Abstract:
Hydrazine-embedded heterocyclic compounds with dimeric dimethylacridine (1b), carbazole (2b), and phenothiazine (3b) skeletons were applied to cathode active materials of rechargeable lithium organic batteries, and the performance of the batteries was evaluated. The charge/discharge curves exhibited clear plateaus in the high voltage range of 3.3-3.7 V. The capacities of the plateau regions were comparable to the calculated capacities corresponding to the one-electron redox of the molecules. The amount of the active compound 3b could be increased up to 30 wt% in the electrode composite, and fast charge/discharge performance was also observed.
