摘要
针对锂离子电池在电力储能中的应用,从电化学性能、安全性能以及价格等方面比较了岩盐结构LiCoO2、尖晶石型LiMn2O4和橄榄石型LiFePO43类主要的锂离子电池正极材料,论述了它们各自的优点和不足之处。对不同正极材料的锂离子电池在储能领域存在的问题进行了分析,对各自的应用前景进行了展望,认为LiMn2O4和LiFePO4分别适用于功率型应用和容量型应用。
In view of the application of lithium-ion batteries in electrical energy storage systems,three kinds of main cathode materials of lithium-ion batteries,i.e.rock-salt LiCoO2,spinel-type LiMn2O4and olivine-type LiFePO4are studied in the aspects of their electrochemical and security performance as well as their costs.The existing problems and application prospects of different types of lithium-ion batteries in electrical energy storage systems are revealed,which concludes that LiMn2O4and LiFePO4are right choices for power-type and energy-type applications,respectively.
