Abstract
The present disclosure relates to in-plane modulated, microgradient-patterned (MGP) carbon-coated metal surface as a current collector (CC) for dendrite-free alkali metal plating and stripping with high coulombic efficiency and long cycle life. The specific microstructure and property of the MGP carbon coating of the present disclosure are prepared by scanned CO2 laser in-situ processing of a polymer coating.
