Abstract: 100?Ah lithium-ion power batteries were prepared by using spinel LiMn2O4 cathode material. The result shows that such battery boast superior charge-discharge performance and good safety performance. The 400Ah battery pack, assembled with four such batteries, was installed in buses for long-term trials in Beijing. Tests indicate that both the batteries and the vehicles run well and spinel LiMn2O4-based Li-ion secondary batteries can fully meet the requirements of electric vehicles (EVs).
