Organic cathode materials are plagued by their low cycle stability and poor electronic conductivity, even though they have attracted increasing attention in the context of lithium-ion batteries (LIBs). Herein, a coordination polymer cobalt-hexaazatriphenylene hexacarbonitrile (Co(HAT-CN)) is prepared via a facile solvothermal method, which is composed of the redox-active HAT-CN linker and the Co(II) ion center. The fabricated material shows excellent structural stability and high conductivity Moreover, graphene oxide (GO) is introduced as a substrate, and in-situ loading of Co(HAT-CN) on its surface shows enhanced cycling stability. For Co(HAT-CN)/GO, a high specific capacity of 204 mAh g-1 can be retained even after 200 cycles at a c.d. of 40 mA g-1 in a voltage window of 1.2-3.9 V. Ex situ and in situ analyses are applied to probe the reversibility of the pyrazine redox-active center during the cycling process and the lithium storage process. D. functional theory calculations reveal that the high conductivity of Co(HATCN) should be ascribed to the narrow LUMO-HOMO gap (0.61 eV), and strong binding of lithiated mols. In the experiment, the researchers used many compounds, for example, Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile (cas: 105598-27-4Computed Properties of C18N12).
Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile (cas: 105598-27-4) belongs to quinoxaline derivatives. Compounds possessing quinoxaline derivatives were bestowed with a variety of significant biological properties such as antiviral, antimalarial, anticancer, DNA intercalation, DNA duplex stabilization, and many others. Quinoxaline and its analogues may also be formed by reduction of amino acids substituted 1,5-difluoro-2,4-dinitrobenzene (DFDNB),One study used 2-iodoxybenzoic acid (IBX) as a catalyst in the reaction of benzil with 1,2-diaminobenzene.Computed Properties of C18N12
