A study of electrochemical kinetics of lithium ion in organic electrolytes

Limiting current densities equivalent to the transport-controlling step of lithium ions in organic electrolytes were measured by using a rotating disk electrode (RDE). The diffusion coefficients of lithium ion in the electrolyte of PC/LiClO4, EC : DEC/LiPF6 and EC : DMC/LiPF6 were determined by the limiting current density data according to the Levich equation. The diffusion coefficients increased in the order of PC/LiClO4
