Problems solved by technology

[0002] The pole plate is an important part of the battery. At present, the craft pole plate is composed of several single-piece pole plates. There is a certain gap and a certain thickness of lead body connection between a single piece and another single piece. In order to ensure the strength Usually, the lead body at the joint is designed to be relatively thick, but certain problems will arise in the slicing process, such as the large vibration of the plate, which may easily cause the lead powder at the edge of the plate frame to fall off, especially in the production of raw electrodes. Plate powder removal is more serious, which reduces the input and output rate of plate production and causes a lot of cost waste

Embodiment Construction

[0014] like Figure 1 to Figure 3 As shown, the present invention includes a grid 1 and an active material body 2 attached thereto, and a connecting block 12 is arranged between the frame ribs 11 of two adjacent grids 1, the connecting block 12 is in the middle position, and the adjacent grids The frame ribs 11 are arranged symmetrically, the thickness of the connecting block 12 is 0.2-0.3 times of the thickness of the frame ribs 11, the angle a between the two frame ribs 11 is 30°-80°, the height requirement of the connecting block 0.3-0.6cm, the connecting block 12 is provided with a number of equally spaced reinforcing ribs 13 . The thickness and width of the reinforcing ribs 13 are equal, which is 0.4-0.6 times of the thickness of the frame ribs 11 .

[0015] The cross-section of the frame rib 11 is rhombus (or ellipse).

Abstract

The invention discloses a connection structure of battery technology pole plates, which comprises a grid and an active material body attached thereto, a connecting block is arranged between the frame ribs of two adjacent grids, and the thickness of the connecting block is the same as that of the frame rib 0.2-0.3 times the thickness, the angle a between the two frame ribs is 30°-80°, and several equally spaced reinforcing ribs are arranged on the connecting block. In the present invention, a thinner connection block is provided at the joint between the single plates, and several equidistant reinforcing ribs are provided at the same time, which play a role of reinforcement and prevent the overall deformation of the plates, and the thinner connection block avoids the Larger vibrations are generated during slicing, which reduces the lead powder shedding at the edge of the plate frame, especially for the production of green plates, which improves the input-output rate of plate production and saves costs.

Description

technical field [0001] The invention relates to the field of storage battery production, in particular to a battery technology plate connection structure. Background technique [0002] The pole plate is an important part of the battery. At present, the craft pole plate is composed of several single plate plates, and there is a certain gap and a certain thickness of lead body connection between a single plate and another single plate. Usually, the lead body at the junction is designed to be relatively thick, but certain problems will arise in the slicing process, such as the vibration of the plate is large, which may easily cause the lead powder at the edge of the plate frame to fall off, especially in the production of raw electrodes. Plate powder removal is more serious, which reduces the input and output rate of plate production and causes a lot of cost waste. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ...
