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

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 the negative electrode. With regard to the capacity determining reactions at the positive electrode, related to the intercalation of anions, the influence of the carbon/graphite structure has been by far not fully understood.
