Recycling of Traction Battery Used in Electric Vehicle - Dismantling Specification

1 Scope

China's national specification for dismantling used electric vehicle traction batteries. It specifies the terms and definitions, the general requirements, the operating procedures and the storage and management requirements for the dismantling of waste vehicle battery packs, cases and modules, and it applies to used lithium-ion and nickel metal hydride traction battery packs and modules; it does not apply to dismantling individual cells. A traction battery leaving a vehicle is not scrap in the ordinary sense. It is a large, heavy assembly holding several hundred volts, containing lithium and heavy metals, capable of igniting if it is punctured or short-circuited, and worth a good deal of money for the cobalt, nickel and lithium inside it. Dismantling it is therefore three problems at once: an electrical safety problem, because the pack remains live and cannot be switched off; a chemical hazard problem, because a damaged cell vents flammable and toxic gas and a lithium fire is self-sustaining; and a materials recovery problem, because the value is in separating the streams cleanly. This standard was written as China's electric vehicle fleet reached the age at which its first batteries came out, and it was the first of a series covering the recycling chain. It requires the work to be done to a procedure, by trained people, with defined equipment, and it covers the storage of packs before and after dismantling - which matters because a warehouse of used lithium batteries is a fire risk that grows with time. Issued on 12 May 2017 and in force since 1 December 2017.

This Standard specifies the terms and definitions, general requirements, operating procedures, storage and management requirements for vehicle used waste battery packs (cases), and module dismantling work. This Standard is applicable to the vehicle used waste lithium-ion traction battery, metal hydride nickel traction battery pack (case), and module dismantling; it is not applicable to the vehicle used waste traction battery single-cell dismantling.
