The global race to develop batteries for electric cars is reaching deep into the pine forests of central Sweden, where a dormant graphite mine is getting a new lease on life.
Woxna, situated about 160 miles (259 kilometers) north of Stockholm, was mothballed in 2001 amid a slump in prices. Now, a Canadian company called Leading Edge Materials Corp. is preparing to revive operations.
Though graphite has grabbed fewer headlines than other battery components like lithium and cobalt, whose prices have surged in recent months, the carbon material makes up a large part of the raw material costs.
