A Swedish battery manufacturer Northvolt has produced its first lithium-ion battery cell featuring a nickel-manganese-cobalt (NMC) cathode produced with metals recovered through battery waste recycling. The fully recycled battery is the first step in its Revolt recycling program with which the company wants to distinguish itself from the rest of its competitors.
All the recycling and production processes were completed on a single site at Northvolt Labs in Västerås, Sweden. Specifically, the 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.
“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,” said Emma Nehrenheim, Northvolt’s Chief Environmental Officer and head of Revolt. According to Nortvolt, the electrochemical performance test of cells with recycled materials shows performance on the level of cells with freshly degraded materials.
The company now turns attention to the scaling-up of recycling capabilities to fulfill 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 in Skellefteå, Sweden, will be expanded beyond its initial design to enable...
