Lithium metal

The ocean holds billions of tons of lithium, and scientists have just tested a new way of extracting it, with a device that takes in seawater and pumps out freshwater and lithium phosphate – plus more than enough H2 and chlorine to pay the power bill.

Scientists have made a breakthrough that overcomes a technical issue that has held back highly promising lithium-metal battery architecture, which could pave the way for batteries with as much as 10 times the capacity of today's devices.
