Design a Small DOE for Formation
Construct a compact DOE for battery formation factors and interpret why it beats OFAT.
Formation cycle time must be reduced, but first-charge current and rest time may interact through gas generation and impedance. DOE: define response, choose realistic factors and levels, protect against nuisance variation, interpret interactions Testing higher current first and shorter rest later may miss the combination that actually creates gas growth. Response Choose thickness growth after formation and DCIR after three stabilization cycles as the decision responses. The response must reflect both throughput and battery health. Cycle time alone would reward a bad recipe. Factors and levels Factor A: first-charge current at baseline or plus 30 percent. Factor B: rest time…
