A kind of zinc-silver battery negative plate drying process

Abstract

The invention discloses a drying process for the negative plate of zinc-silver battery. After the negative plate is formed, it is put into a cleaning tank for cleaning and washing, taken out from the cleaning tank, and the excess water on the plate is absorbed by filter paper, and then the plate is put into In the 99.9% zinc plate, wrap the plate with filter paper and separate it from the zinc plate; then put it into the muffle furnace for drying, the temperature is adjusted to 200°C~400°C, and the drying time is controlled within 40min~60min After the drying is completed, wait until the temperature of the plate drops to room temperature, and store it in a dry container. The beneficial effects of the present invention are: 1. Effectively prevent the oxidation reaction of the negative plate in the air and improve the discharge quality of the plate; 2. After the plate is dried, the flatness of the surface of the plate is better than the normal production level; 3. Improve the quality of the plate. Drying time shortens the production cycle, improves product quality and reduces production costs.

Description

technical field [0001] The invention relates to a process for making negative plates of zinc-silver batteries, in particular to a drying process suitable for processing the negative plates of zinc-silver batteries. Background technique [0002] Zinc-silver storage batteries have high mass specific energy and volume specific energy; high specific power can be discharged at a high rate, and the capacity does not drop much when discharged at high current; the battery discharge voltage is stable, self-discharge is small, and it has good mechanical strength. , can still be widely used in some occasions, especially in military technology and aerospace technology as a starting and emergency power supply. For military technology, due to the particularity of the occasion, the rated weight of the battery is relatively high compared to the energy requirement, and the conditions are harsh. , which requires the battery’s electrical performance to be maximized, especially the electrical p...

[0003] At present, the negative plate of this kind of battery is made of special zinc powder and other materials mixed with paste. After the plate is formed, it is washed with water and dried in the air. Now, the natural drying process is mostly used. The negative plate is very easy to react in humid air. The discharge performance and storage performance of the battery have a great influence
