High-rate lithium battery is the object researched by electric-chemical experts due to the increasing of miniaturization and high-power devices. In this paper, measure and analysis their high-rate discharge performance for two kinds mainstream lithium battery of lithium polymer and LiFePO4 Battery. The results show that lithium polymer battery is more effective than LiFePO4 Battery in constant-current discharge performance, power density and energy density. But in safety charge-discharge and durability, LiFePO4 Battery has some advantages.
