“…[10][11][12][13] Nevertheless, the wide applications of Li-metal anode in secondary batteries are still hindered by the uncontrolled lithium dendrite growth and the poor reversibility, especially when the commercial carbonate electrolytes are used. [14][15][16] Up till now, a string of methods is proposed to cope with these challenges, such as creating three-dimensional (3D) Li hosts to alleviate the uneven local current density, [17] substituting solid-state electrolyte for conventional liquid electrolytes to prevent lithium dendrite penetration, [18][19][20] introducing additives to the electrolyte to stabilize the solid electrolyte interface (SEI) films of the Li anodes, [16] constructing robust protective layers [21][22] to reduce the side reactions between the electrolyte and Li anodes, and so on. [23][24][25][26][27][28] Although these countermeasures suppress the formation/growth of the Li dendrites and reduce the side reactions between Li metal and liquid electrolytes, it remains challenging to realize the dendrite-free and high-efficiency Li depositions under high-areal-capacity conditions in conventional carbonate electrolytes, [29][30][31][32] which is one of the most critical and urgent challenges for the practical realization of Limetal batteries.…”
