Moisture-driven discharge chemistry enables highly reversible magnesium-oxygen polymer batteries

Chem. Sci., 2026, Accepted Manuscript DOI: 10.1039/D5SC09929C, Edge Article Ju Lin, Long Jiang, Shifan Zheng, Jing Zhou, Yulong Wan, Lie Wang Magnesium-oxygen (Mg-O2) batteries are attractive for their high energy density and low cost, but their advancement is hindered by poor rechargeability, arising from the low reversibility of conventional MgOx discharge...
