A Surface Se‐Substituted LiCo[O 2− δ Se δ ] Cathode with Ultrastable High‐Voltage Cycling in Pouch Full‐Cells

© 2020 Wiley-VCH GmbH Cycling LiCoO2 to above 4.5 V for higher capacity is enticing; however, hybrid O anion- and Co cation-redox (HACR) at high voltages facilitates intrinsic Oα− (α < 2) migration, causing oxygen loss, phase collapse, and electrolyte decomposition that severely degrade the batte...
