文摘
Solvents influence on crossover and capacity decay was studied for vanadium NARFBs. Nafion and low permeability Nafion/SiO2 was evaluated in two solvent environments. A method to estimate species crossover was developed from self-discharge tests. 84/16 vol% AC/1,3 DO mixture improved capacity retention and efficiency. Crossover rate variation was due to membrane changes in the different solvents.
