after the power of time and only had about 60%, when the ambient temperature falls below the minimum temperature limit (for example, -- 25 ), the battery for Sony np-fh100 electrode reaction rate is very low, the electrolyte may even consider freezing point, the battery performance may be only 10 percent, seriously affecting battery life.

  3. 60 and above may explode

    With the low-temperature case, if the laptop battery ,Sony np-qm71d is used in high-temperature environment, it is same to affect the battery charge and discharge efficiency and battery damage is more serious, such as the use of low-quality charger or the charging time is too long to make the battery heat large, when the charge temperature exceeds the maximum limit temperature, it will destroy the battery for Fujifilm np-95 within a chemical balance, causing the battery to the material performance degradation, the battery life reduced.

By the same token, the battery during discharge time, that is we use the notebook, because of the battery internal short circuit or Nikon en-el8 battery design flaws, if the temperature exceeds the maximum limits of battery capacity decline in life receded, serious situation will have seen an explosion, burning and other accidents.

Lithium-ion battery is closely related to the safety and material properties

At present lithium-ion batteries have become the basic equipment supply,such as xps m1730 battery phones, laptop computers and other mobile electronic devices, but also has begun to apply to light electric vehicles and hybrid electric vehicles. However, due to rapid demand growth ,the cost of lithium-ion batteries become increasingly prominent, due to the improvement of energy density batteries, battery safety accidents have also been reported.

Using a variety of ways to increase security

the safety of the battery is involved in battery material, battery for Canon LP-E5 design, manufacture and application in many aspects, simply changing the cathode material can not completely guarantee the safety of the battery. Only the main material is necessary to carefully select the anode material, electrolyte and battery separator, such as a lithium-ion battery anode materials are carbon materials, metal oxides and alloys, graphite material is still today a major lithium-ion battery anode material, However, its safety performance is lower than the hard carbon materials, while the spinel lithium titanate anode material has a higher security. it is to improve the safety of lithium-ion Sony NP-FC11 batteries techniques to use resistant and higher temperatures ,new electrolyte membrane and processing of flame retardants.

to Affect the safety of lithium-ion batteries is a major factor in battery,Canon NB-4L electrode materials, electrolytes and manufacturing processes and use conditions. lithium-ion battery weighing of a cell phone is about 20 grams, the basic requirement is that the probability of security incidents occurred less than one in a million.As the battery capacity increases, the possibility of security incidents significantly increase . Therefore, lithium-ion batteries are made into the power battery ,its safety performance must be improved , the the single cell is greater , asking for security indexes also higher. Such as the commonly used lithium cobalt oxide and graphite as a lithium-ion Nikon EN-EL8 battery anode material for the positive, the battery large-scale post-licensure safety will not be guaranteed.

when China started to carry out research and develo lithium-ionFujifilm NP-95 battery electric vehicles, there have been a number of explosions and burning accidents, one of the main reason is that the lithium cobalt oxide are usually used as cathode material for batteries.Then search for alternative cathode material for lithium cobalt oxide to address the security issues is the top priority issuefor driving force-type lithium-ion battery R & D .Japan's mass-produced lithium manganese battery for Fujifilm NP-120 capacity is small monomer, such as publicly reported for the 3000 Tokyo Electric Power car battery is 216 13Ah lithium manganese batteries.

safety of Lithium iron phosphate as cathode is more better

On the cathode, the lithium iron phosphate (LiFePO4) Charge-state thermal stability is high ,oxidation capacity of the electrolyte is low, it is with better security, and can be used to make a larger battery,Sony NP-QM71D.LiFePO4 theoretical capacity is 170 mAh / g, relative to the lithium metal ,voltage is 3.5V, if it is made into materials, the actual reversible capacities is greater than 160 mAh / g. Compared with other materials, lithium-ion in the chemical diffusion coefficient of LiFePO4 is lower ,electronic conductivity at room temperature is far below that of other cathode materials, to enhance the material properties and the realization of applications by reducing the material size, coated with conductive agent means ,it can bring the defect of low density, the volume is too large and electrolyte battery for JVC BN-V428 usage is more.

The first synthesis of lithium iron phosphate(it is the important materail of battery,JVC BN-V408) way is solid-phase reaction of JB Goodenough. This method is simple , convenient, and easy to operate,disadvantage is the longer cycle and it is difficult to control the stability of the batch from synthetic products. How to to prevent the oxidation of divalent iron is the synthesis of critical control points in the heat treatment and powder processing. There are a lot of R & D team to develop the carbon-thermal reduction method, co-precipitation, hydrothermal method, spray pyrolysis method.

