McGill University Develops New Method for High-Performance Lithium-Ion Battery Materials

According to foreign media reports, a research team from McGill University has collaborated with colleagues from the United States and South Korea to develop a new method for manufacturing high-performance lithium-ion battery materials, which is expected to gradually phase out expensive and/or hard-to-obtain metals such as nickel and cobalt. The team's breakthrough lies in creating a better method for producing disordered rock salt (DRX) cathode particles, an alternative battery material. Previously, manufacturers struggled to control the size and quality of DRX particles, which contributed to their instability and made them difficult to use in production environments. The researchers addressed this issue by developing a method that produces uniformly sized, highly crystalline particles without the need for grinding or post-processing. 'Our method enables the mass production of quality-stable DRX cathodes, which is crucial for their applications in electric vehicles and renewable energy storage,' said Jinhyuk Lee, assistant professor in the Department of Mining and Materials Engineering and corresponding author of the paper.
