Description
Technical Field
The invention relates to the field of lead-carbon battery devices, in particular to a novel lead-carbon battery grid.
Background
The lead-acid storage battery has undergone the development process of nearly 150 years, and the power battery has important commercial value due to high reliability, low cost, excellent high and low temperature performance and over 98% recovery rate, and still occupies a major market share in the field of low-speed electric vehicles (such as electric mopeds, electric motorcycles, and the like) up to now. However, the conventional lead-acid power battery cell (12V20Ah) has short cycle life (80% DOD, 300 cycles), high cell weight (7.2kg), low power and poor high and low temperature performance (in southeast asia and northern cold regions in china), and thus, the application development of the low-speed power vehicle with high safety, low cost and great commercial value is limited.
At present, most of design versions of lead-acid power battery grids are based on a design scheme of a transverse rectangular grid, and the design scheme aims to solve the problems of grid current transmission and corrosion resistance, but still follows the requirements of 2009 edition of national standard, and the weight of the grids is not corrected too much, because the specific surface area and the resistance of the grids are closely related, and the weight of the grids (particularly positive grids) is increased, so that the corrosion time can be delayed. The solution strategy is to improve corrosion by adding a conductive polymer coating layer on the surface of grid ribs, or change the transmission path of current by adjusting the structure of the ribs in the grid, reduce the weight of the grid and improve the corrosion of the grid. Although the method can improve the corrosion resistance of the grid, the coating process of the grid in actual production is complex, the large-scale industrial production difficulty and the cost are high, the gravity casting yield of the grid in actual production is low, a continuous punching and continuous rolling grid production line needs to be purchased, and the price advantage of a low-cost lead-acid power battery and a lithium ion battery is reduced.
However, the existing composite material lead storage battery grid has some defects in the use process, the overall stability of the battery grid is poor, the deformation phenomenon is easy to occur, and the loosening phenomenon is easy to occur due to the fact that the device is connected to the lug, so that the use effect of the battery grid is poor. In addition, the existing storage batteries are required to have sufficient capacity, the lead-calcium alloy grid is soft in quality, the grid ribs are sparse, the rib structure is thin, or casting is not uniform in the casting process of the grid, so that the ribs are exposed in the later pasting process or deform during charging and formation, and the capacity of the originally designed battery is often not achieved.
Disclosure of Invention

Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, a novel lead-carbon battery grid comprises a frame and a reticular structure located in the frame and comprising transverse ribs and vertical ribs, wherein the reticular structure in the frame comprises two rows arranged in parallel, and the two rows of reticular structures are connected and fixed through connecting ribs; crossed reinforcing ribs are arranged on the diagonal line of the cuboid formed by the two rows of net structures;
in the production and processing process of the storage battery, the grid is used as a carrier and a conductor of the lead plaster, the lead plaster can be used as a polar plate only after being filled and coated on the grid and cured and dried, the polar plate is the core of the lead-acid storage battery, and the grid is just like a framework and has direct influence on the strength and the service life of the whole polar plate.
When the polar plate is produced, the lead plaster can be filled into the net-shaped structures, and the lead plaster can be better fixed through the two rows of net-shaped structures which are arranged in parallel, so that the effect of preventing the lead plaster from falling off easily is achieved;
the connecting ribs are made of copper materials or iron core coated aluminum materials;
the reinforcing rib strip is made of a copper material or an iron core coated aluminum material;
when processing, the connecting ribs and the reinforcing ribs are all closer to the outside than the net-shaped structure, the whole net-shaped structure can be completely wrapped by lead plaster during filling, even if the filling is finished, parts of the connecting ribs and the reinforcing ribs are exposed outside, and the grid can not be corroded and the service life of the battery can not be influenced because the connecting ribs and the reinforcing ribs are made of metal materials which do not react with electrolyte.
In a specific embodiment, in order to increase the contact area between the transverse ribs and the lead plaster, the transverse ribs and the vertical ribs are arranged in a wave shape;
through holes are formed in the middle parts of the transverse ribs and the vertical ribs at intervals, so that lead paste can penetrate through the transverse ribs and the vertical ribs when lead paste is poured, the lead paste is combined with the transverse ribs and the vertical ribs more tightly and firmly, and the service life is prolonged;
in another specific embodiment, the connecting ribs and the reinforcing ribs are in a hollow hole structure, and through holes are formed in the middle of the connecting ribs and the reinforcing ribs at intervals, so that lead plaster can enter the connecting ribs and the reinforcing ribs when lead plaster is poured, the bonding tightness between the lead plaster and the grid is further enhanced, and the lead plaster is prevented from falling off;
the above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
