Synergistic Sr2+ Doping and MXene Engineering of Layered δ‐MnO2 Toward High‐Performance Aqueous Zinc‐Ion Batteries

Small, EarlyView.
Sr‐doped δ‐MnO2/Nb2C composites are engineered for aqueous zinc‐ion batteries, utilizing Sr2+ doping and conductive Nb2C to enhance structural stability and ion transport. The optimized cathode delivers a 407.3 mAh g−1 capacity and excellent cycling, driven by a reversible Zn2+/H+ co‐insertion mechanism, making it suitable for flexible electronics ...
