PCC Thorion Establishes Polish Subsidiary to Advance Industrial Production of Silicon-Carbon Anode Materials

Duisburg / Poland, June 18, 2026 – PCC Thorion GmbH, an innovative developer and producer of silicon-carbon (Si/C) composite materials for lithium-ion batteries, announces the establishment of PCC Thorion Sp. z o.o. in Poland. This strategic step marks a major milestone in the company’s path toward industrial-scale production and commercialization of next-generation anode materials.
The newly founded subsidiary will serve as the central vehicle for preparing the construction of a first manufacturing facility for Si/C composites in Poland. Planning activities are progressing rapidly to ensure that increasing customer demand from Europe and international markets can be met in the near term.

With the establishment of PCC Thorion Sp. z o.o., the company is actively contributing to the development of a resilient and competitive European battery ecosystem. The European Union has identified the reduction of critical raw material dependencies—particularly on graphite imports—as a key strategic priority.

Today, graphite dominates as the anode material in lithium-ion batteries, but its supply chain is highly concentrated outside Europe and increasingly seen as a strategic vulnerability.

Silicon-based anode materials offer a transformative alternative:

• significantly higher energy density
• faster charging capability
• improved overall battery performance

PCC Thorion’s Si/C composite technology combines silicon’s exceptional capacity with the structural stability of carbon, addressing key technical challenges such as volume expansion and cycle life.

A core advantage of PCC Thorion’s product is its drop-in capability:

The Si/C composite materials are designed to be directly integrated into existing battery manufacturing processes without requiring major process changes.

This enables:

• fast industrial deployment
• minimal retooling efforts for cell manufacturers
• accelerated time-to-market for advanced battery technologies

The solution is specifically optimized for high-power and high-energy applications, including electric mobility, aviation, and stationary energy storage.

By building production capacity in Poland, PCC Thorion reinforces its commitment to a fully European supply chain—from raw materials to finished anode material.

As part of the PCC Group, the company benefits from access to sustainably produced silicon based on renewable energy, contributing to a significantly reduced CO₂ footprint compared to conventional solutions.

This approach provides customers with a reliable, transparent, and geopolitically resilient supply alternative, addressing growing concerns around global dependencies.

PCC Thorion’s flagship project ProHiPerSi was designated in 2025 by the European Commission as a Strategically Important Raw Materials Project under the Critical Raw Materials Act.

The designation highlights:

• the project’s contribution to Europe’s security of supply
• its technical maturity and scalability
• its alignment with EU sustainability and industrial goals

The establishment of PCC Thorion Sp. z o.o. represents a key implementation step toward realizing this strategic project and accelerating its industrial deployment.

With its new presence in Poland, PCC Thorion is laying the foundation to:

• rapidly scale industrial production of Si/C anode materials
• serve global customers with high-performance, sustainable solutions
• and play a leading role in the next generation of battery materials

PCC Thorion is thus making a clear statement: combining technological leadership with a strong commitment to “Made in Europe.”
