Електрохімічні властивості літій-марганцевих шпінелей залежно від складу вихідних компонентів при синтезі

Abstract

The electrochemical behavior of Li−Mn spinel samples is studied on the cycling at high discharge densities (over 5 C). The dependence of the specific capacity on the composition of the original substances used in the synthesis has been established. The diffusion coefficients for the spinel samples obtained have been calculated. It has been shown that, at high discharge densities, the capacity depends on the diffusion coefficient of lithium in a solid electrode material.
