Cathode sheet and anode sheet will be punched and stacked into pouch which will be folded with separator into cell. During Lithium Ion battery assembling process, first of all positive electrode (anode) is stacked on negative electrode (cathode), then pressed several times until electrode materials are firmly contact with each other.
The lithium batteries must be of a type that have successfully passed the UN38.3 tests and contain the necessary systems to prevent overcharge and over discharge between the batteries.
Lithium batteries do not require any form of equalization. Applying an equalization charge of 15v+ to a lithium battery will damage the cells beyond repair. The other function that lead acid chargers have is a “return to bulk” voltage. A 100% full lead acid battery’s voltage is approx 12.7v.
Quality control is a cornerstone of the lithium battery pack assembly process. At every stage, inline testing and inspection stations meticulously verify the integrity of the cell connections, ensuring that each weld or bolt meets the highest standards for electrical conductivity and mechanical strength.
The journey begins with a rigorous cell selection process, where individual lithium-ion cells undergo meticulous testing to ensure consistent quality and performance. Manufacturers measure critical parameters such as cell voltage, capacity, and internal resistance, carefully sorting and grading the cells to eliminate potential imbalances.
As the world transitions towards sustainable energy solutions, the demand for high-performance lithium battery packs continues to soar. At the heart of this burgeoning industry lies a meticulously orchestrated assembly process, where individual lithium-ion cells are transformed into powerful energy storage systems.
