Autor: Ouyang, B, Artrith, N, Lun, Z, Jadidi, Z, Kitchaev, DA, Ji, H, Urban, A, Ceder, G

Publikováno v: Advanced Energy Materials, vol 10, iss 10

Fluorine substitution is a critical enabler for improving the cycle life and energy density of disordered rocksalt (DRX) Li-ion battery cathode materials which offer prospects for high energy density cathodes, without the reliance on limited mineral
