Description

Technical Field

[0001] The utility model relates to the field of battery manufacturing, in particular to a battery plate with high current collection performance. Background Art

[0002] Nowadays, lead-acid batteries are widely used in fields such as automobiles, trains, tractors, motorcycles, electric vehicles, as well as communication, power stations, power transmission, instruments, UPS power supplies, and airplanes, tanks, ships, radar systems, etc.; during the production process of lead-acid batteries, the positive and negative grids of the battery need to be produced first, and then the active substances are coated on the grids, and after being roll-pressed by a roll press and heated in a drying kiln, they are cured and dried to form the positive and negative plates; the grid generally includes frame ribs, vertical ribs, and horizontal ribs, and the grid mainly serves to adhere the active substances and conduct current, and the current is conducted through the vertical ribs and horizontal ribs.

[0003] In the document with the patent publication number CN202977602U, a lead-acid battery grid, plate, and battery for improving current collection performance are disclosed, including a rectangular frame rib, horizontal ribs, and vertical ribs located inside the frame rib. The distance between adjacent vertical ribs is less than the distance between adjacent horizontal ribs. In this patent, the number of vertical ribs is increased, and the current collection effect of the battery is improved. At the same time, considering cost factors, the number of horizontal ribs is appropriately reduced, that is, the interval between horizontal ribs is increased; the interval between adjacent horizontal ribs is 10 - 11 mm; the interval between adjacent vertical ribs is 7 - 8 mm; the vertical ribs penetrate through the inside of the frame rib longitudinally, and the horizontal ribs are distributed intermittently in the inside of the frame rib transversely. The area between adjacent vertical ribs is a unit area, and the horizontal ribs in adjacent unit areas are staggeredly distributed within the same unit area, and each horizontal rib is evenly distributed, ensuring that each part of the grid has an equal supporting ability, and also enabling the active substances coated on the grid to react evenly, facilitating the smooth conduction of current, and enhancing the electrical conductivity of the battery.

[0004] However, each of its units is still a regular rectangle. When the current passes through the battery plate, it will still be multi-layered and shunted by multiple rectangular cells, and the time for the current to flow through the shortest path is still relatively long, resulting in some current being wasted on the longer path, and the utilization efficiency is still relatively low. Summary of the Invention

[0005] To solve the above problems, the utility model provides a battery plate with high current collection performance. By arranging the vertical ribs at an angle inside the frame rib, when the current passes through the battery plate, it can flow through the shortest path faster, reducing the energy loss in this process.

[0006] To achieve the above object, the technical solution of the utility model is:

[0007] A battery plate with high current collection performance, the battery plate includes frame ribs, and the frame ribs include a pair of horizontal frame ribs and a pair of vertical frame ribs; the horizontal frame ribs and the vertical frame ribs enclose a rectangular shape, and pole ears extending outward are provided on the horizontal frame ribs. It is characterized in that: a plurality of equally spaced horizontal ribs and a plurality of vertical ribs arranged at different angles with the horizontal ribs are provided inside the frame ribs, and the vertical ribs are radially distributed from one side of the horizontal frame rib to the other side of the horizontal frame rib and the two vertical frame ribs; an extended connection part is provided at the connection between the horizontal frame rib with fewer connected vertical ribs and the pole ear.

[0008] In this solution, by arranging the horizontal ribs evenly inside the frame ribs, and the vertical ribs extending radially outward from one side of the horizontal frame rib inside the frame ribs, and the adjacent vertical ribs are arranged at an angle, the current flows in from the pole ear. Compared with the equal-distance parallel arrangement of the vertical ribs, it can flow through the shortest path faster and flow out from the other end; the loss of the current during the flow in the path is smaller, and the utilization rate of the power supply is higher.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0014] Referring to "embodiment" or "embodiment" herein means that a specific feature, structure, or characteristic described in conjunction with the embodiment or embodiment may be included in at least one embodiment of the present application.
