Ether electrolytes exhibit better rate kinetics than carbonate ester electrolytes when used in several kinds of anode materials, especially in hard carbon (HC) for sodium‐ion batteries (SIBs). However, the mechanism causing the remarkable kinetics difference is still unclear. Here, a three‐electrode...
