氧化锌在镍氢动力电池中的应用
Application of zinc oxide in MH/Ni power battery
摘要
Abstract
MLNi3.9 Co0.6 Mn0.3 Al0.3-hydrogen storage alloy electrode was prepared by using zinc oxide (ZnO) as additive.The initial open circuit voltage of battery prepared by adding 0.5% ZnO was 1.20 V.When cycled in 1.0-1.6 V with 0.2 C,the initial discharge specific capacity was 291.7 mAh/g and capacity retention rate was 95.88% after 100 cycles.Compared to the blank MLNi3.9 Co0.6 Mn0.3 Al0.3 electrode,it was improved 0.39 V,31.6 mAh/g,5.70%,respectively.200 Ah MH/Ni power battery was made under the condition of the electrode,the shelved voltage of adding zinc battery was more than 1.20 V and initial discharge capacity reached to 200 Ah when cycled in 0.8-1.6 V with 0.2 C,while the blank battery reached to the rated capacity after 3 cycles.The addition of ZnO did not affect standard cycle life,charge retention and capacity recovery of battery.关键词
