镍电极快速充电研究

Study on fast charging of nickel electrodes

讨论了镍电极中活性物质成分与粘结剂配方对ＭＨ－Ｎｉ电池１Ｃ快速充电性能的影响。结果表明，当镍电极中活性物质成分调整至Ｎｉ（ＯＨ）２为７５％、导电剂为１５％，添加剂为６．５％，粘结剂为３．５％时，并采用ＰＴＦＥ与ＣＭＣ混合型粘结剂（配比为ＰＴＦＥ∶ＣＭＣ＝１∶１），制造出来的发泡式镍电极的ＭＨ－Ｎｉ电池１Ｃ充放电性能较好，且１Ｃ充放电循环寿命达１５０次以上。

The properties on fast charging of Ni MH batteries which were improved by adjusting the active compositions of nickel electrodes and binder prescriptions have been discussed.It has found that Ni MH batteries which used foamed nickel electrodes as its anodes whose active composition had been adjusted (Ni(OH) 2:75%,additives:6.5%,Ni powders:15%,binders:3.5%) and which had used miscellaneous binders of PTFE and CMC (PTFE:CMC=1:1) have good properties and long operating life of more than 150 cycles at 1C charge and discharge rates.
