spent electrolyte meaning in Chinese

废电解液

All vanadium redox flow battery is a new - style and environmentally friendly energy storage battery that has many characteristics such as instant recharge by replacing the spent electrolytes , discharged at large current density , really fully discharged ( 100 % ) , increasing storage capacity easily , a theoretically unlimited life , sim - ple operation and maintenance . therefore , it is undergoing a exciting development and commercialization . however , there are still some questions to be solved during its commercialization , such as how to prepare highpurity vanadium electrolyte , to enhance its energy density and efficiency , to improve its charge / discharge performance . so it is very important for improving the perfoemance of vanadium redox flow battery and its commercialization to select adaptive electrode materials , to investigate the mechanism of the electrode reaction and to select some additives
