Gradient-morph LiCoO2 single crystals with stabilized energy density above 3400 W h L−1
The cycling stability of LiCoO[subscript 2] under high voltages (>4.5 V) was plagued by hybrid anion- and cation-redox (HACR) induced oxygen escape and uncontrolled phase collapse. With DEMS and in situ XANES mapping at the NSLS-II, we demonstrate that oxygen escape triggers irreversible transfor...