Compared to other lithium battery for , Kodak KLIC-7002 material, lithium iron phosphate is still very young. Some people say that the battery used in electric tools, it was said that it would apply to electric bus batteries, the initial opening up is the need to be encouraged.

Japan has a monopoly in the field of lithium-ion Kodak KLIC-7003 battery, famous companies have built large-scale lithium-ion battery production line ,such as Sony, Sanyo Electric, Matsushita Battery, NEC and others , but most manufacturers in addition to maintaining and expanding the production of the original brand, all of them is using their own advantages to develop lithium-ion battery of new products. Overall, Japan remains the leading countries power battery for Kodak KLIC-8000technology, its power batteries and their mass production of key materials technology has matured, the performance has almost meet the demand for electric vehicles.

About Li-ion batteries

Li-ion battery came from lithium-evolved. Therefore,before introducing the Li-ion, we must introduce lithium Dell precision m90 series battery first. For example, the former camera button cell lithium batteries belongs to Li-ion battery. cathode material of Lithium battery is lithium metal. Anode material is carbon material, we call this cell as lithium batteries.

Cathode material Li-ion is lithium cobalt oxide, cathode material is carbon material. Lithium-ion Sony np-fp70 battery go through the cathode material of the type of carbon in the negative and move out to achieve the battery charge and discharge process, so people called Li-ion.

Advantages of Li-ion battery are:
  1. The single cell for Panasonic cga-du21 voltage is up to 3.6-3.8V;
  2. The large energy. Present HYB Battery steel can achieve more than the actual energy 100-135W.h/Kg and 280-353W.h / L (2 times and Ni-Cd, 1.5 times the Ni-MH)
  3. Long cycle life. Li-ion Dell xps m1330 battery can reach 500 times more than normal in general, or even 1000 times.
  4. Safety performance is good, pollution-free, no memory effect. As the predecessor of lithium Li-ion batteries,Kodak klic-8000 , due to the formation of dendrite lithium lithium easily and short-circuit, this shorten its applications; Li-ion does not contain cadmium, lead, mercury and other elements of the environment pollution; part of the process (such as around the node-type) and Ni-Cd batteries there is a major drawback for the "memory effect", it seriously hindered the use of batteries, but Li-ion Kodak klic-7004 battery does not exist this problem.
Disadvantages of Li-ion battery are:
  1. Dell precision m series battery costs are higher. it mainly reflected in the price of LiCoO2 high (Co fewer resources), and electrolyte purification system is difficult.
  2. Can not be high-current discharged. As the organic electrolyte system, and other reasons, compared to other type of batteries, the battery internal resistance is more larger, so we called for a smaller current density forJVC bn-vf823 Battery , generally ithe discharge current is 0.5C below,it is only suitable for small and medium-current electrical to use.
  3. Iit need to protect the line control.

     

  4. Small self-discharge. Room temperature, full power Li-ion Dell inspiron 3500 d300gt battery storage 1 month self-discharge rate is about 10%, it is much lower than Ni-Cd of 25-30%, Ni-MH 30-35%.

Waste Battery Recycling Technology

The following describes three kinds of waste dry Casio NP-100 battery recycling technology:

a. Artificial separation recycling technology

To classify the dry battery , Sony NP-FH100 in general , simplely cut a battery to be open, artificial leather isolated zinc, plastic cover, carbon rods and so on from battery, put the remnants of Mn02, water, a mixture of manganese stone anyone to return to brick kiln calcination, made of dehydrated Mn02, this method is simple, but the occupation of labor are not more cost- effective.

b. Pyro-recycling technology

Generally it is to classify battery,such as Panasonic CGR-S003,and make them broken, then send into the rotary kiln at 1100 ~ 1300 degrees Celsius of high temperatures, zinc and zinc chloride is oxidized to zinc oxide, and exhausted with the flue gas , recovery zinc oxide with cyclone, the remaining of cyclone ,two manganese oxide and manganese stones get into the water, residues, further recovery manganese and other substances.this method is easy, the average smelter is Needless to add equipment, so zinc from Kodak KLIC-7001 battery can be recycled .

c. Wet-recycling technology

According to zinc, manganese dioxide can be dissolved in acid in principle, when the waste dry batteries forCanon NB-2LH is classified andbroken, placed it in leaching tanks, and obtained zinc sulfate solution by adding dilute sulfuric acid (100 ~ 120g / L), the rule of law must be used electrolytic metal zinc,copper residues is separated by washing cap, carbon rods, obtained Mn02 from battereyby calcination of manganese the residues Mn02, water, stone . The methods divided roast a leaching method and direct leaching.

