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.

Battery triage

Deciding what a returned battery is good for — repair, reuse, repurposing or recycling — from its history, a visual and electrical inspection and a quick state-of-health measurement. Fast, reliable triage is what makes second life economic.

End of life

The point at which a cell no longer meets its application’s requirement, conventionally 80 % of initial capacity or a doubling of resistance. It is a definition for warranties and tests, not a point where the cell stops working.

Battery recycling

Recovering lithium, nickel, cobalt, copper and aluminium from end-of-life cells and production scrap. Scrap is today’s main feedstock; vehicle returns will dominate in the 2030s, and regulation now sets minimum recovery rates.

State of health

A summary of how far a cell has aged, often expressed through remaining capacity or increased resistance compared with when it was new. By convention a cell has reached end of life at 80 % of its rated capacity.

Stationary storage

Batteries installed in a fixed place — a container at a solar farm, a cabinet in a home — to shift energy in time or support the grid. LFP cells dominate because cost per cycle and safety matter more than mass.
