Recycling of lithium-ion batteries : A comparison of metal extraction methods (English)
Abstract [sv]

Rapporten identifierar befintliga återvinningsmetoder för litiumbatterier och analyserar två avmetoderna på djupare nivå, en hydrometallurgisk metod och en pyrometallurgisk metod.Analysen är avgränsad till att utvärdera metoderna med Sverige som systemgräns och utifrånett ekologisk hållbarhets- och ekonomiskt lönsamhetsperspektiv. Verktyg som använts är enSWOT-analys som baseras på en litteraturstudie och intervju där kriterier identifierats. Dekriterier som valts för att utvärdera ekologisk hållbarhet är elkonsumtion, behov avkemikalier samt farligt avfall. De ekonomiska lönsamhets aspekterna har utvärderats medavseende på återvinningsmetodernas kapacitet, återvinnings- och reningsgrad,investeringskostnader samt metodkomplexitet. Analysen resulterar i att denpyrometallurgiska metoden är mest lämpad för Sverige i dagsläget eftersom den har högkapacitet och överensstämmer med befintlig infrastruktur. Andra slutsatser som dragits är attval av återvinningsmetod är kontextbaserat med stor vikt vid geografiskt område och tillgångtill batterimaterial.

Abstract [en]

The report identifies existing recycling methods for lithium batteries and analyzes two of themethods, a hydrometallurgical method and a pyrometallurgical method, on a deeper level.The analysis is limited to evaluating the methods with Sweden as a system boundary basedon environmental sustainability and economic profitability. Tools used are a SWOT analysisbased on a literature study and interview where criteria were identified. The criteria chosenfor evaluating environmental sustainability are energy consumption, the need for chemicalsand hazardous waste. The economic profitability aspects have been evaluated with respect tothe capacity of the recycling methods, recovery and purification, investment costs andmethod complexity. The analysis concludes that the pyrometallurgical method is mostsuitable for Sweden today as it has high capacity and conforms with existing infrastructure.Other conclusions drawn are that the choice of recycling method is context-based with greatemphasis on geographical location and access to battery material.
