How sulfur could be a surprise ingredient in cheaper, better batteries

Published: February 26, 2024

The key to building less-expensive batteries that could extend the range of EVs might lie in a cheap, abundant material: sulfur. Addressing climate change is going to require a whole lot of batteries, both to drive an increasingly electric fleet of vehicles and to store renewable power on the grid. Today, lithium-ion batteries are the dominant choice for both industries.

But as the need for more batteries grows, digging up the required materials becomes more challenging. The solution may lie in a growing number of alternatives that avoid some of the most limited and controversial metals needed for lithium-ion batteries, like cobalt and nickel. One contender chemistry, lithium-sulfur, could soon reach a major milestone, as startup Lyten plans to deliver limited quantities of lithium-sulfur cells to its first customers later this year…
