Blood Batteries – The Congo and The Cobalt

Google+ Pinterest LinkedIn Tumblr +

The Congo has a long, cruel history that peaked in the colonial era. Joseph Conrad wrote about the ivory trade in ‘Heart of Darkness’ in 1899. Although, thankfully by then the scourge of slave trading was largely gone. He argued there was little difference between ‘so-called civilized people in London and those described as savages’. Are ‘blood batteries’ containing cobalt echoes of Conrad’s concerns regarding imperialism?

James Conca contributed a hard-hitting piece in Forbes that he titled “Blood Batteries – Cobalt and the Congo.” In it, he says the Congo cobalt trade is the ‘perfect intersection’ between caring about the environment and concern about the social issues resulting from the ‘technological revolution of non-fossil fuels’.

There is no denying the corruption, environmental pollution, extreme poverty and child labor following in the wake of the Democratic Republic’s major income stream. And there is also no denying the undemocratic nature of the harsh regime that governs it. We could be propping the system up with every lithium battery we purchase.

Vivienne Walt and Sebastian Meyer wrote a thought piece in Fortune Magazine. They tell the tale of 15-year-old Lusaka who gets up at 5 a.m. every morning, and walks for two hours to the work station. This is where he then works for 12 hours on a cobalt mine to earn $9 ‘on a good day’. After that, he walks another two hours to get home.

Lusaka is proud of what he does as it is earning money for his family. Are there echoes of imperialism in this? Or is this just the way the world works? The western world has been on a romp since someone discovered they could make lithium-ion batteries seven times stronger by adding cobalt. This has spawned a green revolution of technology finally able to out-compete fossil fuels.

A child may have contributed to the cobalt in the blood batteries in the smartphones you see today. Perhaps one of them put bread on Lusaka’s table, or helped take years off his lifetime. Lithium battery manufacturers cannot say for certain where they source their cobalt. Should this matter?

About Author

Electricity has always intrigued me. I have been writing about batteries and energy storage for more than ten years, and have published over 4,000 articles on this website. During that time, I have researched developments across lead-acid, lithium-ion, sodium-ion, flow batteries, and emerging energy-storage technologies. My goal is to explain complex battery concepts in clear, practical language that anyone can understand. My writing career began unexpectedly after leaving the corporate world. What started as a search for a new direction gradually became a fascination with batteries, renewable energy, and the science that powers modern life. Writing may not have made me wealthy, but it has given me the opportunity to explore an industry that continues to evolve in remarkable ways.
