Analysts estimate that the size of the EV battery industry will grow to around $70 billion by 2025, and there’s a number of innovative battery start-ups trying to grab a piece of the pie. One of these companies, Cuberg, is making lithium-metal batteries, which it says will be twice as energy dense as standard lithium-ion, and could therefore help electric vehicles become cheaper and more efficient. Because Cuberg’s tech is largely compatible with existing lithium-ion manufacturing processes, it has the potential to scale quickly. And if it does, we could see lithium metal batteries powering small planes and electric vehicles within the decade.
