Volvo Cars will use blockchain technology to trace the origin of cobalt used in its batteries in an effort to avoid supplies produced by children and under unethical conditions.

The commodity, an important ingredient in lithium-ion batteries, is mainly extracted in Congo, which last year produced more than two-thirds of the world’s cobalt.
