KURZ as a strategic partner for innovative coatings for battery cells and systems
Battery technologies - such as lithium-ion batteries - are essential due to their high energy density and durability. In order to reduce dependence on imports and at the same time raise environmental and social standards, key production steps must take place in the EU. This is where KURZ comes into play with its Energy Technologies division: our expertise in thin-film technology and central location in Europe make us an important strategic partner for these coatings. And also one with international expertise - through our joint venture with Horizon.

Joint venture for innovative battery technology in Europe
Two-in-one: Horizon-Kurz New Material Technology GmbH, based in Fürth, Germany, combines the expertise of Chinese technology company Horizon with that of thin-film technology specialist LEONHARD KURZ. The aim of the partnership is to significantly improve the safety, service life and performance of lithium-ion batteries - especially for the stationary storage market and electromobility in Europe. To this end, the company is developing highly functional coating solutions for separator films for lithium-ion batteries. Efficient, reliable, sustainable - and with decades of coating expertise.
The heart of modern lithium-ion batteries
Separator films are key components of lithium-ion batteries. They separate the anode and cathode, but are also permeable to ions - a decisive factor for the performance and safety of batteries. Targeted film coatings can significantly optimize thermal stability, mechanical strength and adhesion and thus overall performance.
Sustainable and precise coating made in Europe
Technologically, ecologically and economically convincing: ultra-modern processes ensure precise and even application of the coatings. The joint venture focuses on the greatest possible conservation of resources and economical use of materials. The coated films are suitable for all standard cell formats and thus enable a wide range of applications.
Separator films
- State-of-the-art base film
- Ceramic coating on one or both sides
- With and without adhesion promoter layer

Innovations in development
Fire protection for flammable materials
IGNIRIT® offers reliable protection against the spread of flames. The binder for coatings has a flame-retardant effect with ecological responsibility and makes a significant contribution to safety in e-mobility and other industries.
Heat protection for battery systems and vehicles
Our heat protection film combines high mechanical strength with heat resistance of up to 250°C with direct contact and up to 1,000°C without direct contact. The protection of machine parts for the automotive or aircraft industry is possible.
Digital Battery Passport
Starting in 2027, manufacturers and distributors of a number of industrial and traction batteries will be required to provide a battery passport.
Our digital product passport system includes comprehensive information about the battery’s origin, production, composition, and end-of-life handling and Comply with EU Battery Regulation 2023/1542 – with a ready-to-use, scalable solution from KURZ.
You profit from:
- Easy integration with your existing systems (e.g. ERP, BMS, PLM)
- Efficient operations through centralized data
- Verifiable sustainability for ESG reporting
- Market advantage, transparency, built-in product authentication
- Track and trace capability for aftermarket and returns
- Predictable costs and scaling from single units to full production
- Expandability for added values: traceability, brand protection, or digital maintenance
