Product Description
Product Introduction
Strontium Titanate (SrTiO₃) is a promising ceramic material increasingly used in the development of advanced lithium-ion batteries and next-generation energy storage systems. With its excellent structural stability, high dielectric constant, and ionic conductivity when doped, SrTiO₃ serves as an effective additive or functional layer in solid-state electrolytes, cathode coatings, and interface engineering.
In lithium battery applications, SrTiO₃ helps improve the electrochemical performance, cycle life, and safety of battery systems. It is often used as a coating material for cathode particles (such as NCM or LCO), where it suppresses side reactions with electrolytes, enhances lithium-ion transport, and stabilizes high-voltage performance. Additionally, when doped with aliovalent elements (e.g., Nb, La), SrTiO₃ can function as a solid-state electrolyte or an interface buffer layer in all-solid-state battery (ASSB) architectures.
Our SrTiO₃ is available in nano or submicron powders with high purity, narrow particle size distribution, and controlled surface properties. These features ensure uniform coating, improved conductivity, and strong chemical compatibility with battery materials.
