Optimering av en pulverdoseringsutrustning (Swedish)
Abstract [sv]

Klimatförändringar är en av de viktigaste problemen som påverkar framtida generationer. För att bekämpa detta införlivar Northvolt hållbara metoder genom hela batteriproduktionsprocessen. Ett avgörande steg i elektrodtillverkningen är slurryblandningen, vilket innebär att man kombinerar flera pulver inklusive det aktiva materialet. Det aktiva materialet doseras in i mixern med hjälp av pulverdoseringsutrustning. En omfattande studie har genomförts på pulverdoseringsutrustningen för att minska produktionstiden och förbättra kvaliteten på slurryn. Efter att ha förstått utrustningens funktioner och genomfört inledande tester på både anoden och katoden, föreslogs nya justeringar. Med de nyligen genomförda justeringarna observerades en betydande minskning av produktionstiden med 50 % i anoden och därför minskade även energiförbrukningen vid dosering. Det är viktigt att notera att stora skillnader mellan anod och katod observerades på grund av olika kemikalieanvändning. Slutligen har denna studerade framgångsrikt uppnått en minskning av produktionstid och energiförbrukning genom att optimera pulverdoseringsutrustningen som används i anod.

Abstract [en]

Climate Change is one of the main concerns affecting future generations. To combat this, Northvolt incorporates sustainable practices throughout the battery production process. One crucial step in electrode manufacturing is the slurry mixing, which involves combining several powders including the active material. The active material is dosed into the mixer using powder dosing equipment. An extensive study has been carried out on the powder dosing equipment to reduce production time and improve the quality of the slurry. After understanding the equipment’s functionalities and conducting initial tests on both the anode and cathode, new adjustments were suggested. With the newly implemented adjustments, a significant reduction in production time by 50% was observed in the anode and therefore the energy consumption during dosing also decreased. It is important to note that big differences between anode and cathode were observed due to different chemical usage. Finally, this studied has successfully achieved a reduction in production time and energy consumption optimising the powder dosing equipment used in anode.
