摘　　要：在强力搅拌下将KOH和Ni(OH)2混合固体粉末进行臭氧氧化,制备-γNiOOH。研究了臭氧氧化法制备-γNiOOH的工艺条件,对产物的表面形貌进行了SEM分析。测试了正极材料中添加-γNiOOH(包覆10%的Co)的LR6电池的性能。正极添加5%-γNiOOH后,电池的3.9Ω连放时间延长约40%,1.8Ω间放(放电15 s,间断45 s)次数增加约45%。γ-NiOOH was prepared by ozone oxidization of solid powder which was mixed with KOH and Ni（OH）2 under strong stirring. The process conditions to prepare γ-NiOOH by ozone oxidization method were studied. The surface morphology of the products was analyzed by SEM. The performance of LR6 battery with γ-NiOOH（eoating 10% Co） adding into positive electrode material was tested. After adding 5% γ-NiOOH into positive electrode material, the 3.9 12 continuous discharge time of the battery prolonged about 40%, the 1.8 Ω intermittent discharge times（discharge 15 s,intermittent 45 s）increased about 45 %.
