Method for making thin type silver electrode of silver-zinc battery

Abstract

This invention discloses one zinc silver battery thin silver electrode process method, which adopts electrochemical oxidation redaction method and uses silver foil as base board and puts it into oxidation liquid then for reduction, clearing and drying and finally in KOH liquid for charging, clearing and drying.

Description

Technical field: [0001] The invention relates to a method for manufacturing battery electrodes. technical background: [0002] As a chemical power source, zinc-silver battery has been widely used in the military since its invention because of its advantages of high specific energy, superior high-current discharge performance, stable working voltage, high charging efficiency, and high capacity and energy output efficiency. application. [0003] At present, the electrode manufacturing process of zinc-silver battery is manually spread. To ensure the uniformity of the electrode, a certain amount of active material must be used as a guarantee. large, greatly affects the output voltage and output capacity. This makes it difficult to control the thickness of the electrode within a very thin range, and the thickness of the silver electrode is generally above 0.3mm. For the zinc-silver battery used as a power source for pyrotechnics, it is a power-type battery that requires a cert...

Problems solved by technology

However, due to the electrode manufacturing technology, pyrotechnic batteries generally have the characteristics of low utilization rate of active materials, small specific energy and specific power, and large waste of materials. Moreover, the silver electrode is made of precious metal materials, which not only increases the cost, but also increases the cost. It is also a waste of national resources
