Abstract

The invention relates to the field of lead-acid batteries, and discloses an adsorption-type separator solid-acid battery and a high-efficiency internalization process thereof. The solid-acid battery with adsorption type separator includes a battery tank, a battery cover and an electrode group arranged in the battery tank; the electrode group includes stacked positive plates, adsorption separators and negative plates; the battery cover is provided with a safety valve There is an upper reserved space between the safety valve hole and the pole group; there is a liquid injection hole at the bottom of the battery tank; there is a lower reserved space between the bottom of the battery tank and the pole group; the inner wall of the battery tank bottom is located at the injection hole A liquid injection hole cover is arranged above the liquid hole, and at least two acid holes are formed between the liquid injection hole cover and the bottom inner wall of the battery tank; a sealing plug is arranged in the liquid injection hole. The invention aims at the battery using the adsorption separator, basically keeps the original appearance of the battery, has simple structure, better sealing performance and is easy to produce. The internal formation process and the glue pouring process of the solid-acid battery with the adsorption type separator of the present invention are more efficient, and the prepared product has better 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...
