In situionothermally synthesized redox-active carbon nitride-confined organic small molecule cathodes for ultrastable lithium-ion batteries

Abstract

Despite their high specific capacity and low cost, small-molecule organic cathodes usually suffer from fast capacity decay due to the unavoidable dissolution in the electrolytes, which largely impede their practical...

Solvent-free synthesis of organic electrodes for green sustainable energy storage

“…5f), which is the best performance of the PTCDA reported so far and the first time to use the in situ synthesized C 3 N 5 -confined strategy to improve the stability of the electrode material. 37 In addition to the molten-salt-based methods, some researchers have synthesized organic cathodes for LIBs based on the carbon–carbon coupling reaction. Because the N atoms on the pyrrole (py) ring provide electrons to form large Π-bonds, the adjacent C positions on the ring are electron-rich; therefore, the electrophilic substitution reactions tend to occur on carbons at positions 2 and 5 of the py ring.…”

C3N5-based nanomaterials and their applications in heterogeneous catalysts, energy harvesting, and environmental remediation

“…The optimised C 3 N 5 -based materials exhibited excellent reversible capacities. 132 Kim studied the electrochemical characteristics of mesoporous C 3 N 5 , which was utilised as a hybrid electrode material for Li- and Na-ion batteries in combination with molybdenum disulfide (MoS 2 ). The framework of this material is based on a triazole-based C–N structure.…”

Design of High-Performance Inorganic–Organic Hybrid Nonlinear Optical Materials Using Superhalogen Al13 and Dianhydrides

“…Three conjugated dianhydrides, pyromellitic dianhydride (PMDA), 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTCDA), and 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA), have promising applications in electronic and optoelectronic devices, such as the construction of field effect transistors, 7,8 light-emitting diodes, 9,10 optical nanocavities, 11 and metal-ion batteries. 12,13 These three conjugated dianhydrides are planar molecules consisting of two electronwithdrawing anhydride O�C−O−C�O groups attached to the opposite ends of a conjugated core of different sizes. The intermolecular interactions between NTCDA/PTCDA molecules and various metal substrate surfaces (e.g., Au, Ag, and Cu) have been explored using theoretical and experimental methods.…”
