The next major innovation in batteries might be here – by Akshat Rathi (Quartz.com – August 7, 2018)

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.

Though other startups have for years made various claims about lithium-metal batteries, none yet have gotten past the development or testing phases; Pellion has already been selling their battery to at least one buyer since February.

Pellion’s battery can pack nearly double the energy of a conventional lithium-ion battery, making it able to, for example, double the time a drone can spend in the air. That 100% increase in energy density is a step change compared to the annual 10% or so improvement the battery industry currently averages.
