Electrochemical Properties of Li-Zn Alloy Electrodes Prepared by Kinetically Controlled Vapor Deposition for Lithium Batteries

A alloy electrode prepared by a kinetically controlled vapor deposition (KCVD) is examined for use as the negative electrode for rechargeable lithium batteries. Results indicate that filamentary or dendritic growth of lithium on a alloy electrode prepared by the KCVD technique are dramatically suppressed due to fast diffusion of lithium in the alloy electrode, suggesting that the prepared by the KCVD method may be used effectively to improve the rechargeability of negative electrodes.
