Customizable materials to meet your battery needs

Halides have rapidly emerged as one of the most promising classes of solid electrolytes, offering an exceptional combination of ionic conductivity, safety, and processability. Their unique crystal structures enable fast lithium ion transport, while maintaining chemical and electrochemical stability with both high-voltage cathodes and metallic anodes. Compared to alternative materials such as oxides or sulfides, these balanced properties make halides a leading candidate for achieving the high energy density and long-term reliability required in next-generation solid-state batteries.

Oxides are stable but present moderate conductivity and are difficult to process.
Sulfides show good conductivity but present concerns with stability and safety.

Saint-Gobain halides are easy to process at low temperature, have high lithium ionic conductivity, and present no risk of hydrogen sulfide or sulfur dioxide release.

At Saint-Gobain Lithium Solutions, our expertise in halide synthesis and powder engineering allows us to precisely tailor composition, dopants, and particle morphology to meet performance targets and processing needs. Combined with our scalable manufacturing capabilities and deep understanding of solid-state interfaces, we deliver halide electrolytes that bridge the gap between laboratory innovation and industrial production.

Our research engineers at Saint-Gobain Recherche are partnering with the HELENA project, supplying halide solid electrolytes with tailored properties for the development of halide solid state batteries for electric vehicles and aircrafts. The European HELENA Project (ID 101069681) is funded by the EU through the Horizon Europe program to support the development of high-performance batteries. Saint-Gobain Recherche is one of 15 consortium partners working to create more durable, higher performing and safer batteries.

Beyond halides, our team is developing tailored oxide and phosphate chemistries or electrolyte, cathode or separator applications. Our offering, which includes materials such as LLZO and LMFP, can be customized to enhance a variety of SSB architectures. Contact our experts to discuss how we can work with your battery design.

Our engineers at Saint-Gobain Recherches are partnering with the SPRINT project, along with 16 other partners in the European Union (EU). Within the SPRINT project, which aims to develop a quasi-solid sodium battery prototype for stationary storage, Saint-Gobain Research Provence develops and upscales the cathode materials for sodium ion batteries. In particular, the team develops sodium iron phosphate as cathode material using high temperature synthesis and optimized particle design. Saint-Gobain Recherches also supplies β-alumina and alumina fillers for the electrolyte formulation. This project has received funding from the EU’s Horizon Europe Research and Innovation program under Grant Agreement No. 101191903.
