Functional‐Group Engineering for Durable Solid Electrolyte Interphase Toward Aqueous Copper Batteries
Aqueous copper‐based batteries intrinsically suppress hydrogen evolution, offering a safer alternative to zinc systems. However, their practical deployment remains limited by poor Cu 2+ plating/stripping reversibility. Here we report a functional‐group‐guided strategy to in situ construct an organic‐inorganic hyb...
