ABSTRACT
Na3V1.5Cr0.5(PO4)3 cycled at 30 °C shows fast capacity decay, due to the migration of V ions into the electrolyte and the loss of V3+/V4+ redox. A low temperature of -20 °C attenuates V-ion dissolution, retains V3+/V4+ redox and improves the electrochemical performance, favorable for use in cold climates and high-altitude drones.
