Problems solved by technology

The traditional grouting equipment is simple and open. During the grouting process, the grout splashes everywhere, the working environment is harsh, and the paste process is a suspension of lead powder, which is directly mixed with lead powder and water. The active material has a weak binding strength. Bad for battery life

Abstract

The invention relates to a lead-acid battery tube positive plate grouting method, belonging to the technical field of dynamic lead-acid battery. A grouting device is used to drive a grouting suspension into a grouting mold cavity with a pressure pump, and the grouting suspension is driven into the nonwoven drain pipe under high pressure through a second metal pipe. According to the invention, higher gravimetric specific energy and volumetric specific energy are provided, the method can meet the market demands of the tubular lead acid battery. The grouting active material is adopted in the invention, which is favorable for forming 3BS and 4BS, thereby facilitating recrystallization, oxidation and strengthening the bonding force in the curing process, increasing the initial capacity of the battery, and improving the performance and lifetime of the battery.

Description

technical field [0001] The invention relates to a grouting method for a tube-type positive plate of a lead-acid battery, belonging to the technical field of a power-type lead-acid battery. Background technique [0002] At present, there are roughly three filling methods for the positive electrode active material of tubular lead-acid batteries: powder filling, paste extrusion and grouting. Powder filling is to use the high-frequency vibration of the vibrating motor to fill the active material into the positive electrode tube. The consistency of the positive plate manufactured by this method is difficult to control, and due to the high-frequency vibration, the production noise is large and the environment is seriously polluted; The active material is mixed with the corresponding auxiliary materials and filled into the positive electrode tube with a certain pressure. This method has little environmental pollution, but it has high requirements for the formula and manufacturing p...
