a Discharge/charge voltage ranges and capacities of selected aromatic organic molecular crystals (DMQ, 2,5-dichloro BQ, 1,5-dichloro AQ, 9,10-PQ, PTCDA, and PT in 1M CaCl2 electrolyte. The typically reported inorganic electrodes including CaxCuHCF32, KxNiFe(CN)633, are also listed for comparison. b XRD pattern of PT powder (red cross) and the Rietveld-refined XRD pattern (blue line). c Perspective view of a PT supercell observed from a axis and c axis. d SEM image. e HRTEM image and SAED pattern. f FTIR spectrum of PT materials.
