CMC Binding Agent for Silicon Anodes in Li-Ion Batteries : The Impact of the Formulation

Autor: Mariama Ndour, Jean-Pierre Bonnet, Sebastien Cavalaglio, Tristan Lombard, Cedric Przybylski, Véronique Bonnet

Publikováno v: ECS Meeting Abstracts. :0471-0471

Li-ion batteries using silicon (Si) as an anodic electroactive material are promising devices that are currently being investigated. However, they have a major disadvantage, which is the large volume variation (about 300%) associated with the formati
