Definition

Cobalt is a hard, lustrous metal essential to most lithium-ion battery cathodes, superalloys and catalysts. The Democratic Republic of the Congo supplies over 70% of mined cobalt, with artisanal and small-scale mining accounting for an estimated 15–30% of Congolese output — a segment documented to involve child labour and hazardous working conditions.

Overview

What it means

Electrification of transport has made cobalt a flashpoint where the energy transition meets human-rights due diligence.

How it is used

The metal appears on the US Department of Labor's List of Goods Produced by Child Labor; downstream companies trace it via initiatives such as the Responsible Minerals Initiative's Cobalt Reporting Template.

Why it matters

Demand growth, supply concentration and documented abuses make cobalt a defining case for responsible sourcing and battery-chemistry innovation.
