Nanodiamond Regulated Electrolyte Enhances Thermal, Chemical and Structural Properties for Highly Reversible Zn Metal Anodes.

ABSTRACT: Aqueous zinc-ion batteries (AZIBs) suffer from inevitable internal resistance-induced heat generation and competing hydrogen evolution, leading to high external cooling energy consumption and potential safety hazards. In this report, an electrolyte engineering strategy is proposed, involving nanodiamond (ND) additives to the commercial electrolyte. The ND particles assist in the reconstruction of the hydrogen bond network, reducing the desolvation energy of Zn²⁺, promoting the preferential deposition of (002) oriented Zn crystals, and effectively inhibiting water decomposition, Zn dendrite growth and heat-induced side reactions. Importantly, compared to commercial counterparts, ND-related electrolytes show relatively low impedance and high specific heat capacity (thermal conduct
