Investing in Jälle

We turn graphite-rich residues from lithium-ion battery recycling into graphene oxide in Tallinn, and supply it as an additive to makers of coatings, concrete and composites. We're building Jälle with investors who want critical materials kept in use.

WHY JÄLLE

What we're building

01

A waste stream as feedstock

Our raw material is graphite-rich residue from lithium-ion battery recycling, which today largely goes to landfill or incineration.

04

Rooted in materials research

Our founders' work grew out of years of materials research at Estonia's National Institute of Chemical Physics and Biophysics.

02

Products customers can test now

GOAqua dispersion and Pure GO and Pure RGO powders, with samples and trial quantities available on request.

05

Made in Tallinn, shipped worldwide

We produce graphene oxide in Tallinn, Estonia, and ship samples and trial quantities to customers worldwide.

03

Large markets for additives

Coatings, concrete and composites, where small additions can change how a product performs.

06

Process know-how we keep

We adapt purification, oxidation and exfoliation to recovered graphite, and keep the details as confidential know-how.

PROGRESS

Where we are now

01

Pre-seed raised

€2 million in July 2025, with grant support from Enterprise Estonia and the Environmental Investment Centre.

02

Scaling to pilot

We supply development and trial quantities today and are scaling graphene oxide production to pilot scale.

03

Trials with customers

We supply samples and run trials with formulators of coatings, concrete and composites enhancing their products.
