AI Technical Summary
Technical Problem
Existing flooded lead-acid batteries for traction have problems such as active material easy to fall off, small contact area with electrolyte, and expensive and inefficient production equipment.
Method used
By using lead paste overcoating and polyester heat shrink bag wrapping, positive electrode lead paste is coated on the positive grid and wrapped with polyester heat shrink bag to form a tight bond, which increases the contact area between the active material and the electrolyte and reduces the cost of production equipment.
Benefits of technology
It improves the utilization rate of active materials, extends the service life of electrode plates, reduces investment in production equipment and environmental pollution, and improves production efficiency.

Abstract
The application belongs to the technical field of lead-acid batteries, and particularly relates to a positive active plate of a flooded traction lead-acid battery and a manufacturing method thereof. The positive active plate of the flooded traction lead-acid battery comprises a positive grid with a plate lug, positive lead paste and a polyester heat-shrink bag. The positive grid is provided with horizontal ribs and vertical ribs. The positive lead paste is thickly coated in the positive grid. The polyester heat-shrink bag is wrapped outside the positive grid and the positive lead paste to bind the positive lead paste to the positive grid. The positive active plate of the flooded traction lead-acid battery avoids the falling of the lead paste by means of the over-coating of the lead paste and the wrapping of the polyester heat-shrink bag, improves the service life of the positive active plate, improves the working environment and reduces the investment cost of the production equipment. The application also provides a manufacturing method of the positive active plate of the flooded traction lead-acid battery, which is simple and easy to implement.
