A complex polymer with aromatic functional groups, epoxy or propionate, will become a hot spot in the research of overcharge additives for lithium-ion batteries. This review is expected to offer effective overcharge safety strategies and promote the development of lithium-ion battery with high-energy density.
In vessel, aircraft and other place where escape is more difficult, the safe use of lithium-ion batteries requires more attention. Therefore, it is very meaningful to study the overcharge behavior of high-power type lithium-ion batteries (maximum discharge rate 50 C).
As early as 1998, Mao and others pointed out that biphenyls can be used as overcharge protection additives for lithium-ion batteries . As the battery was overcharged to 4.70 V, the biphenyls underwent an electropolymerization reaction, and the internal resistance of the battery increased.
The factors of battery material, charging pattern, and battery structure design on the overcharge effect are also summarized. To some extent, using external protection devices (such as BMS, OSD, CID) can improve overcharging security. But the internal protection of overcharge additives is more effective.
Safety issue is still a problem nowadays for the large-scale application of lithium-ion batteries (LIBs) in electric vehicles and energy storage stations. The unsafe behaviors of LIBs arise from the thermal runaway, which is intrinsically triggered by the overcharging and overheating.
