Description
Summary:Using highly dispersed metal fluoride nanoparticles to construct a uniform fluorinated alloy type interfacial layer on the surface of Li metal anodes is realized by an ex situ solution chemical modification method. The fluorinated alloy-type interfacial layer can effectively inhibit the growth of undesirable Li dendrites while enhancing the performance of Li metal anodes. A uniform LiF/Li-M alloy functional interfacial layer based on chemical modification effectively stabilizes LMBs by inhibiting the growth of Li dendrites.
