Abstract:
As one of the most promising candidates for power sources in electric vehicles and hybrid electric vehicles, lithium-ion batteries need to be further improved by solving problems related to safety issues, high costs, low rate capability, and low energy density. New electrode materials of germanium-carbon composites, Li4Ti5O12, and Li3VO4-based carbon composites and LiFePO4/C/graphene composite cathode have been investigated [1-3].
The Li–S battery is a very attractive energy storage system owing to its high theoretical specific capacity of 1672 mAh g−1 and theoretical energy density of 2600 Wh kg−1. Sulfur-carbon composites and sulfur-conducting polymer composites were prepared investigated as cathode materials for Li/S batteries [4-6].
The rechargeable lithium-oxygen battery currently enjoys great scientific interest because theoretically, it can store significantly more energy, which exceeds that possible with lithium- ion batteries. Cobalt-based and palladium-based cathode materials were synthesised and investigated [7-9].
