What materials are used in cell phone lithium batteries?

Let's talk briefly about lithium ion batteries

Battery cells

The main raw materials of the positive electrode are lithium cobalt oxide, PVDF binder and l 'conductive agent

Raw materials for negative electrode mainly include graphite, SBR binder, conductive agent

Separator: pp, pe, etc.

Some other insulating materials, nickel tape for connection, etc.

The final label packaging is almost okay

1. Powdered materials are non-toxic, but protection against inhalation is required

2. SBR has some degree of toxicity, so avoid inhalation; NMP has slight toxicity, but no obvious impact, it is necessary to avoid strong contact corrosiveness aith the body

3 The electrolyte has some toxicity, avoid excessive inhalation and corrosiveness
