Embodiment 1

[0101] The lead-acid battery of the present embodiment includes a plurality of poles, and the specific structure is as follows:

[0102] The polar group includes a six-piece negative plate gate group, a partition plate and a six-sheet positive plate gate, and then achieve positive reverse folding in a certain order until the entire polar group is folded.

[0103] The six-piece positive plate gate group passes five positive and reverse folds, from the first piece, adjacent two pairs of positive electrode insulating frames are close, form a small bend, and phase There is another positive bend between the adjacent pairs of positive electrode insulation frames, wrapped a pair of negative electrode insulating frames and corresponding partitions, and in this type, finally formed three pairs of attached positive electrode insulation boxes, and A layer of silica coating paper is added to the middle of the positive electrode insulation frame to ensure the diffusion of the electrolyte; in t...

Abstract

The invention discloses a composite grid group, a lead-acid storage battery and a manufacturing method of the lead-acid storage battery, belongs to the technical field of storage batteries, and solves the problems that in the prior art, the gravimetric specific energy of the lead-acid storage battery is relatively low, and the connection structure between grids is complicated. The composite grid group comprises a plurality of insulating frames which are arranged in a laminated manner, a plurality of lead wires and a plurality of insulating wires, wherein the lead wire is in the shape of a continuous snake-shaped line and comprises transverse sections and bent sections which are alternately arranged and connected with each other, the transverse sections transversely penetrate through the insulating frames, the bent sections are located on the side surfaces of the insulating frames, and the insulating wires longitudinally penetrate through the insulating frames. The lead-acid storage battery comprises the composite grid group. The composite grid group, the lead-acid storage battery and the manufacturing method of the lead-acid storage battery can be used for supplying power to electric equipment.

Description

Technical field [0001] The present invention belongs to the field of battery cells, and more particularly to a composite sheet gate group, a lead-acid battery, and a method of fabricating it. Background technique [0002] The poles of the lead-acid battery typically include a plurality of grid groups, for example, including a positive plate gate group and a grid group. [0003] In the prior art, the plurality of grids in the grid group are set independently and connected through a bus discharge, resulting in the structure and fabrication process of the grid gate group. Inventive content [0004] In view of the above analysis, the present invention is intended to provide a composite sheet gate group, lead-acid battery, and a method of fabricating the same, and solve the problem of complicated structure and production process of the prior art middle plate group. [0005] The object of the present invention is mainly achieved by the following technical solutions: [0006] The prese...
