Lithium-ion battery prices have dropped nearly 90% since 2008, the year that Tesla released its first electric car. Since batteries are the most expensive part of an EV, that’s a big part of the reason that the cars are finally getting close to price parity with gas cars. But lithium prices are volatile, and batteries are still relatively expensive. To help make EVs much more affordable, one new startup from a former Tesla engineer is making batteries from sodium instead.
“In short, we’re trying to make the $25K Tesla actually possible,” says Spencer Gore, CEO of the startup, Bedrock Materials, which announced a seed round of $8.5 million today.
