Problems solved by technology
[0002] The existing battery plates include grids and active materials. The grids are pre-opened grid molds, including horizontal and vertical ribs and frame ribs. The lead-calcium alloy or lead-antimony alloy is melted at high temperature and then passed through a huge casting process. The high-temperature melting of lead alloy is a high-power-consuming process, and some lead dust and lead fume are discharged into the air, polluting the air and causing great impact on the physical and mental health of production workers; active substances: Cut the lead strip into small pieces first, and ball mill it into lead powder with apparent density and oxidation degree meeting the requirements through a lead powder machine. Fill the prepared lead paste into the grid of the grid, completely cover the horizontal and vertical ribs of the grid, and then send it into the curing room for 50-60 hours of curing and drying to make a pole plate
This process is anti-lock, energy-consuming and not environmentally friendly. Lead dust and lead fumes are also discharged into the air, polluting the air and affecting the physical and mental health of production workers.

Embodiment Construction
[0026] like figure 1 , figure 2 As shown, a battery pole plate includes a positive pole plate and a negative pole plate. Both the positive pole plate and the negative pole plate are composed of tabs, a pole plate matrix, and an active material. The upper part of the pole plate matrix is connected to the pole tabs. The surface of the plate substrate is covered with active materials.
[0027] The materials of the tabs and the plate base are 1# electrolytic lead with a purity of 99.99%, and do not contain calcium, tin, aluminum, cerium and other rare earth metal components. The tabs and the base of the pole plate are made of metallic lead by casting or stamping. Preferably, the tabs and the plate base are formed by punching lead strips or lead plates. Preferably, the tabs and the pole plate base are formed by rolling and pressing lead strips or lead plates made of pure lead, and then cutting through a punching die.
[0028] As a preference, a transition fillet is designed...

Abstract
The invention relates to a storage battery pole plate, which includes a tab, a pole plate base, and an active material. The plate matrix is punched by lead strips or lead plates, and the active material is generated by electrochemical corrosion, which is generated by the plate matrix through the combination of early small current, mid-term excessive discharge and reverse charging; the said The thickness of the lug is greater than that of the plate base; the active material is naturally generated by electrochemical corrosion. The invention greatly simplifies the production process, reduces energy consumption and environmental pollution in the production of the pole plate, effectively prevents the active material of the pole plate from falling off, and improves the performance and service life of the storage battery.
