Avoiding electrochemical indentations: a CNT-cocooned LiCoO<sub>2</sub> electrode with ultra-stable high-voltage cycling

Charging LiCoO2 (LCO) to above 4.5 V induces crystal cracking and seriously deteriorates the battery cycle life. Decreasing the range of the LCO misfit strain during deep de-lithiation is useful for preventing cracks, but this is not always achievable. Here, we demonstrate that the limited electroch...
