Detailed density functional theory calculations show that strong hydrogen bonds are formed between BT water molecules in WiSCE. Thus, strongly confined by BT, particularly within interlayers, which significantly inhibits greatly improves stability. Compared state‐of‐the‐art “water‐in‐salt” electrolytes, can provide higher full‐cell level with substantially reduced cost, promising for design next‐generation high‐performance AZIBs. This work provides new direction developing cost‐competitive AZIBs as alternatives grid‐scale energy storage.
