    摘要： Positive electrode films for a Li-secondary battery are provided. The films include composite particles including a mixed electronic ionic conductor (MEIC), a metal fluoride (MF), and optionally an electrically conductive additive comprising carbon. The films include a catholyte and a binder that are both in contact with the composite particle surfaces but not contained therein. The composite particles are characterized by a porosity of less than about 15% v/v at 25° C. Methods of forming positive electrode films for a Li-secondary battery are also provided. Methods of forming positive electrode films including annealed composite particles for a Li-secondary battery are also provided. The methods include preparing a composite including a mixed electronic ionic conductor (MEIC) including a member selected from metal oxides, metal sulfides, metal halides, metal oxyhalides, and combinations thereof, a nanodimensioned metal fluoride (MF), optionally a binder, and optionally an electrically conductive additive comprising carbon.
