>With further development, we expect our new design for the lithium-air battery to also reach a record energy density of 1200 watt-hours per kilogram "With further development". Somewhat misleading title. From the published paper: >The results shown in fig. S9 indicate that this solid-state Li-air battery cell can work up to a capacity of ~10.4 mAh/cm2, resulting in a specific energy of ~685 Wh/kgcell. https://www.science.org/doi/10.1126/science.abq1347 https://www.science.org/doi/10.1126/science.abq1347 Still impressive, but not 1200 Wh/kg!
