18650 6.4V 3000mAh Lithium iron phosphate battery

The battery is generally considered to be free of any heavy metals and rare metals (the nickel-hydrogen battery requires rare metals), non-toxic (SGS certified), non-polluting, in line with European RoHS regulations, and a green battery. An important reason why lithium batteries are favored by the industry is environmental considerations.

But please face it squarely. Lithium batteries are a good part of the new energy industry, but they cannot avoid the problem of heavy metal pollution. Lead, arsenic, cadmium, mercury, chromium, etc. in the processing of metal materials may be released into dust and water. The battery itself is a kind of chemical substance, so there may be two kinds of pollution: one is the pollution of process excrement in the production engineering; the other is the pollution of the battery after it is scrapped.

At present, the most promising cathode materials for power lithium-ion batteries mainly include modified lithium manganate (LiMn2O4), lithium iron phosphate (LiFePO4) and lithium nickel cobalt manganese (Li(Ni,Co,Mn)O2) ternary Material. Due to the lack of cobalt resources and the high content of nickel and cobalt and the large price fluctuations, it is generally believed that it is difficult to become the mainstream of power-type lithium-ion batteries for electric vehicles, but it can be compared with spinel manganese acid. Lithium is mixed and used within a certain range.
