Abstract: Lithium-ion batteries may be slightly overcharged due to the errors in the Battery Management System (BMS) state estimation when used in the field of vehicle power batteries, which may lead to problems such as battery performance degradation and battery stability degradation.
Lithium Iron Phosphate batteries provide excellent power density and safety when used properly. However, issues can still arise during operation. By understanding common protection mechanisms and troubleshooting techniques, battery performance and lifetime can be maximized.
LIBs with lithium-ion iron phosphate (LiFePO, LFP) as a cathode was widely used in home appliances and electric vehicles, etc., which has many advantages such as low cost, reduced thermal hazards and lower oxygen generation than other lithium transition metal oxide batteries due to the strong bonding between oxygen and phosphorus.
These results from the limited comparison indicate that the HRR is highly dependent on the cathode composition and the increase of Ni vastly intensify the fire severity of LIBs. For different chemistries, the batteries burn more violently and possess higher fire risks during overcharging. 3.4. Mass Loss and Residue
