Lithium (Li) metal is the most promising electrode for next-generation rechargeable batteries. In order to push the commercialization of the lithium metal batteries, a kind of nitrogen(N)-doped composite graphene (NCG) adopted as the Li plating host was prepared to regulate Li metal nucleation and suppress dendrite growth. Furthermore, a new kind of sandwich-type composite lithium metal (STCL) electrode was developed to improve its application. The STCL electrode can be used as convenient as a piece of Li foil but no dendrite growth. In a symmetric battery, the STCL electrode cycled for more than 4500 h with the overpotential of less than 40 mV. And due to the creative design, the STCL promises the Li–S battery with a prolonged cycling lifespan.Graphical Abstract
