This article explains how predictive quality analytics increased production yield by 16% for battery cells. Elisa Smart Factory team conducted the project at eLab, which is the electromobility research center at the Aachen University, Germany. What’s the quality challenge in battery cell manufacturing?
Battery manufacturing is very cost sensitive to the scrap produced due to the high number of process steps and the high share of material costs. The end-of-line scrap rate (x j = A g i n g & F i n a l C o n t r o l) indicates the percentage of rejected parts identified during process step j = A g i n g & F i n a l C o n t r o l.
Calculate the product yield by adding the number of good units and reworked units available for sale. Managers evaluate the productivity of a process by measuring the number of finished products, known as outputs, against the time, materials and energy – the inputs – needed to create them. Businesses often use time as the standard input measure.
The product yield measures how many products of a saleable quality the company's processes can create. Calculate the product yield by adding the number of good units and reworked units available for sale.
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% .
The process cost share of Cell Production remains at the same magnitude (36%). Taking all the results into account, for cost reduction in optimized large-scale battery cell factories, the focus should be on the process steps Mixing, Coating & Drying, Stacking, Formation & Final sealing and Aging & Final Control.
