不饱和标准电池常用多孔性有机物隔膜或塞片来固定两极物质,隔膜材料中部分有机物溶入电解液,并在电极表面建立吸附层,从而阻化电极反应,使电池产生较大的滞后现象。采用低密度聚乙烯圈固定夏布的膈膜设施,能使溶入电解液的有机物减少到非常有限的程度。这种电池的滞后现象很小,充、放电后电动势能较迅速恢复,电动势年平均下降值为38μV,稳定性很好。不饱和标准电池的电动势和内电阻值的温度系数为: (dE_t)/(dt)=[a+2b(t-25)+0.0216(t-25)~2-0.0002(t-25)~3]×10~(-6)伏/度式中a=5.28-5642(E_(25)-1.018000) b=0.051-40.81(E_(25)-1.018000) (dR)/(dt)=R_(25)[-0.0317+0.0015(t-25)]欧姆/度
Unsaturated standard batteries commonly used porous organic septum or plug to fix the bipolar material, part of the membrane material dissolved in the electrolyte into the electrolyte, and the electrode surface to establish an adsorption layer, thereby deteriorating the electrode reaction, the battery has a greater hysteresis. The use of low-density polyethylene ring diaphragms fixed diaphragms, can dissolve into the electrolyte of organic matter reduced to a very limited extent. The hysteresis of this battery is very small. After charging and discharging, the electromotive force can recover rapidly. The average annual emf drop value is 38μV, and the stability is good. The temperature coefficient of electromotive force and internal resistance of the unsaturated standard battery is: (dE_t) / (dt) = [a + 2b (t-25) +0.0216 (t-25) ~ 2-0.0002 (t-25) ] × 10 ~ (-6) volts / degree where a = 5.28-5642 (E_ (25) -1.018000) b = 0.051-40.81 (E_ (25) -1.018000) (dR) / (dt) = R_ (25 ) [-0.0317 + 0.0015 (t-25)] ohm / degree
