Negative: artificial graphite series, natural graphite series, coke series and so on.
Separator: Polyethylene (PE), polypropylene (PP) and other single or multi-layer microporous film.
Electrolytes: Monobasic, di (meth) acrylates such as propylene carbonate (PC), ethylene carbonate (EC), dimethyl carbonate (DMC), diethyl carbonate (DEC), methyl ethyl carbonate (MEC) Yuan or ternary mixture.
