Abstract

The invention relates to the field of lead-acid storage batteries and discloses a gel battery and a production method thereof. The gel battery comprises a battery case, a battery cover and a plate pack arranged in the battery case, wherein the plate pack comprises positive electrode plates, composite separators and negative electrode plates which are arranged in a laminating manner; each composite separator is formed by overlapping a glass fiber separator and a microporous PE separator; a safe valve hole is formed in the battery cover; an upper reservation space is formed between the safe valve hole and the plate pack; an electrolyte injecting hole is formed in the bottom of the battery case; a lower reservation space is formed between the bottom of the battery case and the plate pack; an electrolyte injecting hole cover is arranged at a part, positioned above the electrolyte injecting hole, of the inner wall of the bottom of the battery case; at least two acid through holes are formed between the electrolyte injecting hole cover and the inner wall of the bottom of the battery case; a sealing plug is arranged in the liquid injecting hole. The gel battery disclosed by the invention can apply ordinary separators and basically keeps an original appearance of the battery; the gel battery has the advantages of simple structure, reliable sealing and easiness for production; an internalizing process and a glue filling process of the gel battery disclosed by the invention are more efficient; a prepared product is better in consistency.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to a gel battery and a production method thereof. Background technique [0002] The separators of gel batteries with a gel concentration exceeding 5% are mostly made of plastic or resin porous separators, which are complex in process and high in cost. If other common separators are used as separators for colloidal batteries, there will be two technological problems of difficulty in filling glue and forming difficulties. [0003] The application number is CN201420113592.3, and the applicant is Chaowei Power Co., Ltd. The patent discloses a colloidal battery with its own acid cycle and acid pumping structure. This structure can be applied to the internal formation of acid-absorbing separator batteries to achieve forced acid circulation on the upper and lower sides of the battery to improve formation and production efficiency. However, this patent is realized on the tank and cover, ...
