摘要： PURPOSE:To stabilize the performance of a battery against strong shock such as drop and vibration by using a high water-absorbing resin made of starch- polyacrylate as the gelling agent of a gelled negative electrode in an alkaline battery. CONSTITUTION:In a gelled negative electrode 4 mainly comprising an alkaline electrolyte, a gelling agent, and negative zinc powder, starch-polyacrylate which is a high water-absorbing resin is used as the gelling agent. Movement or coagulation of zinc particles dispersed in the gelled negative electrode 4 is restrained even it strong shock such as drop of a battery, and even if the gelled negative electrode is moved by strong shock, it is recovered to the original state. Contact between zinc particles dispersed in the gelled negative electrode 4 and contact between zinc particles and a negative current collector are kept well. Even if strong shock is applied, good current collecting effect is kept same as the initial state and performance of the battery is stabilized.
