Abstract Electrocatalysts can inhibit the shuttling of lithium polysulfides (LiPSs) in Li–S batteries by enabling catalytic conversion LiPSs. In this research, heterogeneous Cu 3 P‐Cu 2 O nanoparticles anchored on porous carbon network (Cu O/PC) are investigated to stimulate reaction kinetics LiPSs conversion. At heterojunction interface, high electron density measured functional theory energizes transfer, anchoring The strong interfacial coupling effect generated heterostructure endows active sites with promoted adsorption capability. improved sulfur reduction and Li S activation suppress shuttling. Remarkably, cells equipped O/PC@S cathode marked capacity 1254.3 mAh g −1 at 0.2C ultrahigh cycling stability (0.021% decay rate per cycle after 1200 cycles 4C). Considering practical applications, cathode‐based pouch cell exhibited an initial specific 1069.5 a energy 378.8 Wh kg . This work established pathway for regulating through copper‐based catalysts, exhorting design highly efficient catalysts batteries.

Electric vehicles (EVs) must be used as the primary mode of transportation part gradual transition to more environmentally friendly clean energy technology and cleaner power sources. Vehicle-to-grid (V2G) has potential improve electricity demand, control load variability, sustainability smart grids. The operation principles V2G its varieties, present classifications types EVs sold on market, applicable policies for business strategy, implementation challenges, current problem-solving techniques have not been thoroughly examined. This paper exposes research gap in area accurately portrays difficulties future deployment globally. investigation starts by discussing advantages system necessary regulations commercial representations implemented last decade, followed a description technology, charging communication standards, issues related EV batteries, solutions. A few major were brought light this investigation, including lack transparent model V2G, absence stakeholder involvement government subsidies, excessive strain that places adequate bidirectional introduction harmonic voltage into grid, unethical unscheduled practices. results recent studies publications from international organizations altered offer answers these constraints and, some cases, highlight need further investigation. holds enormous potential, but plan first needs lot financing, teamwork, technological development.
