Abstract

The invention relates to an alkaline dry battery and an anode mixture particle for an alkaline dry battery. The alkaline dry battery comprises an anode mixture particle and a gel cathode, wherein the anode mixture particle and the gel cathode are isolated from each other through a diaphragm. High discharging performance can be realized without adding other active elements, and a preparation process of the alkaline dry battery is simplified. Meanwhile, the continuous discharging time of a novel battery of the alkaline dry battery and a storage dry battery is prolonged, and the medium and small current intermittent discharging time of the storage dry battery in a constant-temperature environment is prolonged.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an alkaline dry battery and positive electrode mixture pellets for the alkaline dry battery. Background technique [0002] The positive electrode uses manganese dioxide, and the negative electrode uses alkaline dry batteries containing alkaline aqueous solution such as zinc and electrolyte. Due to its good performance, low cost and no environmental pollution, it has become a power supply device for various equipment. [0003] Adding various active substances to the positive electrode of the alkaline dry battery to enhance the discharge and life time of the alkaline dry battery is an important technical means to improve the performance of the alkaline dry battery. Existing patents, such as the Chinese patent whose publication number is "CN101719547A", add 0.1-5wt% barium or calcium element to the positive electrode pellets; The pellets are added with Ti(OH) 4 and TiO(OH) 2 ad...
