Lithium-ion batteries were first introduced to the public in a Sony camcorder in 1991. Then they revolutionized our lives. The versatile batteries now power everything from tiny medical implants and smartphones to forklifts and expensive electric cars.
And yet, lithium-ion technology still isn’t powerful enough to fully displace gasoline-powered cars or cheap enough to solve the big energy-storage problem of solar and wind power.
Dave Eaglesham, the CEO of Pellion Technologies, a Massachusetts-based startup, believes his company has made the leap beyond lithium-ion that will bring the battery industry to the next stage of technological disruption. He and his colleagues have accomplished something researchers have been struggling with for decades: they’ve built a reliable rechargeable lithium-metal battery.
