⑴Overview of typical lead-acid battery process

Lead-acid batteries are mainly composed of battery tanks, battery covers, positive and negative plates, dilute sulfuric acid electrolyte, separators and accessories.

⑵A brief description of the process manufacturing is as follows

Lead powder manufacturing: The 1# lead powder machine, a special equipment for electrolytic lead, is oxidized and screened to produce lead powder that meets the requirements.

Grid casting: lead-antimony alloy, lead-calcium alloy or other lead alloys are usually cast into different types of grids that meet the requirements by gravity casting.

Plate manufacturing: mix lead powder, dilute sulfuric acid and additives, apply on the surface of the grid and then dry and solidify to form a raw plate.

Polar plate formation: The positive and negative plates are redox reaction with dilute sulfuric acid to produce lead oxide under the use of direct current, and then they can be used for the positive and negative plates for battery assembly through cleaning and drying.

Assemble the battery: Assemble different types and different number of plates into different types of batteries according to different requirements.

3. Introduction to grid casting

The grid is the carrier of the active material and also the conductive current collector. Ordinary open battery grids are generally cast with lead-antimony alloys, maintenance-free battery grids are generally cast with low antimony alloys or lead-calcium alloys, and sealed valve-regulated lead-acid battery grids are generally cast with lead-calcium alloys.

The first step: According to the battery type, determine the alloy lead model and put it into the lead furnace to heat and melt. After the process requirements are met, the lead liquid is cast into the metal mold, and after cooling, the mold will be trimmed and placed.

Step 2: The trimmed grid can be transferred to the next process after a certain aging. Important control parameters of the grid: grid quality; grid thickness; grid integrity; grid geometric dimensions, etc.;

4. Introduction to lead powder manufacturing

Lead powder is manufactured by Shimadzu method and Barton method, and the result is that 1# electrolytic lead is processed into lead powder that meets the requirements of battery production technology. The important components of lead powder are lead oxide and metallic lead. The quality of lead powder is closely related to the quality of the manufactured. The Shimadzu method is used to produce lead powder in my country, while the Barton method is used to produce lead powder in Europe and the United States.
