针对主流的锂聚合物和磷酸铁锂两种动力锂电池进行测试分析和性能比较。分析结果表明，锂聚合物电池在大电流恒压放电性能、比功率和比能量方面优于磷酸铁锂电池。而在安全充放电和耐用性方面磷酸铁锂电池更具优势。

英文摘要：

In this paper, the high-rate discharge performance of two kinds of mainstream lithium battery of lithium polymer and LiFePO4 battery was measured and analyzed. 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 charge-discharge safety and durability, LiFePO4 battery has some advantages.
