摘　　要：The burgeoning demand for modern electronic devices and electric vehicles has driven the development of efficient,reliable,and environmentally friendly batteries[1,2].Lithium–sulfur(Li–S)batteries with high theoretical capacity(1672 mA h g1)and energy density(2600 W h kg1),have garnered significant interest in both academic and industrial research[3,4].However,the widespread production and commercialization of Li–S batteries are impeded by the inherent characteristics of sulfur and lithium,along with their complex electrochemical behaviors.Notably,challenges such as the polysulfide shuttle effect and the slow kinetics of the sulfur nucleation/decomposition reaction hinder capacity utilization and cycling stability.To overcome these challenges,innovative electrocatalyst strategies aimed at enhancing activity have been explored.
