| 摘 要： | 本文研究了甲基磺酸和硫酸混酸作为负极电解液混合支持电解质对V(III)电解液的电化学性能、稳定性、运动粘度和电池性能的影响。结果表明：以甲基磺酸和硫酸为混合支持电解质能提高V(II)/V(III)电对反应的可逆性，延迟电解液在低温下出现结晶的时间，降低电解液的运动粘度。但对电池性能有不良的影响，降低了电池库伦效率，加速了负极电解液中的钒离子向正极迁移，加快了电池容量和能量的衰减。

| Abstract: | The effects of the sulfate-methanesulfonic acid mixed electrolytes on the electrochemical performance, stability, kinetic viscosity and cell performance of the negative electrolytes are studied. The results indicate the sulfate-methanesulfonic acid mixed electrolytes could improve the reversibility of the V(II)/V(III) redox couple, delay the time for crystal at low temperature, and decrease the kinetic viscosity of the electrolytes. However, it would decrease the coulombic efficiency of battery, promote the migration of the vanadium ion, and accelerate the decay of capacity and energy. |
