The world needs lithium to power its electrical future, but getting it is a costly and dirty business. Wastewater unicorn Gradiant thinks there might be a better way, and just launched a new company to prove it.ithium is hugely important to electrifying the world’s vehicles, with just one car’s battery requiring more than 17 pounds of it. But extracting and processing the critical mineral is both costly and tough on the environment – and the United States largely relies on China for its supply.
To meet that demand, Gradiant, which cleans up wastewater on an industrial scale, is spinning out a new business, called alkaLi. Instead of mining from rock, the standalone venture plans to extract lithium from brine – naturally occurring extremely salty water found in a variety of regions – and process it for use in batteries using a technique that it developed.
The process uses resins and membranes to more easily extract the lithium from brine, then relies on its own technology to concentrate the mineral, which ultimately is precipitated into a solid for use in batteries.
