Northvolt produces first fully recycled battery cell - Green Car Congress

Last updated Tuesday, November 16, 2021 04:37 ET , Source: NewsService

Northvolt’s recycling program, Revolt (earlier post), recently produced its first lithium-ion battery cell featuring a nickel-manganese-cobalt (NMC) cathode produced with metals recovered through the recycling of battery waste.

All recycling and production processes were completed on a single site, at Northvolt Labs in Västerås, Sweden.

What we have shown here is a clear pathway to closing the loop on batteries and that there exists a sustainable, environmentally-preferable alternative to conventional mining in order to source raw materials for battery production. The recycling process can recover up to 95% of the metals in a battery to a level of purity on par with fresh virgin material. What we need now is to scale-up recycling capacities in anticipation of future volumes of batteries requiring recycling.

—Emma Nehrenheim, Northvolt’s Chief Environmental Officer and head of Revolt

Recycled nickel, manganese and cobalt metals used in the battery cell were recovered from battery waste through a low-energy hydrometallurgical treatment which involves the use of an aqueous solution to isolate the metals and separate them from impurities.

Having proven the validity and efficiency of its recycling process, Northvolt now turns attention to the scaling-up of recycling capacities to fulfil its aim of producing cells with 50% recycled material by 2030.

To secure this, Revolt Ett, the company’s first giga-scale recycling plant under development adjacent to Northvolt Ett gigafactory...
