Overcharging is extremely detrimental to lithium iron phosphate batteries; it not only directly causes microscopic damage to the cathode material but also induces chemical decomposition of the electrolyte and the generation of harmful gasses, which can lead to thermal runaway, fire, explosion, and other catastrophic consequences in extreme cases.
Although there are research attempts to advance lithium iron phosphate batteries through material process innovation, such as the exploration of lithium manganese iron phosphate, the overall improvement is still limited.
For example, the coating effect of CeO on the surface of lithium iron phosphate improves electrical contact between the cathode material and the current collector, increasing the charge transfer rate and enabling lithium iron phosphate batteries to function at lower temperatures .
