The engineering of single-ion conductors (SICs) is a promising strategy to stabilize the anode/electrolyte interface in zinc-ion batteries. However, the commonly employed single-ion conductive solid or quasi-solid electrolytes often lead to a significant reduction in overall ionic conductivity, thereby impeding ion diffusion kinetics. Here, we propose a compromise strategy that effectively balances ionic conductivity and ion transference number. Specifically, a single-ion conductive interpenetrating polymer networks (IPNs) with phase-functional decoupling is developed solely on the anode side, while a liquid electrolyte is retained on the cathode side. This design facilitates a high ion transference number (0.84) while maintaining the ionic conductivity at an optimal level (12.1 mS cm
