Researchers at McGill University have developed a new method to make high-performance lithium-ion batteries without using costly nickel or cobalt. By using a molten salt process, they can produce uniform, highly crystalline disordered rock-salt (DRX) cathode particles that boost battery stability and performance. In tests, the new material kept 85% of its capacity after 100 charge cycles, more than double older DRX methods. This advance could make next-generation batteries cheaper, cleaner, and easier to scale for electric vehicles and renewable energy storage.
