Abstract

Na₃V_1.5Cr_0.5(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.
