Battery passport

A digital record for each electric-vehicle and industrial battery, required in the EU from 2027, holding its composition, carbon footprint, due-diligence data, state of health and repair history, accessible by QR code.

End-of-line testing

The final measurements on every finished cell — capacity, internal resistance and open-circuit voltage — used to reject faulty cells and sort good ones into matched grades.

ISO 9001, ISO 14001 and ISO 45001

The three certifiable management-system standards that cell and pack makers are expected to hold: ISO 9001 for quality, ISO 14001 for environmental management and ISO 45001 for occupational health and safety. Automotive suppliers add IATF 16949, the industry’s quality-system standard built on ISO 9001.

Yield

The fraction of started material that ends as saleable cells. New plants often run at 60–80 % and mature ones above 95 %; because materials dominate cell cost, each point of scrap is expensive.
