In summary, Li metal anode with a robust LiCl protective layer is generated via simple in-situ chemistry. The Li metal anode with LiCl layer achieves dendrite-free morphology, forms a robust LiF-riched SEI and effectively suppresses side reactions between the electrode and electrolyte during cycling. As a consequence, LiCl@Li symmetric cells exhibit much more stable cycle performance with ultralow overpotential and offer 2.8 times longer lifetime than bare Li cells at a current density of

Li metal anode is a potential candidate for high-energy-density batteries. However, Li dendrites and the side reactions bring challenges to the application of Li metal anode. Herein, a LiCl protective layer is fabricated on the surface of Li metal anode by a facile chemistry process. Attributing to the low Li ion diffusion energy barrier and high stability of LiCl, the Li metal with LiCl layer (LiCl@Li) shows a dendrite-free deposition, forming a robust LiF-riched SEI and effectively suppresses the interfacial side reactions during cycling. The LiCl@Li anode sustains repeated plating/stripping...
