In line with the agency, the inputs for the NMC cathode have been recovered from battery waste by means of a low-energy hydrometallurgical therapy which entails using an aqueous answer to isolate the metals and separate them from impurities.
“What now we have proven here’s a clear pathway to closing the loop on batteries and that there exists a sustainable, environmentally-preferable different to traditional mining with the intention to supply uncooked supplies for battery manufacturing,” Emma Nehrenheim, Northvolt’s chief environmental officer and head of Revolt, stated in a media statement. ”The recycling course of can get well as much as 95% of the metals in a battery to a stage of purity on par with recent virgin materials. What we want now’s to scale-up recycling capacities in anticipation of future volumes of batteries requiring recycling.”
Nehrenheim stated that because it was attainable to show the validity and effectivity of the recycling course of, Northvolt’s consideration will now flip to the scaling-up of recycling capacities to fulfil its purpose of manufacturing cells with 50% recycled materials by 2030.
To verify the trail in direction of reaching such a purpose is obvious, the corporate will develop its Revolt Ett giga-scale recycling plant, which is underneath growth subsequent to the Northvolt Ett gigafactory in Skellefteå. The target now’s to allow the recycling of 125,000 tons of batteries per 12 months.
Development of the recycling plant is about to start in Q1 2022 and operations in 2023. Incoming materials for recycling shall be obtained from two sources: end-of-life batteries from electrical autos and manufacturing scrap from Northvolt Ett.
“Along with changing into Europe’s largest battery recycling plant, Revolt Ett would be the solely large-scale facility in Europe able to recycling lithium along with nickel, manganese, cobalt and different metals,” the press transient reads. “Recovered supplies from Revolt Ett will provide neighboring Northvolt Ett cell manufacturing gigafactory with recycled metals ample for 30 GWh of battery manufacturing per 12 months (half of Northvolt Ett’s complete annual cell output).”
Along with battery metals, Northvolt expects to get well copper, aluminium and plastics from the batteries and supplies it recycles at Revolt Ett, all of which shall be recirculated again into manufacturing flows by means of native third events.
“As the electrical car revolution positive factors velocity, we ought to be conscious that some 250,000 tons of batteries will attain their end-of-life in Europe by 2030. On this, some see challenges and obstacles. At Northvolt, we see alternative,” Nehrenheim stated. “Much like how we’ve discovered novel, sustainable options for the dealing with of salt byproduct at Northvolt Ett – treating it as a precious product and never waste – the identical is true with end-of-life batteries.”
One other gigafactory
Along with Northvolt Ett, the Swedish agency announced earlier this year that it has joined forces with Volvo to construct one other gigafactory with a possible capability of fifty gigawatt-hours (GWh) per 12 months, manufacturing anticipated to begin in 2026 and site but to be determined.
The transfer would permit Volvo to equip round 800,000 autos per 12 months, whereas Northvolt will, in flip, turn into Volvo Automobiles’ unique battery cell manufacturing companion in Europe.
