Developments in different battery chemistries and cell formats play a vital role in the final performance of the batteries found in the market. However, battery manufacturing process steps and their product quality are also important parameters affecting the final products' operational lifetime and durability.
In addition, the production of a battery consists of many individual steps, and it is necessary to achieve high quality in every production step and to produce little scrap. In a long process chain with, for example, 25 process steps and a yield of 99.5% each, the cumulative yield is just 88% .
Since battery production is a cost-intensive (material and energy costs) process, these standards will help to save time and money. Battery manufacturing consists of many process steps and the development takes several years, beginning with the concept phase and the technical feasibility, through the sampling phases until SOP.
The protruding electrode ends of the battery cells are welded to terminals outside the casing to facilitate electrical connectivity. The next step in producing battery cells involves filling the cell assemblies with the electrolyte solution. This solution is most commonly a liquid solution of lithium salts and an organic solvent.
