Understanding and Mitigating the Dissolution and Delamination Issues Encountered with High-Voltage LiNi<sub>0.5</sub>Mn<sub>1.5</sub>O<sub>4</sub>

In our initial study on the high-voltage 5 V cobalt-free spinel LiNi<sub>0.5</sub>Mn<sub>1.5</sub>O<sub>4</sub> (LNMO) cathode, we discovered a severe delamination issue in the laminates when cycled at a high upper cut-off voltage (UCV) of 4.95 V, especially when...
