Paste type positive electrode for alkaline storage battery, and nickel-metal hydride storage battery

   
   

The paste type positive electrode of the present invention contains a first active material and a second active material. The first active material comprises X parts by weight of particulate nickel hydroxide with aX/100 parts by weight of cobalt oxyhydroxide carried thereon. The second active material comprises Y parts by weight of particulate nickel oxyhydroxide, of which an oxidation number of nickel is .alpha., with bY/100 parts by weight of cobalt oxyhydroxide carried thereon. Here, all the following relations are satisfied: (1) 2.5.ltoreq..alpha.<3.0, (2) 0.01.ltoreq.(aX/100+bY/100)/(X+Y).ltoreq.0.20, (3) 0 Электрод типа затира положительный присытствыющего вымысла содержит первый активно материал и второй активно материал. Первый активно материал состоит из частей х by weight of частичный окисоводопод никеля при части aX/100 by weight of oxyhydroxide кобальта снесенные thereon. Второй активно материал состоит из частей ы by weight of частичное oxyhydroxide никеля, которого номером оксидации никеля будет alpha., при части bY/100 by weight of oxyhydroxide кобальта снесенные thereon. Здесь, все following отношения удовлетворяются: (1) 2.5.ltoreq..alpha.
