There is no doubt that the waste battery is harmful to the environment. However, the pollution brought to the environment by the casual discarding of a small battery is unimaginable. A small waste battery can make 1 square meter of land lose its use value, can let 10 cubic meters of water pollution, but because of the harm of this pollution to the environment has a certain concealment, it can not be like garbage, air, water resources can be felt, which leads to many people to ignore. In fact, the fundamental solution to this problem is to produce green batteries, so which kind of battery is more conducive to green environmental protection? The following is the power business bar to do a detailed analysis. Countries invested a lot of research strength in recent years the research and development of green environmental protection battery, many have been used in a lot of, such as mercury-free alkaline zinc manganese dioxide battery and rechargeable batteries, lithium or lithium ion plastic battery and fuel power lithium-ion batteries, as well as the use of solar energy into electrical energy photovoltaic cells belong to the category of green environmental protection.
Lithium ion battery is the most production and use of a green battery. It is made up of carbon that can embed and deembed lithium ions as a negative electrode, metal oxide that can inversibly embed lithium as a positive electrode and organic electrolyte. Its operating voltage is 3.6V, so one lithium-ion battery is equivalent to three cadmium nickel or nickel metal hydride batteries, and the energy is much more than them.
