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.
Compared to external protection devices (such as BMS, OSD, CID), the internal protection of overcharge additives are more effective. 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.
In this paper, the overcharge performance of a commercial pouch lithium-ion battery with Li y (NiCoMn) 1/3 O 2 -Li y Mn 2 O 4 composite cathode and graphite anode is evaluated under various test conditions, considering the effects of charging current, restraining plate and heat dissipation.
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.
All-solid-state lithium metal batteries with nickel-rich layered oxide cathode All-solid-state lithium metal batteries (ASSLMBs) employing nickel-rich layered oxide cathodes show the potential to meet the requirements for high energy density and safety. In recent years, significant progress has been made in ASSLMBs [ 121 ].
In the standards or regulations, the overcharge performance of single lithium-ion battery is evaluated through several overcharge tests, during which a controlled current is applied to the tested battery (e.g. 1/3 C) up to a set of charge limits (e.g. 2.0 SOC, 1.5 times the upper cut-off voltage).
