摘要: Rechargeable Na-based battery systems, including Na-ion batteries, room temperature Na–S, Na–O2, Na–CO2, and all-solid-state Na metal batteries, have attracted significant attention due to the high energy density, abundance, low cost, and suitable redox potential of Na metal. However, the Na metal anode faces several challenges, including:(1) the formation of Na dendrites and short circuiting;(2) low Coulombic efficiency (CE) and poor cycling performance; and (3) an infinite volume change due to its hostless nature …
