Si anode for next-generation lithium-ion battery

Abstract(#br)Si-based materials with high theoretical storage capacity and low working potential are one of the ideal anode materials for next generation lithium ion batteries, but their large volume change and low conductivity obstruct the commercial application. This article presents a brief overview of insights of charge-discharge mechanism and the main challenges of Si-based anodes in the past few years, and outlines typical solving strategies, new mechanism, advanced characterization technology and future directions
