摘　　要：Rechargeable metal-sulfur batteries with the use of low-cost sulfur cathodes and varying choice of metal anodes(Li,Na,K,Ca,Mg,and Al)represent diverse energy storage solutions to satisfy different application requirements.In comparison to the highly-regarded lithium-sulfur batteries,the use of nonlithium-metal anodes in metal-sulfur batteries offers multiple advantages in terms of abundance,cost,and volumetric energy density.Although with the same sulfur cathode,metal-sulfur batteries show considerably differences in the electrochemical reaction pathway and capacity fading mechanism.Herein,we provide an overview of correlations and differences in metal-sulfur batteries,highlighting the knowledge and experience that can be transplanted from lithium-sulfur to other metal-sulfur batteries.We first discuss the historical development and the electrochemical reaction mechanism of various metal-sulfur batteries.This is then followed by an analysis of key challenges of metal-sulfur batteries including polysulfide shutting,cathode passivation,and anode stability.Finally,a short perspective is presented about the possible future development of metal-sulfur batteries.
