Abstract:

Lithium(Li) metal has high theoretical specific capacity, a low reduction potential, so is one of the ideal materials for the anode of lithium batteries. During the long-term cycling, however, lithium metal has problems such as interface deterioration and serious energy loss due to lithium dendrites growing. The optimization of interface reaction between lithium metal electrodes and electrolytes is a significant research direction. In the paper, the hazards caused by lithium dendrites was outlined, as well as comprehensively reviewing methods adopted to solve this problem from analysis and inhibition of lithium dendritic deposition, including the formation and protection mechanisms of solid electrolyte interface, surface modification, three-dimensio-nal lithium anode, liquid/solid electrolytes, etc. Besides, the advantages and disadvantages of methods above are summarized, and research prospects to lithium metal batteries is expected in the energy field simultaneously.

Key words: Lithium metal battery, Lithium dendrite, Solid electrolyte interface, Electrolyte
