摘要： 由于电器的小型化和无绳化(移动电话、笔记本电脑、电动玩具和小型电动工具等),要求 配用电池小型化和高比能量化,目前MH/Ni和Cd/Ni是最有代表性的两种碱性蓄电池,作者 开发成功的高密度球形微粒Ni(OH)2[1],其填充密度比普通Ni(OH)2增加60%,使电池电容量增加30%以上.本文通过改进球形Ni(OH)2粒度和微孔结构并使用高效添加剂后,制成粘 结式氢氧化镍正极,组装MH/Ni及Cd/Ni电池,其Ni(OH)2利用率接近100%.

Abstract: The optimum technology conditions of preparation of the high density spherical Ni(OH)2 particles used as active material are reported. The size of the porous particles and crystal grain can be controlled by adjusting the micro crystal growth in order to get a tap density in 1.6 to 2.6 g/mL. Addition of a proper dopant could make the utilization ratio of Ni(OH)2 close to 100% in the pasted nickel positive electrode.

Key words: Ni(OH)2, spherical particle, preparation, property, structure, nickel hydroxide electrode
