European agreement to see Honda EV and hybrid batteries recycled or used for energy storage at end of life.
Honda has signed an agreement with Société Nouvelle d’Affinage des Métaux (SNAM) to find a second home for disused Lithium-ion (Li) and Nickel Metal Hydride (NiMH) traction batteries from Honda vehicles in Europe when they come to the end of their useful life.
Under the scheme, SNAM will collect and recycle batteries from Honda’s increasing number of hybrid and electric vehicles and either potentially prepare them for second-life renewable energy storage uses or extract valuable materials for recycling if they are not suitable for that purpose. This will ensure the traceability of end-of-life batteries and disposal in accordance with European Union environmental standards.
According to Tom Gardner of Honda Motor Europe, the requirement to manage batteries in the most environmentally-friendly way possible is growing alongside the EV market.
“Now we are able to make use of these batteries in a second life application for powering businesses or by using recently improved recycling techniques to recover useful raw materials which can be used as feedstock into the production of new batteries.”
Safe and low carbon transport is used for the collection of used traction batteries. 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 second life applications, materials such as cobalt and lithium can be extracted using hydrometallurgy techniques involving the use of aqueous chemistry. These can be re-used 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.
