Problems solved by technology

[0004] The main component of the positive electrode material of lithium-ion batteries is LiCoO2. my country is a cobalt-poor country, and the natural storage capacity is low. Metal cobalt mainly depends on imports to meet demand, and cobalt is a heavy metal element. The simple treatment of lithium batteries will make the cobalt contained in it Heavy metal elements such as heavy metals accumulate in the natural environment, causing groundwater and soil pollution, which will seriously endanger human health
