But a new series of images taken from inside mines in the Democratic Republic of Congo, where 90 percent of the world's cobalt is mined and used to make the batteries that power our tech-led lives, raise uncomfortable questions.
Cobalt is the chemical element found in almost every tech gadget that uses a lithium-powered battery on the market today - a smartphone, tablet or laptop requires a few grams of it, while an electric vehicle requires 10kg.
Apple, Microsoft, Google, Tesla and others all insist that they hold cobalt suppliers to the highest of standards, and that they only trade with smelters and refiners who adhere to their codes of conduct.
But the photos and videos that DailyMail.com can share today from some of the largest mines in Africa - where many of these suppliers get their cobalt - tell a different story.

The sudden demand for the eco-friendly vehicles, ironically driven by environmentally-conscious, is having a catastrophic effect in Congo, according to Kara.
'It’s supposed to be a green choice, getting an EV. Well it’s not green for everybody.'
Coupled with the immediate problems of overpopulated, underregulated mines is the added danger of cobalt's toxicity...<<<Read More>>>...
