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.
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.
To complete the formation process, 3-5 cycles at 0.1 C at room temperature and 3-5 cycles at higher C-rate at higher temperature are required to control the thickness of the SEI layer. This takes several days and means the bottleneck in the battery formation process and the battery production itself.
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. There are various players involved in the battery manufacturing processes, from researchers to product responsibility and quality control.
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% .
