Computational Study on Organic Semiconductor C60/cHBC Cocrystal for Highly Conductive Lithium Host Electrode |
초록 |
Organic materials have attracted much attention as promising active materials for high-performance lithium-ion battery electrodes due to their low cost, feasibility as a Li+ storage medium, high capability to transport electron, and the designing flexibility with electron-withdrawing/donating groups. Herein, we theoretically investigated an organic cocrystal of semiconducting fullerene (C60) and contorted hexabenzocoronene (cHBC) as a conducting agent-free organic cocrystal anode material. The crystal structure of C60/cHBC cocrystal was predicted through Monte Carlo (MC) simulation, which provided the information of the minimum-energy crystal structure from molecular structure. By performing density functional theory calculation in combination with the MC simulation, the Li storage mechanism of C60/cHBC cocrystal was found through exploring the Li+ adsorption sites and calculating the formation energy of Li-intercalated compounds. Finally, calculated voltage profile agreed well with the experimental result. |
