Invention Reference Number
This invention describes a new combustion synthesis route to produce high purity, high performance DRX cathodes for next-generation Li-ion batteries. Unlike present-day Li-ion cathodes (e.g., LCO, NCA, and NMC) which rely heavily on Co/Ni, DRX cathodes can attain similar energy densities while utilizing earth-abundant resources (e.g, Mn). Most prior work on DRX cathodes utilizes solid-state reaction routes which are limited to gram-scale quantities and provide little control over the powder's morphology. On the other hand, materials produced through combustion routes can be readily scaled to kg+ batches while maintaining outstanding electrochemical performance.