Compared with fire method to recyce battery,Kodak KLIC-7001 wet method less investment , low cost, factory speed, high-profit, technical flexibility and other advantages, butit can not guarantee full recovery of harmful ingredients.

Installation of photovoltaic cells market will be launched in china

Due to the high cost of solar photovoltaic power generation, the development of the industry are mainly from subsidize of country policy to drive around the world . with Government support policies of Photovoltaic power generation in all countries, the world photovoltaic industry overcome the international financial crisis ,and began warming, combined with the cost of investment down, which make the investment increase in solar energy.China has become the world's largest photovoltaic Sony NP-FC11battery-producing countries, its global production of photovoltaic Samsung SLB-0637 battery occupy about 40% of production.

From the capacity point of view, in 2008 the world's installed photovoltaic Canon BP-911 battery 5600MW, up to 134%. China's installed capacity in 2008 was only 40MW, only 0.7%, we can see, the Chinese market to install photovoltaic cells is to be started , the market has great potential.

By the end of March the Ministry of Finance issued "on accelerating the implementation of solar PV building applications opinions" and so on, because in 2009 the principle of subsidy standards is set at 20 yuan on / Wp (the photovoltaic Minolta NP-200 battery accounted for the most part), it means that the cost of photovoltaic power generation of electricity can be reduced to 0.58 yuan / kWh, the domestic PV demand started. We expect that the subsidy program is only the beginning, in May it is expected to launch a "New Energy (including the photovoltaicKONICA MINOLTA NP-400 battery)Industry Promotion Plan", and is expected to further the introduction of relevant policies.

Crystalline silicon thin-film photovoltaic Sony NP-BG1 battery and photovoltaic cells will increase both, ti compare them , thin-film batteries take advantages of the cost. cost limit Of crystalline silicon cells is 1.27 U.S dollars per watt . while the cost limits of the thin-film Nikon EN-4 batteries is below one U.S. dollars per watt . We estimate the current installed capacity of monocrystalline silicon Sony NP-FH100 battery cost 19 yuan / wp, the cost of thin-film solar cells installed capacity of is 12 yuan / wp.Both are expected to grow, share of thin-film batteries increased .

based on needs of Solar energy industry, all the links of the different levels of benefits, we give priority to recommend high-end thin-film Olympus BLM-1 battery manufacturers and component suppliers, followed by crystalline silicon battery, or integration of upstream and downstream manufacturers,the last one is the upper reaches of polysilicon crystalline silicon cells.

a new fuel cell technology-Urine

U.S. scientists have recently used a new technology to male urine supplied power for cars, can also provide energy for home appliances and other equipment(it completely see as a kind of Sony NP-FC11battery to use).

Scientists extracted from the urine of large and cheap hydrogen by using nickel electrodes, while hydrogen can be as a motor fuel or used in the manufacture of fuel Samsung SLB-0637 battery ,It is reported that a cow's urine to provide adequate hot water energy for 19 families.

Urine, or hydrogen power technology is essentially the use of technology. Because the chemical composition of urine contains hydrogen(while hydrogen is the major components of battery,Canon BP-911),there is less electricity to obtain hydrogen through the urine than through water .rea molecules are the main component of urine, which contains four hydrogen atoms and two nitrogen atoms.put a special nickel electrodes from Samsung SLB-0637battery inserted into the urine container, and release hydrogen after pass on the current

The researchers invented a prototype fuel Sony NP-FH100 battery smaller urine, could only produce 500 milliwatts of electricity. Their next goal is to achieve industrial production and widespread use.It is estimated that for every gallon of urine is theoretically possible to ensure urine powered fuel Sony NP-FC11 vehicles running 90 miles ,a refrigerator-sized fuel Samsung SLB-0637can produce urine 1000 watts of power.

Chemists pointed out that a chicken farm produce electricity through the urine sufficient to maintain its normal operation(because it can be completely see as a Kodak CR-V3 battery-save up to prepare for using). It is reported that the livestock farms are required to excrete waste treatment in the United States ,the urine of new technologies for clean energy will undoubtedly be able to get double benefit effect.
