A review of anode materials for sodium ion batteries
Lithium-ion batteries(LIBs)are used in electric vehicles and portable smart devices,but lithium resources are dwind-ling and there is an increasing demand which has to be catered for.Sodium ion batteries(SIBs),which are less costly,are a prom-ising replacement for LIBs because of the abundant natural reserves of sodium.The anode of a SIB is a necessary component of the battery but is less understood than the cathode.This review outlines the development of various types of anodes,including carbon-based,metallic and organic,which operate using different reaction mechanisms such as intercalation,alloying and conversion,and considers their challenges and prospects.Strategies for modifying their structures by doping and coating,and also modifying the sol-id electrolyte interface are discussed.In addition,this review also discusses the challenges encountered by the anode of SIBs and the solutions.
