The challenge

Why it matters

Evaporation ponds are slow, water-intensive and geography-bound, and refining capacity is concentrated in a handful of countries. Producers with good brine can still be years away from a battery-grade product.

The solution

How it works

Functionalised magnetic nano-robots capture lithium selectively out of brine, produced water or geothermal feed, are separated magnetically, release the lithium in controlled cycles and upgrade the stream toward battery-grade lithium carbonate. The process is designed for low-chemical, closed-loop operation, with the capture media returning to the front of the loop.
