Jälle Technologies Secures €2M In Pre-Seed Round

The company focuses on recovering valuable materials from end-of-life batteries, especially converting waste graphite into next-generation carbon-based materials like few-layer graphene.

With battery waste in Europe expected to exceed 230 kilotonnes by 2030, Jälle addresses the urgent need for more efficient recycling. Their technology offers high recovery rates for lithium while also upcycling discarded graphite into strong, conductive and flexible materials used in advanced applications.

Founded by scientists from Estonia’s National Institute of Chemical Physics and Biophysics—including Kerli Liivand, Martin Jantson, Reio Praats, Erki Ani, and Ivar Kruusenberg—Jälle is driven by the mission to solve the battery waste challenge at scale.

The €2M round includes grant support from Enterprise Estonia (EIS) and the Environmental Investment Centre (KIK), along with early-stage equity from Kiilto Ventures, 2C Ventures, and angel investors Andrus Purde and Priit Viru.

According to Erki Ani, CEO of Jälle Technologies, while the whole world is geared towards electrification, energy storage needs are inevitably on the rise.

“What happens with these batteries once they’ve reached the end of their life? With Jälle, we are looking a few steps ahead of the curve to be ready for the “tidal wave of dead batteries.

By achieving very high battery recycling efficiencies and enabling advanced applications through our graphene-like materials, we contribute to addressing Europe's critical raw materials challenge.

We’re extremely glad that we have such investors who share our vision. It’s not just about funding, it’s about working together to take our technology from the lab to industry.”

Matti Rönkkö, Managing Partner at Kiilto Ventures—the corporate venture arm of Finnish chemical company Kiilto, known for championing sustainability and circular economy solutions—highlighted the strong potential of Jälle’s scalable technology.

“Jälle Technologies’ vision to turn battery waste into valuable resources through cutting-edge recycling is exactly the kind of scalable, sustainability-driven innovation we want to champion.”

Hendrik Reimand Founding Partner at 2C Ventures shared “Battery recycling is no longer optional. Jälle’s team combines deep technical expertise with a clear commercialisation strategy, making them exactly the type of founder-led, high-impact company that we strive to support from our fund.”

The new funding will support the expansion of pilot-scale production, help validate Jälle’s proprietary processes at a larger scale, and enable the company to grow its expert team in Estonia, with recruitment already underway.
