In this episode of Saving the World from Bad Ideas, Mark Lynas speaks with journalist and author Nicholas Niarchos about the dirty, dangerous, and politically fraught supply chains behind lithium-ion batteries. Using cobalt mining in the Democratic Republic of Congo as a central case study, they explore how a technology essential to electrification and decarbonisation became tied to child labour, unsafe artisanal mines, corruption, colonial legacies, and weak global accountability. The conversation pushes back against a simplistic response, namely shutting down cobalt mining altogether. Niarchos argues that cobalt is a highly effective battery material and that the real problem is not the mineral itself, but the governance failures and moral outsourcing that allow abuse to persist across global supply chains.
🧠 Topics Discussed
🔋 Why lithium-ion batteries became central to the clean energy transition
⚙️ Which minerals go into modern batteries, including cobalt, copper, lithium, nickel, graphite, and phosphates
🏭 How Exxon helped pioneer lithium-ion battery research before abandoning it
🚗 Why lithium-ion batteries made modern electric vehicles viable
⛏️ Why cobalt from the DRC became so important to battery chemistry
👷 The realities of artisanal mining, including child labour, mine collapses, and extreme precarity
📱 How major brands such as Apple are tied to these supply chains, even when they claim high standards
⚖️ Why industrial mines and artisanal mines differ, but both still raise serious questions
♻️ Why recycling alone does not solve the underlying justice problem
🧪 Whether sodium-ion and other new battery chemistries will reduce dependence on cobalt
🌍 Why the goal should be fixing the supply chain, not abandoning battery technology or Congo itself
👩🏫 Guest Bio
Nicholas Niarchos is a journalist and author whose work focuses on conflict, extraction, inequality, and global supply chains. In this conversation he discusses his book on the hidden human and political costs behind lithium-ion batteries and the minerals that power the energy transition, especially in the Democratic Republic of Congo.

💬 Quote Highlights
- 💬 “The bad idea is the battery supply chain itself, which arose from a series of decisions that didn’t seem to be taken particularly consciously, but seem to be driven by avarice, essentially.” - Nicholas Niarchos
- 💬 “I have been to mines that sit directly in Apple’s supply chain and watched as people without shoes go into these mines.” - Nicholas Niarchos
- 💬 “The iPhone is the great success story for Apple. Don’t forget it. This success was built on the backs of these kinds of labor conditions. - Nicholas Niarchos
- 💬 “If we start recycling all our material, which we’re admittedly a very, very long way off from, what gets left in Congo? - Nicholas Niarchos
- 💬 “There’s no need to go to sodium. There’s no need to try and figure out new technologies... because we have the technology. The technology is the lithium ion battery.” - Nicholas Niarchos
- 💬 “The bad idea is the supply chain, not the use of cobalt in batteries.” - Mark Lynas
