Embodiment 1

[0057] like figure 1 , figure 2 As shown, a gel battery includes a battery compartment 1, a battery cover 2 and a pole group disposed in the battery compartment.

[0058] The pole group includes stacked positive plates 3 , composite separators 4 and negative plates 5 . The composite separator is formed by stacking a glass fiber separator 41 and a microporous PE separator 42 . like Figure 5 As shown, in this embodiment, the composite separator has a three-layer structure: a microporous PE separator-glass filament separator-microporous PE separator.

[0059] The battery cover is provided with a safety valve hole 21, and an upper reserved space 6 is provided between the safety valve hole and the pole group.

[0060] like image 3 , 4 As shown, the bottom of the battery tank is provided with a liquid injection hole 11; a lower reserved space 7 is provided between the bottom of the battery tank and the electrode group; the inner wall of the battery tank bottom is located ab...

Embodiment 2

[0064] like figure 1 As shown, a gel battery includes a battery compartment 1, a battery cover 2 and a pole group disposed in the battery compartment.

[0065] The pole group includes stacked positive plates 3 , composite separators 4 and negative plates 5 . The composite separator is formed by stacking a glass fiber separator 41 and a microporous PE separator 42 . like Image 6 As shown, in this embodiment, the composite separator has a three-layer structure: a glass filament separator-microporous PE separator-glass filament separator.

[0066] The battery cover is provided with a safety valve hole 21, and an upper reserved space 6 is provided between the safety valve hole and the pole group.

Abstract

The invention relates to the field of lead-acid batteries, and discloses a gel battery and a production method thereof. The colloidal battery includes a battery tank, a battery cover, and an electrode group arranged in the battery tank; the electrode group includes a stacked positive plate, a composite separator and a negative plate; the composite separator is composed of a glass wool separator and a microporous PE separator Superposed; there is a safety valve hole on the battery cover, and there is an upper reserved space between the safety valve hole and the electrode group; there is a liquid injection hole at the bottom of the battery tank; Reserve space; the bottom inner wall of the battery tank is located above the liquid injection hole, and a liquid injection hole cover is provided, 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 provided in the liquid injection hole. The colloidal battery of the present invention can use ordinary separators, basically maintain the original shape of the battery, has a simple structure, reliable sealing, and is easy to produce. The colloidal battery internalization process and glue filling process of the present invention are more efficient, and the consistency of the prepared product is better.

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 colloidal batteries with a colloid concentration exceeding 5% are mostly made of plastic or resin porous separators, which are complicated in process and high in cost. If other common separators are used as the separators of colloidal batteries, there are two process problems of difficulty in pouring glue and difficulty in forming. [0003] The application number is CN201420113592.3, and the applicant is the patent of Chaowei Power Co., Ltd. which discloses a colloidal battery with its own acid cycle and acid extraction structure. This structure can be applied to the internalization of acid-absorbing separator batteries, so as to force the battery to directly conduct acid circulation up and down, and improve the formation and production efficiency, but the patent is realized on the t...
