Reusing EV batteries

Honda hybrid and EV batteries to get a ‘second life’ in this new recycling initiative
Reusing EV batteries

Through its battery recycling partnership with SNAM (Société Nouvelle d’Affinage des Métaux), Honda Motor Europe is creating new destinies for end-of-life traction batteries from its hybrid and electric vehicles.

The pan-European arrangement will see SNAM collect the batteries and prepare them for ‘second-life’ renewable energy storage uses. Where that’s not possible, valuable materials will be extracted for recycling.

Powering businesses

Honda and SNAM have worked together since 2013 to provide traceability for end-of-life batteries and to dispose of them in accordance with European Union environmental standards.

The expansion of this agreement will see SNAM collect Lithium-ion and Nickel Metal Hydride (NiMH) batteries from across Honda’s dealer network and Authorised Treatment Facilities (ATF) in 22 countries, before analysing how suitable they are for recycling and processing them accordingly. 

‘As demand for Honda’s expanding range of hybrid and electric cars continues to grow so does the requirement to manage batteries in the most environmentally friendly way possible.

‘Recent market developments may allow us to make use of these batteries in a second life application for powering businesses or by using recent improved recycling techniques to recover useful raw materials which can be used as feedstock into the production of new batteries.’

Senior vice president at Honda Motor Europe

Reuse and recycle

On arrival, SNAM assesses which battery packs are valid for inclusion in a new energy storage device. These are then repurposed and made available by SNAM for domestic and industrial applications.

When battery cells are damaged and unsuitable for a ‘second life’, materials such as cobalt and lithium can be extracted using hydrometallurgy techniques and aqueous chemistry.

These can be reused in the production of new batteries, colour pigments or as useful additives for mortar.

Other commonly used materials including copper, metal and plastics are recycled and offered to the market for use in the production of a variety of applications.

Collection from dealerships

Dealers can arrange and request the collection of end-of-life batteries for treatment and recycling through SNAM’s dedicated online platform.

Collection can be arranged from centralised storage hubs within 15 working days, so dealers do not have to store batteries at their premises.

The agreement applies to large ‘traction’ batteries used to power motors in hybrid and electric vehicles, as opposed to smaller batteries used for ignition in petrol or diesel cars.

SNAM is supportive of Honda’s work on the eco-conscious design of future batteries, so the environmentally sound treatment of these batteries at the end of their useful life can be guaranteed.
