Find relevant information from the Internet, has been a lot of information has made me more aware of the importance of strengthening the management of Laptop battery recycling. Who can do this?

People in everyday life based on the use of chemical battery, popular debate is to rely on the corrosive effect that produce electricity, while the corrosion contain large quantities of heavy metal pollutants. When he is thrown randomly mixed in the general life of garbage accumulate in the environment, these toxic substances will slowly overflow the stack, after the rain washes the infiltration into the soil or groundwater sources, then enter the human food chain through crops. These toxic substances accumulate in the human body would be difficult to exclude a long-term damage to the body of a person, and even cancer. Waste VGP-BPS13 batteries contain hazardous heavy metals – mercury, lead, cadmium, chromium, etc., according to 1998 “, registered in the national hazardous waste” in the description, the mercury consumption of mercury contaminated food produce methylmercury poisoning, dizziness, numbness of peripheral, memory loss, mental disorders and even death, but also affect the development of pregnant women with fetal malformations. Lead: lead consumption of food will affect the enzyme and synthesis of normal hemoglobin, affect the nervous system, lead accumulated in bone and kidney, there is the effect long-term potential long. Cadmium: Entering bone disease may cause bone pain, contraction of softening of the bones, the high incidence of pathological fracture and finally the power, under pain of death. Cr: chromium in the body, found in the liver and kidneys, it seemed the Hepatitis disease and nephritis.

There is such a data set: one button cell battery can contaminate 600,000 liters of water, equivalent to the amount of water, the life of a person! A battery can make a square meter of soil crop failure! Annual consumption of China for the button cell battery is only 7 billion! Currently, companies producing battery China 1400, the annual production of 14 billion VGP-BPS9A batteries! Shocking! Ah! So many batteries, how much recycled after being used out? We do not know, and we see an entirely different story is this: in the urban fringe of the mountain or the river on both sides of garbage dumps in the rural village before the village Gougou Kankam land where everywhere is set Disposal of used batteries.

Waste batteries may be small, Queshen major damage. However, due to pollution, waste batteries as waste, air and water pollution, as would any sensory think she has a great hidden, so they do not received due attention. At present, China has become the production and consumption of battery power, pollution of batteries is an urgent need to solve a major environmental problem. On the size and weight, the batteries used in household waste are negligible, but its harmful effects is very large, batteries containing mercury, cadmium, lead and heavy metals. Highly toxic mercury, lead can cause neurological disorders, nephritis, etc. cadmium major cause of kidney and bone diseases – osteoporosis, osteomalacia and fractures. If the batteries mixed with household waste in the landfill, over time, leaching of heavy metals can contaminate groundwater and soil.

Looked through them, is not it shocking that we should do something! We can not wait until the damage to come.

According to the different types of fuel battery electrolytes can be divided into:

(1) Fuel batteries at low temperature, such as fuel battery solid polymer electrolyte (PEMFC) and alkaline fuel battery (AFC);

(2) Phosphate acid fuel battery (PAFC);

(3) Fuel battery molten carbonates (MCFC);

(4) Solid oxide fuel battery (SOFC) and so on.

SOFC is the second PAFC, MCFC greater efficiency of energy conversion after the third generation system, fuel battery, is considered the most effective systems and universal power generation, especially as decentralized power plants , scientists from various countries are being attracted great interest. It is the fuel and oxidant gases by an ion-conductive ceramics, and generation of strong electric power and energy for the state apparatuses of conversion, it is also known as fuel batteries ceramic.

Include SOFC electrolyte and two electrodes. In the cathode, the air of oxygen dissociation into oxygen ions, two electrodes through the solid electrolyte membrane between migration to the anode / electrolyte interface of the reaction of fuel. Outside the circuit, the anode to the cathode of the electron flow generated DC. SOFC solid electrolyte is the most central parts. Her performance is not only a direct impact on the work of the VGP-BPS10 battery temperature and the efficiency of power conversion, but also determines the required matching electrode material and the corresponding choice of preparation technology. Discovered so far may be used for SOFC oxygen ion conductor mainly fluorite phase structure of ZrO2-based, CeO2-based, Bi2O3-based materials and the perovskite-type structure LaGaO3 based materials.

In addition to the overall merits of the SOFC fuel battery also has the following characteristics: Adaptability of the fuel can be a variety of fuels, including the case of carbon-based fuels to run, does not require the the use of noble metal catalyst, the use of all semiconductor components state, there is no right, leakage corrosion management issues; blocks of solid, flexible, and therefore the size and the ‘install location. These characteristics make fuel efficiency for electricity production at the time the cycle has the potential of more than 60%, while the effectiveness of the entire system, up to 85%, 1MW SOFC / M3 power density, the design of the block may be as high as for 3MW / m 3. In fact, SOFCs can be used to produce energy, thermal recycling, transportation, aerospace and many other areas of space known as the 21st century green energy.

SOFC research and development of the future based on the following aspects:

1. New electrode materials and other components of the VGP-BPS13 battery development.

Modification of other SOFC components, allowing the system to optimize the structure to meet the average fuel battery operation temperature, the development of the temperature conditions in a given activity in the same time, they met the electrolyte performance is the electrode material, improve the structure of micro-electrodes. A nano-electrode is a possible route. It has small particles, increasing the three-phase industry (catalytic center) in length and electrode / contact area of the electrolyte, which significantly reduces the interface resistance, may also reduce the thickness of ‘electrode, so that gas is more easily spread in the three-phase interface, decreases due to concentration polarization electrode caused by the reduced efficiency of the battery.

2. Head Proton and Proton – Development of ion mixed conductive electrolyte.

For a proton conductor as electrolyte, the water produced in the oxidizer side, so there will be no driver of oxygen ions as electrolyte, as, after the reaction of the fuel batteries needed to remove water fuel. When using methane gas and other hydrocarbons, only the pyrolysis of these fuels can be considered as the fuel hydrogen proton conducting fuel batteries, while the remaining part of the restructuring could serve as a useful product is retained by the reaction of batteries such as ethane, after their return – availability of ethylene. Some electrochemical reaction must use the proton conductive material. Such as emissions of H2S industry to cope with this fuel VGP-BPS11 battery can produce electricity at the same time, be a useful byproduct of S2.

3. Study of the mechanism of proton conduction and to develop sufficiently in the conductivity of proton-conducting temperature.

This is a promising line of research. It must be said – proton mixed conductor of ions is a solid electrolyte, to find the material itself is a new challenge, which, for deepening our understanding of new SOFC has a special meaning.

4. New concepts and methods.

The recent emergence of the single battery fuel chamber is a new concept. Despite its many shortcomings, but it is a research direction is worthwhile. His main interest lies right to our future design of the battery to provide useful inspiration. For the structure of the electrode material, the majority of electrodes traditional asymmetric electrodes, said cathode and anode materials used in the individual. If you are using symmetric electrodes, the battery performance will be? It deserves to be studied. For methods of VGP-BPL11 battery preparation, the method currently used mostly expensive, finished product rate is low. Research and development of soft chemical preparation routes, the introduction of light conditions, methods of physical preparation is required to have a strong competitive advantage.
