Kinetics of Anodic Dissolution of Lithium out of Li x C6 Electrodes in Nonaqueous Lithium Perchlorate Solutions

Kinetics of processes occurring during anodic dissolution of Li _x C₆ electrodes formed in structures of carbonized fiber and cloth (CC) in solutions of lithium perchlorate in a mixture of propylene carbonate and dimethoxyethane is studied. It is shown that the Li _x C₆ (CC) electrodes have an approximately three times greater intercalation capacity, which is caused by specific features of the structure of CC. Values of the initial concentration of lithium defects in the structure of a surface layer of the CC matrix and the diffusion coefficients for lithium in the temperature range 293–323 K are calculated.
