In the next section, we will delve deeper into the battery cell assembly processes. Battery cell assembly involves combining raw materials, creating anode and cathode sheets, joining them with a separator layer, and then placing them into a containment case and filling with electrolyte.
Stacking battery cells into modules is a short-cycle precise process with the utmost quality demands. Defects are not accepted, and there are no second chances to get it right. The battery cells need to be firmly attached, and the joint must meet the highest requirements in terms of rigidity and crash behavior.
The second stage is cell assembly, where the separator is inserted, and the battery structure is connected to terminals or cell tabs. The third stage is cell finishing, involving the formation process, aging, and testing. Here is an overview of the production stages:
The cell assembly process begins with finished electrode reels. In pouch and prismatic cells with stacked electrodes, anodes and cathodes are separated from the electrode daughter rolls and cut to size, leaving the current collector as a tab. Details:
Our cell stack assembly solution, combining dispensing and quality monitoring systems, offers high process reliability and flexibility. Features allow for perfect tailoring and adjustment of the process parameters such as flow, pressure, temperature, and mixing ratio.
The battery materials are activated by charging and discharging, and a good SEI film is formed on the surface of the negative electrode. The performance of the SEI film determines the rate and self-discharge performance of the battery. Step 10, degassing.
