💡 Novelty & Significance:
The novelty lies in achieving 30 mA cm–2 charge–discharge in a 5 V-class all-solid-state Li battery using Li3PO4 buffer layers, which cut interfacial resistance 45,000-fold, or a 5 nm Pt layer at the Li–Li3PS4 interface. This demonstrates that engineering electrochemically robust negative electrode–electrolyte interfaces is critical for high-power, rapid-charging solid-state batteries.
