PURPOSE:To prevent leakage of an electrolyte and improve preservation performance by dispersing a filler with the specific particle diameter in the low molecular weight polyamideamine as a sealing compound between a negative electrode sealing plate and an insulating packing. CONSTITUTION:This alkaline storae battery disperses and inserts fine powder fillers of 0.1mu or less such as silicon oxide, titanium oxide, silicon nitride, and alumina, in the low molecular weight polyamideamine with the amine value of 80-400 and the number mean molecular weight of 10,000 or less as a sealing compound between a negative electrode sealing plate 1 and an insulating packing 2. As a result, the alkaline storage battery with excellent leakage characteristics can be obtained. |
