Abstract: 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 LiMn2O4 and olivine-type LiFePO4 are 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 LiMn2O4 and LiFePO4 are right choices for power-type and energy-type applications, respectively.

Key words: lithium-ion battery, cathode material, energy storage
