New insights into electrochemical anion intercalation into carbonaceous materials for dual-ion batteries: Impact of the graphitization degree

Autor: Uta Rodehorst, Patrick Münster, Martin Winter, Tobias Placke, Andreas Heckmann, Olga Fromm

Publikováno v: Carbon. 131:201-212

Within the past 5 years, dual-ion batteries and in particular their all-carbon/all-graphite versions, the dual-carbon or dual-graphite batteries, have received rising interest due to the use of carbonaceous active materials for both, the positive and
