【摘要】 简要介绍了钒电池研究样品的组成，工作原理及其充放电特性。结果表明，钒电池正负极活性物质的电位可以粗略代表其带电状态，且钒电池电压效率随充放电电流密度的提高而下降，充电效率则相反。钒电池大电流充放电承受能力强，特别适用于需要快速充电和大电流放电的场合。更多还原

【Abstract】 The composition,working mechanism and charge discharge characteristics of vanadium redox battery were described.Experiments showed that the potentials of electrodes could mark the state of char ging.And the voltage efficiencies declined with the increasing current density,but the coulombic efficiencies were in contrast.Vanadium redox battery can stand quick charge and discharge with high current density.更多还原
