英文摘要：

The electrochemical performances of Li ion battery depend on the electrode materials,electrolyte and septum.The transmission path and rate of Li ion in these materials directly affect the electrochemical performances of Li ion battery.Recently in order to improve the energy density and the output power of Li ion battery,a series of studies on the mechanism of lithium ion transport have been carried out.This paper reviewed the diffusion mechanisms of lithium ion in different electrode materials,electrolytes,self assembled membrane and its research progress.The various mechanisms were compared and evaluated.We also pointed out the bottleneck in the mechanism research of lithium ion transfer and hot issues in the futher research.
