Research on the Adaptability of Vanadium Battery Stack and Electrolyte
Vanadium batteries,as a clean and efficient energy storage device,have great potential for development.Among them,the stack and electrolyte are the most important components of vanadium batteries,which directly affect the energy conversion efficiency of the DC side of vanadium batteries.However,the wide variety and differentiation of vanadium battery stacks and electrolytes in the current market have resulted in unsatisfactory energy conversion efficiency performance for some vanadium battery energy storage projects.By conducting compatibility tests on mature stack and electrolyte products in the market,analysis was conducted in four charging and discharging test modes:rated constant power mode,80％rated constant power mode,140 mA/cm2 current density constant current mode,and 170 mA/cm2 current density constant current mode.The optimal combination of vanadium battery stack and electrolyte was matched to provide reference for the research on the compatibility of battery stack and electrolyte.
