Aging of the LiFePO4 positive electrode interface in electrolyte
Résumé
The evolution of lithium-containing species on the surface of grains of 500 nm LiFePO4 and 100 nm carbon-coated LiFePO4 materials during the aging process in LiPF6 electrolyte has been followed using coupled Li-7 MAS NMR, EIS (Electrochemical Impedance Sp
