Inert Coatings for Prevention of Ageing of NMC Cathode for Lithium-Ion Batteries - InCoatBat

Project summary

Many state-of-art cathodes for Li-ion batteries (LIBs) experience premature degradation due to surface-related instability. Protective surface coatings deposited on active cathode materials and electrodes is an effective way to improve surface stability, yet a fundamental, quantitative understanding of the working mechanisms of such coatings is still lacking. This project will develop inert protective coatings for significantly extending service life of LiNi0.83MnxCo0.17-xO2 (NMC Ni83) cathode for LIBs based on deep, quantitative understanding of underlying physical and electrochemical phenomena of electrode ageing and its mitigation. Through the contributions of four academia and two industry participants, this project will advance an innovation from fundamental research to pilot scale, demonstrating full Li-ion battery cells with improved service life, and thus helping lead the battery industry to a more sustainable use of resources, energy, and CRMs.
