Gene Berdichevsky believes in batteries. As employee number
seven at Tesla, he helmed the team that designed the lithium-ion
battery pack for the company’s first car, the
Roadster, which convinced the world to take electric vehicles
seriously. A decade later,
EVs can hold their own against your average gas guzzler, but
there’s still a large trade-off between the shelf life of their
batteries and the amount of energy packed into them. If we want to
totally electrify our roads, Berdichevsky realized, it would
require a fundamentally different approach.
In 2011, Berdichevsky founded Sila Nanotechnologies to build a
better battery. His secret ingredient is nanoengineered
particles of silicon, which can supercharge lithium-ion cells when
they’re used as the battery’s negative electrode, or anode.
Today, Sila is one of a handful of companies racing to bring
lithium-silicon batteries out of the lab and into the real world,
where they promise to open new frontiers of form and function in
electronic devices ranging from earbuds to cars.
