Lithium‐metal batteries show great promise as the next generation rechargeable batteries with high theoretical energy density. Unfortunately, Li metal anodes suffer from serious corrosion of the electrolyte and by‐products shuttled from cathode during cycling, such as O2 in Li‐O2 batteries. Here, an oxygen‐resistant and self‐eliminating passivated layer is fabricated through a Wurtz‐type reaction...
Rechargeable alkaline Zn–air batteries (ZABs) are attracting extensive attention owing to their high energy density and environmental friendliness. However, the dilemma of Zn anode, composed of ineluctable passivation and dissolution problems, severely hinders the discharge and cycling performance of the battery. Herein, the authors propose a chemical buffer layer coated on Zn metal (CBL@Zn) anode,...
Lithium–oxygen (Li–O2) batteries with ultrahigh theoretical energy density have attracted widespread attention while there are still problems with high overpotential and poor cycle stability. Rational design and application of efficient catalysts to improve the performance of Li–O2 batteries is of significant importance. In this work, Co single atoms catalysts are successfully combined with redox...
