Company Overview

CellCircle is a German company founded in 2022 as a spin-off from the Fraunhofer Institute for Silicate Research ISC. Based in Randersacker, Germany, the company specializes in innovative lithium-ion battery recycling, efficiently separating and regenerating functional materials for direct reuse in new battery production. Their mission is to establish sustainable battery cell recycling systems across Europe, promoting eco-friendly practices and reducing dependence on raw material imports.

Battery Technology

Their process directly yields high-purity functional materials such as NMC, LTO, and carbon particles from used lithium-ion batteries without complex intermediate steps. This method offers superior energy efficiency, cost reduction, and lower CO₂ emissions compared to conventional recycling, and is adaptable to emerging technologies like sodium-ion batteries and fuel cells.

Products

A scalable recycling system that regenerates finished functional materials—NMC, LTO, and carbon—for immediate use in new battery cell manufacturing, delivering high material purity and reduced energy consumption.

Recent Projects

In June 2023, presented recycling solutions at SPRIND VENTURE VISION in Leipzig; initiated collaboration with Federal Agency SPRIND in November 2024; recognized as Bavaria’s best energy start-up in November 2024.
