【Abstract】 This paper focuses on the effects of LaCoO3 on the performance of lithium-air battery with different preparation methods. XRD,TEM and electrochemical test are applied to reveal the fact that the perovskite La CoO3 prepared by electrospinning technique has better performance in lithium-air battery than by sol-gel method because its wiener structure generates more holes which is helpful to the shuttle effect of lithium ions.更多还原
