Low‐temperature performance optimization of LiFePO4‐based batteries

Abstract LiFePO 4 is one of the most widely used cathode materials for lithium‐ion batteries, and the low‐temperature performance of LiFePO 4 ‐based batteries has been widely studied in recent years. Herein, a 3.5 Ah pouch‐type full battery was assembled using LiFePO 4 as the cathode and artificial graphite as the anode. For the LiFePO 4 ‐based cathode, carbon‐coated aluminum foil was selected as the current collector, and a 0D–1D–2D multi‐scale conductive network was introduced into the electrode. Notably, both the carbon‐coated current collector and novel conductive network could significantly reduce the internal resistance of the LiFePO 4 ‐based battery, thus improving its electrochemical dynamics and low‐temperature performance. This paper provides a theoretical basis for the development of low‐temperature LiFePO 4 ‐based batteries.
