Abstract: Replacing traditional liquid electrolytes by polymers will significantly improve electrical energy storage technologies. However, the ion transport mechanism in polymers has been one of the main barriers to further improvement in Li-ion batteries and is still not completely clarified. In an effort to gain a better understanding of the conduction phenomena in electrolytes, a comprehensive survey of all transport mechanism including solvation, segmental motion and hopping, is presented here. Included are a survey of the fundamentals of diffusion and conductivity in polymer electrolytes; recent developments in Li salts; and a detailed discussion about ion transport mechanism with representative references.
