Description
Technical Field
The invention relates to the technical field of a grid of a small-sized valve-controlled lead-acid storage battery, in particular to a grid of a long-life high-power small-sized valve-controlled lead-acid storage battery.
Background
The polar plate mainly comprises a grid and an active substance, wherein lead plaster is coated on the grid, and the lead plaster is converted into the active substance to be coated on a grid framework after a series of chemical and electrochemical reactions to form the polar plate. The grid mainly plays the role of collecting current and supporting active matters in the pole plate, so that the reasonable design of the grid is beneficial to improving the corrosion resistance of the pole plate and the uniform current distribution, which is important for the service life and the high power performance of the pole plate. However, the existing small-sized valve-regulated lead-acid storage battery only has a long-life small-sized valve-regulated lead-acid storage battery and a high-power small-sized valve-regulated lead-acid storage battery.
At present, the small-sized valve-controlled lead-acid storage battery with long service life generally adopts a design scheme of thick polar plates and few plates. Because of its polar plate is thick, the grid frame and the rib of polar plate can be designed thick, can guarantee that the grid of polar plate can not cause the rib fracture because of electrolyte corrodes in the year of design, and the deformation resistance intensity is good to keep the support and the electric conductivity of grid to active material, its life can reach 3 ~ 6 years. However, since the pole plate is thick, the number of sheets that can be mounted by the battery cell is relatively small, so that the total surface area of the pole plate is small, and the high-power performance is limited.
The high-power small-sized valve-controlled lead-acid storage battery generally adopts a design scheme of thin pole plates and a plurality of plates. Because the polar plate is thin, the number of the installed single battery is large, the total surface area of the polar plate is large, and the high-power performance is improved. However, the plate thickness is thin, the plate grid frame and the ribs are also thin, the electrolyte corrosion resistance is poor, the deformation resistance strength is poor, the plate is easy to deform to cause short circuit, and the service life of the battery is influenced, so the service life of the battery is only 1-2 years generally.
