Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a rate-type battery grid. Background Technology

[0002] High-rate lead-acid batteries have a higher energy density than ordinary lead-acid batteries, making them more suitable for high-current discharge scenarios. Their discharge current is typically several times that of ordinary lead-acid batteries. In terms of grid structure, they not only need to be adapted to the structural design of high-rate lead-acid batteries, but also require greater discharge current carrying capacity, thus placing higher demands on grid strength.

[0003] The grid is a major component of a lead-acid battery, serving as the current-collecting framework for the electrodes. It conducts and collects current, ensuring a uniform current distribution, and also supports the active materials, acting as their carrier. During charging and discharging, the composition of the active materials changes. Specifically, the volume of the active materials differs before and after the transformation. During discharge, the positive electrode active material PbO2 and the negative electrode active material Pb react with the electrolyte to form PbSO4, increasing its molar volume and causing the plates to expand and deform. During charging, the PbSO4 on the negative electrode is reduced to Pb, and the PbSO4 on the positive electrode is oxidized to PbO2, decreasing its molar volume and causing the plates to contract. Therefore, the grid's support prevents the active materials from detaching due to expansion and contraction. In existing technologies, conventional grid structures have relatively low structural strength, especially when subjected to uneven local stress, which can lead to localized plate deformation or even active material detachment. Summary of the Invention

[0004] The technical problem to be solved by this invention is how to improve the structure of the battery grid to improve its structural strength.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0006] A rate-capacity type solar cell grid includes a lower grid portion, an upper grid portion, lower horizontal ribs, lower vertical ribs, lower support ribs, lower reinforcing ribs, connecting ribs, upper horizontal ribs, upper vertical ribs, upper support ribs, electrode tabs, a frame, upper reinforcing ribs, a hinge portion, and flexible nails. The grid comprises a lower grid portion and an upper grid portion connected sequentially. A frame is provided on the exterior of the lower grid portion and on the upper grid portion. The lower grid portion has several lower horizontal ribs and lower vertical ribs arranged in a cross pattern. Several lower support ribs connect the lowermost lower horizontal rib to the frame. The lower part of the grating has a rigid lower reinforcing rib at the top, and several connecting ribs connect the uppermost lower horizontal rib and the lower reinforcing rib. The upper part of the grating has several cross-arranged upper horizontal ribs and upper vertical ribs, and several upper supporting ribs connect the uppermost upper horizontal rib and the frame. The upper part of the grating has a pole lug, and the lower part of the upper part of the grating has a rigid upper reinforcing rib at the bottom. A hinge is provided between the upper reinforcing rib and the lower reinforcing rib. A soft nail is connected to the lower reinforcing rib, and the soft nail passes through the upper reinforcing rib and inserts into the upper vertical rib.

[0007] Preferably, there are several connecting ribs, some of which are vertically supported and others are diagonally supported.

[0008] Preferably, the soft nails and the hinge are arranged at intervals.

[0009] Preferably, the lower and upper parts of the grid are made of a lead-calcium-tin-aluminum alloy, and the soft nails are made of polyethylene plastic.

[0010] Preferably, at least two hinges are provided, and the hinges are located in the middle of the battery grid.

[0011] Preferably, several connecting bars are also provided between the bottommost upper horizontal bar and the upper reinforcing bar.

[0012] Preferably, a number of lower horizontal ribs and a number of lower vertical ribs form a number of square holes, and a number of upper horizontal ribs and a number of upper vertical ribs form a number of square holes, with diagonal ribs provided at the diagonal positions of the square holes.

[0013] In the above technical solution, the lower and upper parts of the grating constitute the overall structure of the grating. The reason for designing the grating as a segmented structure is to increase the acceptable amount of local deformation when the local stress is uneven. The lower horizontal and lower vertical ribs are existing internal structures of the lower part of the grating, while the upper horizontal and upper vertical ribs are existing internal structures of the upper part of the grating. The frame is an integral structure between the lower and upper parts of the grating, utilizing its own toughness to withstand external forces. The lower support rib can be made of a tough insulating material to support the frame and the bottom lower horizontal rib, enhancing the structural strength of the bottom; the lower reinforcing rib is located at the top of the upper part of the grid and is used to connect with the upper reinforcing rib to form a hinge structure; the connecting rib plays a connecting and supporting role; the upper support rib is used to support the pole lug part; the upper reinforcing rib and the lower reinforcing rib are connected by a hinge, allowing the lower and upper parts of the grid to rotate within a certain range, thereby bearing a certain torque without affecting the overall structure; the soft nail is made of a tough insulating material (preferably polyethylene or polypropylene plastic) to ensure the deformation range of the hinge part.

[0014] This invention provides a rate-adjustable battery grid. The grid is designed as a segmented structure, with a resilient hinged structure at the connection points of the segments. The internal support structure of the grid is also improved, thereby effectively enhancing the structural strength and external force resistance of the grid. Attached Figure Description
