Ultrathin, Lightweight, and Wearable Li‐O₂ Battery with High Robustness and Gravimetric/Volumetric Energy Density

An ultrathin, lightweight, and wearable Li-O2 battery with a novel segmented structure is first fabricated by employing a “break up the whole into parts” strategy. Superior battery performance including low overpotential, high specific capacity, good rate capability, excellent cycle stability, and high gravimetric/volumetric energy density (294.68 Wh kg−1/274.06 Wh L−1) is successfully achieved even under repeatedly various deformation. As a...
