In the production process of lead-acid batteries, multiple stages directly affect the battery's performance, lifespan, and reliability.
Guangdong Kajie Group Co., Ltd. has consistently focused on the effective enhancement of production processes, implementing a series of improvements and optimizations in plate manufacturing, assembly, formation, and housing and sealing processes, reflecting an unwavering pursuit of battery performance excellence. In this issue, we will discuss the plate manufacturing process.

• Fine Tuning of Lead Powder Oxidation Degree and Particle Size
• The Critical Impact of Lead Paste Density Uniformity on Lifespan
• Additive Ratio: A Scientific Balance Between Strength and Conductivity
Lead paste serves as the foundation for the active material of electrodes, with its composition and structure directly determining battery capacity and cycle life. The oxidation degree and particle size distribution of lead powder must be precisely controlled (typically 60%-80% oxidation). Insufficient oxidation results in poor bonding of the active material, while excessive oxidation affects porosity.
Uneven lead paste density can cause localized shedding of active material on the plates, shortening battery life. Insufficient sulfuric acid content may result in lower initial capacity, while excess levels can accelerate grid corrosion.

• Accurate control of temperature, humidity, and time
• 3BS/4BS crystal: enhances the anti cycling ability of the electrode plate
• Hidden dangers of insufficient solidification: looseness and capacity decay
Kaijie batteries strictly calculate the ratio of additives (such as sulfuric acid, short fibers, lignosulfonates) to adjust the strength and conductivity of the electrode plates.
Curing is the core step in forming the crystal structure of the electrode plate, which determines the strength and electrochemical performance of the active material.
Insufficient solidification can lead to loose electrode plates, detachment of active substances, causing battery short circuits or capacity degradation. Unreasonable crystal structure (such as a low 3BS ratio) can reduce the cycling resistance of the electrode plates.
