Abstract

The invention provides an alkaline battery capable of efficiently releasing battery capacity, comprises a battery case, an isolation element and a positive electrode ring, wherein the isolation element is formed by coaxially sleeving a plurality of layers of cylindrical isolation paper, an annular electrolyte cavity is formed between adjacent isolation papers, and the positive electrode ring is formed by mixing and pressing a solid raw material and a liquid raw material, and the liquid raw material is KOH electrolyte for the positive electrode region; KOH electrolyte for separating paper areais used in the electrolyte chamber; A negative electrode material is prepared by mixing a solid raw material and a liquid raw material, A liquid raw material is a KOH electrolyte for a negative electrode region, the concentration of KOH electrolyte for positive electrode region is smaller than that of KOH electrolyte for separating paper region, The concentration of KOH electrolyte used for separating paper region is equal to or less than the concentration of KOH electrolyte used for negative electrode region, wherein the KOH electrolyte used for positive electrode region is KOH electrolyte with mass concentration of 25-32%, and the KOH electrolyte used for negative electrode region is KOH electrolyte with mass concentration of 35-40%.

Description

technical field [0001] The invention relates to the field of battery manufacturing, in particular to an alkaline battery capable of efficiently releasing battery capacity. Background technique [0002] With the rapid development of various technologies in recent years, electrical appliances have put forward higher and higher requirements for the performance of alkaline batteries. Improving the comprehensive electrical performance of alkaline batteries, especially the discharge performance under high current or high power pulse mode has become the research direction of various battery manufacturers. In the discharge mode of high current or high power pulse, the battery polarization phenomenon will appear in the alkaline battery, and the battery polarization will cause the loss of the battery voltage, so that the capacity of the battery cannot be fully utilized. [0003] The battery polarization includes the electrochemical polarization of the electrode active material itself...
