Abstract

Abstract : Na3 V1.5 Cr0.5 (PO4 )3 cycled at 30 °C shows fast capacity decay, due to the migration of V ions into the electrolyte and the loss of V 3+ /V 4+ redox. Abstract : Na3 V1.5 Cr0.5 (PO4 )3 cycled at 30 °C shows fast capacity decay, due to the migration of V ions into the electrolyte and the loss of V 3+ /V 4+ redox. A low temperature of −20 °C attenuates V-ion dissolution, retains V 3+ /V 4+ redox and improves the electrochemical performance, favorable for use in cold climates and high-altitude drones.
