When Northvolt of Sweden announced plans in September to build a $7-billion battery plant in Quebec, it marked a new high-water mark for investments in the province. It also capped a string of battery supply chain spending in Quebec over the past 18 months, adding cell production to a long list of mining and material processing sites planned, under construction or in production across the province. Paolo Cerruti, Northvolt co-founder, will steer the new project as CEO of Northvolt North America.
