Niobium-Enhanced High-Nickel Cathodes for Longer-Lasting, Fast-Charging Li-ion Batteries
This technology introduces a one-step niobium modification that forms a LiNbO₃ surface layer and incorporates Nb⁵⁺ into nickel-rich layered cathodes (e.g., NMC 811). By simultaneously stabilizing the surface and bulk, it achieves higher first-cycle efficiency, faster charge rates, and dramatically improved cycling stability through a simple, scalable...
