Improving battery gigafactories is crucial for global electrification, with facilities potentially producing enough cells for an EV every minute. The immense manufacturing data, especially from the initial formation process that creates the SEI, is key. Utilizing data-driven process control and voltage-based metrics allows for establishing an electrochemical fingerprint, ensuring performance, lifetime, and safety through smart specifications and tighter tolerances. Analyzing full cell voltage data via DVA/ICA reveals vital thermodynamic and kinetic properties non-destructively. Careful data handling is essential to balance throughput and reliability, with voltage analysis complementing other metrology methods. Overcoming data interpretation complexities through reproducible methods will unlock smarter battery manufacturing.
