Pollution prevention, lithium power is only the best choice for the time being.

On April 26, the business daily reported that "recycling of waste electronic products is expected to be rewarded", which aroused widespread public concern. The Municipal Environmental Protection Bureau temporarily does not encourage the centralized recycling of nickel cadmium batteries and other batteries that have reached the relevant mercury content requirements, and relevant experts say that we should take scientific and technological means to eradicate the problem from the "source".

Lin, director of waste solid center of Hefei Environmental Protection Bureau, said that centralized recycling of waste dry batteries was not recommended for the time being. In the aspect of municipal supply and marketing cooperatives, "prize recovery" strategy is still in the research stage. But the expert‘s opinion is, must treat the root cause from the manufacture material grasps.

Professor Chen Chunhua of School of chemistry and materials science of University of science and technology of China told the reporter, "as the battery mainly contains a variety of inorganic materials, no degradable battery has been developed. However, in order to achieve good battery performance and no pollution, high-performance lithium-ion battery is the best choice at present. They are the main power supply of portable electronic devices, with excellent cycle performance, high charging efficiency and long service life. The most important thing is that they do not contain lead, cadmium and other toxic substances, so they are more green and environmentally friendly.

In addition, according to Professor Chen, Li ion battery is only the best choice for the time being, because the electrolyte of this kind of battery contains fluorine and is somewhat corrosive
