First-principles studies of lithium storage in reduced graphite oxide
Robledo, C.B.; Otero, Manuel; Luque, Guillermina L.; Cámara, Osvaldo R.; Barraco, Daniel Eugenio; Rojas, Mariana I.; Leiva, Ezequiel Pedro Marcos (2014-09)The present work performs a first-principles study of the lithiation of graphite oxides with low oxygencontent, which resemble reduced graphite oxide materials. The chemical nature of the Li structure formedis analysed, ... -
Intercalation stage dependence of core electronic excitations in Li-intercalated graphite from inelastic X-ray scattering
Stutz, Guillermo Eduardo; Otero, Manuel; Ceppi, Sergio Andrés; Robledo, Carla Belén; Luque, Guillermina Leticia; Leiva, Ezequiel Pedro Marcos; Barraco Díaz, Daniel Eugenio (2017)Li and C 1s core-electron excitation spectra of electrochemically prepared stage-II and stage-I lithiated graphite were investigated by means of inelastic X-ray scattering spectroscopy. The near-edge structure is discussed, ... -
Shedding light on the entropy change found for the transition stage II→stage I of Li-ion storage in graphite
Leiva, Ezequiel Pedro Marcos; Perassi, Eduardo Marcelo; Barraco Díaz, Daniel Eugenio (2017)In order to examine the controversial hypothesis put forward to explain the entropy step experimentally observed for the stage II to stage I transition for lithium intercalation in graphite, a transparent statistical ...
