Abstract:Recently, graphite has been recognized as a potential negative electrode for sodium (Na)-ion batteries via the use of a solvent cointercalation mechanism. However, nearly all works exploring this mechanism have focused on glymes, which are stable for reversible cointercalation. Herein, we demonstrate branched diamines, such as 1,3-diaminopentane, as alternative cointercalating solvents showing initial capacities up to 130 mAh/g for graphite in Na cells. X-ray diffraction indicated a reversible and smaller expa… Show more
