Under the backdrop of the accelerating transformation of the global energy structure and the deepening of the “carbon neutrality” goal, building an efficient, safe and sustainable large-scale electrochemical energy storage system has become a key direction that urgently needs to be broken through in the energy field. As well as, Lithium-ion batteries have stood out among numerous energy storage technologies due to their extremely high energy density, long cycle life, and excellent safety performance. As an important component of lithium-ion batteries, cathode materials have received extensive attention, among which lithium iron phosphate cathode material has been widely applied due to its outstanding safety performance and long cycle life. This research focuses on lithium iron phosphate cathode materials and analyzes three modification methods, namely surface coating, bulk doping, and morphology and structure regulation, to address the current limitations of poor conductivity and slow ion movement of lithium iron phosphate cathode materials.
