Electrochemical and Thermal Evolution of P2 NaMnO.

P2 NaMnO can be used as a cathode material in sodium-ion batteries. Here, the electrochemical-temperature-dependent evolution of P2 NaMnO is investigated using X-ray powder diffraction. P2 NaMnO powder under a N atmosphere shows evidence of the formation of a monoclinic C2/m phase, from about 450 °C.
