PURPOSE:To obtain an alkaline battery having excellent storage performance and shock resistance, stabilized intermittent discharge performance, and no stringiness of a gelled anode by using together crosslinked graft sodium polyacrylate and carboxymethylcellulose as a gelling agent. CONSTITUTION:A various concentration (wt%) of mixtures of crosslinked graft sodium polyacrylate and CMC were added to an electrolyte comprising potassium hydroxide, zinc oxide, and water to form a gelled anode 4. AA sized alkaline manganese batteries manufactured by using these gelled anodes were tested. An alkaline battery having good shock resistance and storage performance and a stabilized, easily workable gelled anode is obtained in such a way that both crosslinked graft sodium acrylate and CMC are used as a gelling agent, and 0.5-2.5wt% sodium polyacrylate, 0.5-1.5wt% CMC, and moreover 2.0wt% or more the sum of these two agents are preferable as the concentration of the gelling agent adding to the electrolyte. |
