Output

Old batteries, new Lithium

Clean

No chemicals in. No chemical waste out.

Direct

Battery-grade LiOH in a single step, no conversion loops.

Scalable

Modular stacks, from pilot to gigafactory feedstock.

€1-2 / kg LiOH

Versus €10-20 / kg market price. A ~10× cost advantage.

01 / Technology

An electrochemical process replaces the chemical-intensive stages.

A fully electrified membrane process replaces the acid- and reagent-heavy chemistry that dominates recycling today.

02 / Why now

“Lithium and rare earths will soon be more important than oil and gas.”

Ursula von der Leyen · President, European Commission · Sept 2022

The first wave of EV-era batteries reaches end-of-life this decade. Today's recycling is chemical-heavy and low-yield, and the EU's Critical Raw Materials Act now mandates domestic recycling and processing. The window opens once.
