氢过电位 meaning in Chinese

hydrogen overpotential

In this paper , we focus on the current collector to look for substitution for mercury . the metal or alloy with high over - potential of hydrogen was electroless deposited on the surface of the current collector or organic additives were used , too
本文以集电体为目标，寻找代汞物质，在集电体表面化学沉积高氢过电位的金属或合金层，或者吸附有机涂层等功能材料。
The redox of v ( ) / v ( ) , v ( ) / v ( ) couple on the graphite displayed one electron quasi - reversibility . it is proved that trace in3 + , sb3 + can inhibit cathodic hydrogen evolution during the charge process by increasing the hydro - gen overvoltage in addition that sb3 + is a stabilizing / kinetic enhancing ion . during the charge / discharge process , cross - mix and self - discharge rarely happened . the maximal energy density of the lab - level vanadium battery is 21 wh / kg . the capacity efficiency of the lab - level vanadium battery is as high as 94 . 7 %
钒电池充电末期，会发生水的电解反应，痕量铟离子的加入提高了析氢过电位，抑制了充电过程中负极氢气的析出；锑离子的加入不仅可以抑制氢气的析出，还提高了正极反应速率，增强了正极表面的稳定性。实验中得到的最高质量比能量为21wh / kg ，充放电过程中仅有极少的交叉混合和自放电发生，自制钒电池的容量效率可高达94 . 7 %
