Jonathan Tan took the long way to the front lines of the energy transition: UC-Berkeley chemical engineer turned field-hand in the cold of Edmonton and the deserts of Australia, installing wastewater and waste-gas recyclers—then co-founding Coreshell in 2017 after bootstrapping “the world’s cheapest battery lab” from auctioned equipment in a Richmond, California garage. Jonathan straddles business and deep tech, and he’s betting on a deceptively simple idea with huge stakes: swap today’s graphite anodes—mostly sourced from China—for a low-cost, abundant silicon alternative made with assets already operating in North America. If he’s right, EV batteries get cheaper, supply chains get sturdier, and decarbonization speeds up—not only as a moral imperative, but because the product is better for people’s lives. From rock-climbing calmly under pressure to building a team that’s stuck with him for eight years, Jonathan’s story is equal parts grit, chemistry, and clear-eyed pragmatism.
