Used electric vehicle batteries could be the Achilles’ heel of the transportation revolution—or the gold mine that makes it real.

THIS SUMMER, DIRK Spiers, a tall, rumpled Dutchman-turned-Oklahoman, got a heads-up from General Motors about more problems with the Chevrolet Bolt. Over the previous year, the car model that had once been celebrated as GM’s grand victory over Tesla—the United States’ first truly mass-market electric vehicle—had begun to look more like a slow-motion disaster. Bolts were being recalled because of a series of rare but destructive fires sparked when drivers left their cars charging overnight. GM had traced the problem to flaws in the lithium-ion battery cells manufactured by South Korea’s LG Chem.

Now the automaker was expanding the recall to all 141,000 Bolts sold worldwide since 2017. Fixing them would be a massive operation. Unlike the toaster-oven-sized lead-acid batteries inside most gas-powered vehicles, the lithium-ion battery pack inside the Bolt runs the full wheelbase of the car and weighs 960 pounds. It contains hundreds of battery cells that are delicate and finicky. When taken apart for repairs, they can be dangerous, and incorrect handling can lead to noxious fumes and fires.

Spiers was a natural person to call for help. His relationship with GM had begun 11 years earlier, when he buttonholed the company’s head of development for an earlier electric vehicle, the Volt, about GM’s plan for the batteries when they broke or died. It turned out GM didn’t really have one. Spiers turned that opening into a business that now handles the logistics of dead and dying EV batteries from every major carmaker that sells in the US, except Tesla. Spiers New Technologies takes flawed batteries and transports, tests, and—when possible—disassembles, fixes, and refurbishes them. “We get our hands dirty,” Spiers says.
