Description

Technical Field

[0001] The utility model relates to the technical field of storage batteries, in particular to a grid of a sealed micro valve-regulated lead-acid storage battery. Background Art

[0002] The grid is the main component of the lead-acid battery. It is the collector skeleton of the electrode and the carrier of the active material. It can support the active material, conduct and collect current, and make the current evenly distributed.

[0003] When the lead-acid battery grid is in use, the contact area between the grid and the active material is small, the contact internal resistance is large, the conductivity is poor, the large current discharge performance is poor, and the cycle life is insufficient.

[0004] In order to overcome the above-mentioned defects, prior art 1 (Chinese patent with publication number CN218548483U and application date 2022-09-20) provides a battery grid and a battery that can effectively increase the contact area between the grid and the lead paste, and reduce the contact internal resistance between the grid and the active substance of the lead paste. Therefore, the capacity of the battery using this grid can be effectively improved, and the high current discharge capability of the battery can also be improved.

[0005] Patent 2 (publication number CN213878156U, application date: September 16, 2020) discloses a battery grid. This utility model utilizes vertical ribs on either side of the horizontal diamond-shaped mesh ribs, and transverse connecting ribs between the vertical ribs on the side closest to the diamond-shaped mesh ribs and the vertical frame ribs, thereby enhancing the overall grid's resistance to deformation and creep. The use of transverse connecting ribs reduces the battery's internal resistance, facilitating high-current discharge.

[0006] Both existing technologies 1 and 2 can improve the conductivity of the grid during use, but during use, there is a material swelling phenomenon during the discharge process of the lead-acid battery. For example, the lead oxide at the positive electrode will be converted into lead sulfate with a larger molar volume during the discharge process, resulting in an increase in the volume of the lead paste, which will squeeze the grid and cause the grid to deform, affecting the later use of the grid.

[0010] An internal structure capable of improving the strength of the grid body is provided in the grid body cavity. The internal structure comprises vertical ribs which are arranged in an array between the two ends of the grid body cavity.

[0011] Furthermore, the tops of the limiting ear plates are each provided with limiting circular holes, and the limiting posts are snapped into the limiting circular holes one by one.

In combination with the reinforcement mechanism, the anti-deformation effect of the grid body itself is more reliable.

[0021] 4. By utilizing the arc-shaped notches and load-bearing holes on the reinforcement block, when the grid is subjected to force, the force can be better alleviated and reduced. Compared with other lead-acid battery grids, it is more solid and not easy to break, which greatly extends the battery life.
