研究磺化酞菁钴作为负极添加剂时Ni-MH电池容量、放电电压、电极的循环伏安特性和循环性能,并将其与酞菁钴比较。实验数据显示,当磺化酞菁钴添加量为3%时,Ni-MH-MH电池的放电中值电压较高,以1C倍率充放电循环300次时,容量仍保持在75%以上。
The sulfonated cobalt phthalocyanine have been used as additives of metal hydride electrode in Ni-MH battery.The effects of the properties of Ni-MH battery were studied and compared with that of cobalt phthalocyanine.Batteries with three percent of the sulfonated cobaltphthalocyanine in metal hydride electrode have excellent performances such as higher discharge voltage.They were three-quarter capacity when charged/discharged at 1C rate and 300 cycles.
