Storage battery positive pole plate and manufacturing method thereof

Abstract

The invention discloses a storage battery positive pole plate and a manufacturing method thereof. The storage battery positive pole plate comprises a plate body and the upper and lower surfaces of the plate body are provided with glass fiber mat layers. Each one of the glass fiber mat layer has thickness of 0.2+/-0.03mm. The manufacturing method comprises 1, filling a continuously produced grid band with lead paste to obtain a pole plate band main body, 2, pasting glass fiber mats to upper and lower surfaces of the pole plate band main body to obtain a pole plate band, 3, compressing the film-coated pole plate band so that the glass fiber mats are fully bonded to the pole plate band main body, 4, cutting the pole plate band to obtain pole plates, 5, stacking the cut pole plates, 6, putting the stacked pole plates in a curing chamber and carrying out curing and drying and 7, carrying out natural cooling. The surface of the positive pole plate is provided with the netted porous glass fiber mat layer so that contact between an electrolyte and an active substance is not influenced, the glass fiber mat layer effectively prevents plate active substances on the plate body from falling off, positive and negative pole plate short circuit caused by the fallen active substances is avoided and a lead acid battery service life is effectively prolonged.

Description

technical field [0001] The invention belongs to the field of lead-acid batteries, and in particular relates to a battery positive plate and a manufacturing method thereof. Background technique [0002] With the rapid development of the global economy, traditional fossil energy (such as coal, oil, natural gas, etc.) has become increasingly unable to meet people's production and living needs. Such non-renewable resources are being depleted, and the extreme use of such energy has caused serious global environmental pollution problems. In view of this, for the sustainable development of human society, all countries in the world are committed to the development and promotion of renewable clean energy. As the oldest chemical power source, lead-acid batteries are currently widely used in many fields such as national defense, aviation, communications, and transportation. The technological progress of lead-acid batteries has promoted the development of information, communications, a...

AI Technical Summary

Problems solved by technology

During the use of lead-acid batteries, the falling off of the active material on the positive plate will seriously affect the use effect of the battery. In severe cases, the falling active material will cause a short circuit between the positive and negative plates, which will directly lead to the scrapping of the battery
