Lithium iron phosphate is an important cathode material for lithium-ion batteries. Due to its high theoretical specific capacity, low manufacturing cost, good cycle performance, and environmental friendliness, it has become a hot topic in the current research of cathode materials for power batteries.
Under low-temperature conditions, the performance of lithium iron phosphate batteries is extremely poor, and even nano-sizing and carbon coating cannot completely improve it. This is because the positive electrode material itself has weak electronic conductivity and is prone to polarization, which reduces the battery volume.
Current collectors are vital in lithium iron phosphate batteries; they facilitate efficient current conduction and profoundly affect the overall performance of the battery. In the lithium iron phosphate battery system, copper and aluminum foils are used as collector materials for the negative and positive electrodes, respectively.
