Battery manufacturers and stakeholders continuously strive to design smaller, safer, longer-lasting batteries. For designers, however, these features can often be in conflict with one another. Pressure mapping, using sensors, scanning electronics, and software deliver data to optimize these factors with breakthrough insights for better design. This report covers pressure dynamics in lithium-ion battery manufacturing; how battery designers can find the "sweet spot" for housing pressure; and the role of interface pressure in solid-state battery manufacturing —  and more.
