Combustion Synthesis of DRX Cathodes

This invention introduces a scalable combustion synthesis method to produce high-performance, manganese/titanium (Mn/Ti)-based disordered rocksalt (DRX) cathodes for Li-ion batteries. This approach overcomes the limitations of traditional solid-state methods, which are challenging to scale and provide limited control over material properties. By leveraging earth-abundant materials, this method supports the production of DRX cathodes with high energy density, making it a valuable solution for next-generation batteries used in everyday electronics. 

Description

The combustion synthesis of Mn/Ti-based DRX cathodes offers a new pathway for creating high-energy density cathode materials for lithium-ion batteries. Traditional cathode production methods, such as solid-state routes, are limited in scalability and precision, often producing inconsistent results. This new method allows for bulk production (kilogram-scale) while maintaining tight control over the chemistry of the cathodes. Additionally, the process reduces energy requirements and improves the electrochemical performance of DRX cathodes. By utilizing lower-cost, earth-abundant materials like manganese, the invention addresses the growing demand for sustainable battery solutions without sacrificing performance. 

Benefits

• Scalable production: Enables large-scale production of high-purity cathode materials. 
• Cost-effective: Utilizes earth-abundant materials, reducing reliance on expensive and scarce metals like cobalt and nickel. 
• Tight chemical control: Allows for precise control of the material’s chemical composition, improving reproducibility and performance.
