Bifunctional effect of laser-induced nucleation-preferable microchannels and in situ formed LiF SEI in MXenes for stable lithium-metal batteries

A bifunctional effect of laser-induced aligned lithiophilic microchannels and in situ formed LiF-enriched SEI on lithium deposition is proposed by using fs laser on the MXene membrane. Stable Li plating/stripping is achieved at 20 mA cm⁻² in an asymmetric cell.
