Gas evolution of LNMO and LNRO by operando DEMS. The first cycle voltage profiles and gas evolution rates of a LNMO and b LNRO. The total active cathode material used for the measurement was 32.9 mg LNMO (387 μmol) and 28.6 mg LNRO (253 μmol). Cells were cycled between 4.8 and 2.0 V, at a current of 10 mA g–1
