摘要

Silicon is considered as a promising candidate for next-generation lithium-ion battery anodes. However, severe capacity fading caused by volume change during Li-ion insertion and extraction hinders its practical application. In this work, gold granular film and polyvinylidene fluoride coating are sequentially prepared on the deposited Si film to solve the aforementioned problem.
