Embodiment 1
[0094] The lead-acid battery of the present embodiment includes a plurality of pole groups, and the specific structure is as follows:
[0095]The pole group includes a six-piece negative grid group, a separator and a six-piece positive grid group stacked together, and then folded front and back in a certain order until the entire pole group is folded out.
[0096] The positive electrode grid group of six consecutive pieces is folded forward and backward five times. Starting from the first piece, two adjacent pairs of positive electrode insulating frames are bent together, forming a positive small bend, and the opposite A positive large bend is formed between two adjacent pairs of positive insulating frames pasted together, wrapping a pair of negative insulating frames and corresponding separators, and so on, finally forming three pairs of positive insulating frames pasted together, and A layer of silica-coated paper is added in the middle of each pair of positive electrode ins...

The invention discloses a lead-acid storage battery and a manufacturing method thereof, belongs to the technical field of storage batteries, and solves the problems of low gravimetric specific energy and complicated plate group structure and manufacturing process of the lead-acid storage battery in the prior art. The storage battery comprises a positive electrode insulating frame, a positive electrode lead wire, a negative electrode insulating frame and a negative electrode lead wire, the positive electrode lead wire is in the shape of a continuous snake-shaped line, the transverse section of the positive electrode lead wire transversely penetrates through the positive electrode insulating frame, and the bent section of the positive electrode lead wire is located on the side face of the positive electrode insulating frame; the negative electrode lead wire is in a continuous snake-shaped line shape, the transverse section of the negative electrode lead wire transversely penetrates through the negative electrode insulating frame, and the bent section of the negative electrode lead wire is positioned on the side surface of the negative electrode insulating frame; and the positive grid group and the negative grid group are oppositely inserted. The lead-acid storage battery and the manufacturing method thereof can be used for supplying power to electric equipment.
Description
technical field [0001] The invention belongs to the technical field of accumulators, in particular to a lead-acid accumulator and a manufacturing method thereof. Background technique [0002] As a secondary battery, lead-acid battery has many advantages such as low price, high voltage, strong temperature adaptability, safety and reliability, and recyclability. It is widely used in starting, starting and stopping, energy storage power supply, power drive, backup power supply and Various fields such as peak-suppression and valley-filling of electric power. [0003] In the prior art, the pole group of a lead-acid battery usually includes a plurality of sequentially stacked negative plates, separators and positive plates. Multiple negative plates are independently arranged and electrically connected through bus bars, and multiple positive plates are independently set and connected through bus bars. Electrical connection leads to complex structure and manufacturing process of th...
