Abstract

The invention relates to the field of a lead acid storage battery, and discloses a solid acid battery with an absorbed partition plate and a high-efficiency internal formation process of the solid acid battery. The solid acid battery with the absorbed partition plate comprises a battery groove, a battery cover and a pole group, wherein the pole group is arranged in the battery groove and comprises a positive pole plate, the absorbed partition plate and a negative pole plate which are laminated, a safety valve hole is formed in the battery cover, an upper reserved space is arranged between the safety valve hole and the pole group, a liquid injection hole is formed in a bottom part of the battery groove, a lower reserved space is arranged between the bottom part of the battery groove and the pole group, a liquid injection hole cover is arranged on an inner wall of the bottom part of the battery groove and above the liquid injection hole, at least two acid through holes are formed between the liquid injection hole cover and the inner wall of the bottom part of the battery groove, and a sealing plug is arranged in the liquid injection hole. With regard to the battery employing the absorbed partition plate, the original appearance of the battery is basically maintained, and the battery is simple in structure and better in sealing performance and is easy to produce. The internal formation process and a glue pouring process of the solid acid battery with the absorbed partition plate are more efficient, and the fabricated product is better in consistency.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to an adsorption-type separator solid-acid battery and a high-efficiency internalization process thereof. Background technique [0002] The separator of the lead-acid battery has two functions, one is "separation", the function is to prevent the risk of short circuit between the positive plate and the negative plate in the middle of the battery, the common materials of the separator with only this function are PVC, phenolic resin, PE, etc. The second is "absorption", which acts as a porous medium to absorb and fix the electrolyte solution. Common materials for separators that have both functions include glass fiber cotton, porous ceramics, and glass felt. [0003] During the internal formation process of lead-acid batteries, the first type of separator using the above two separators is normally formed in a "rich liquid" state, only a small amount of electrolyte infiltrates the sep...
