Embodiment Construction

[0021] The following are specific embodiments of the present invention in conjunction with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0022] Please refer to figure 1 The alkaline dry battery of the present invention includes a positive electrode mixture pellet 3 and a gelled negative electrode 6. The positive electrode mixture pellets 3 and the gelled negative electrode 6 are separated by a separator 4. The diaphragm 4 is preferably a PAC diaphragm produced by French Moody Company. In order to ensure the isolation effect, insulating paraffin 5 is also injected between one end of the negative electrode 6 and the separator 4. The other end of the negative electrode 6 is closed by a sealing plate 7 made of nylon, a bottom plate 8, an iron plate 9 for auxiliary support, and a negative electrode current collector 10.

[0023] The outer surface of the positive electrode...

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 present invention relates to the technical field of batteries, in particular to an alkaline dry battery and positive electrode mixture pellets for alkaline dry batteries. Background technique [0002] The positive electrode adopts manganese dioxide and the negative electrode adopts an alkaline dry battery containing zinc, electrolyte and other alkaline aqueous solutions. Because of its better performance, low cost and no environmental pollution, it has become a power supply device for various equipment. [0003] Adding various active materials to the positive electrode of the alkaline dry battery to enhance the discharge and battery life 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 with publication number "CN101719547A", which add 0.1-5wt% of barium or calcium to the positive electrode pellets; another example is the Chinese patent with publ...
