The Anode Materials for Lithium‐Ion and Sodium‐Ion Batteries Based on Conversion Reactions: a Review

Abstract

AbstractDue to its characteristics of not being constrained by the lattice structure and cation size, electrochemical conversion reaction is becoming an increasingly prominent type of electrochemical reaction. Lithium‐ion batteries can achieve superior performance by utilizing conversion reactions, Moreover, Sodium‐ion batteries are expected to become alternatives to lithium‐ion because of the plentiful sodium resources. This review discusses the most current developments and unmet needs in anode materials based on conversion reactions of Lithium‐ion and sodium‐ion batteries, as well as various synthesis techniques, morphological characteristics, and electrochemical properties.
