Abstract: Inorganic-based lithium mixed electrode materials have a low charge transfer rate and thus have poor fast charging or discharging characteristics. Positive electrode active materials include LCO (lithium cobalt oxide, LiCoO2), NCM (nickel cobalt manganese, Li(NiCoMn)O2), NCA(nickel cobalt aluminum, Li(NiCoAl)O2), LMO(lithium manganese oxide, LiMn2O4), LFP(Lithium iron phosphate, LiFePO4), etc. High nickel technology is attracting attention because if nickel is used a lot, the capacity of lithium ions can be increased. However, as the content of nickel increases, the reactivity increases, resulting in a risk of explosion of the battery and deterioration in cycle life characteristics. As the negative active material, carbon, transition metal oxide, nickel metal, silicon-nickel alloy, and the like may be used. As the carbon, natural graphite, artificial graphite, soft carbon, hard carbon, etc. can be used. As the transition metal oxide, Co3O4, CoO, FeO, NiO, and the like can be used.
