Carbon-Loaded Flexible Electrode Films for Li-O2 Cells: Preparation, Porosity, Homogeneity and Electrochemical Characterization

Autor: Matthieu Courty, Christine Surcin, Caroline Gaya, Dominique Larcher, Alejandro A. Franco

Porous (up to 70 vol. %) self-standing flexible carbon/polymer (Ketjen Black / PVdF-HFP) film electrodes are produced by leaching out a plasticizer-porogen agent (DBP = DiButyl Phtalate) from precursor films (80% ³ DBP w% ³ 40%). Textural analysis

Multi-Scale Modeling and Experimental Characterization of Charge Process of Li-O2 Batteries: Impacts of Particle Size and Cycling History

Autor: Yinghui Yin, Caroline Gaya, Amangeldi Torayev, Vigneshwaran Thangavel, Dominique Larcher, Alejandro A. Franco

Publikováno v: ECS Meeting Abstracts. :134-134

Li−O2 batteries have attracted significant attention due to their high theoretical capacity up to ~3000 Wh/kg, but they are still facing many challenges which avoid their penetration in practical applications. Their high charging voltage, which usu
