A nickel and cobalt bimetal organic framework with high capacity as an anode material for lithium-ion batteries

Abstract: The Ni–Co-BTC anode shows excellent electrochemical performance, which could be ascribed to the intercalation/deintercalation mechanism and the synergistic effect of two cations.

“…This material showed also a very high thermal stability, reported to be up 450 • C [47]. On the other hand, a mixed nickel and cobalt 1,3,5-benzenetricarboxylate (Ni-Co-BTC) was proposed as anode material for lithium-ion batteries [49].…”

“…As reported in the literature, free TMA shows characteristic bands at 3088, 1721, and 536 cm −1 which correspond to –OH stretching, –CO stretching, and –CO bending vibrations, which are not present in the synthesized MOFs. 28 The strong bands at 1615 and 1368 cm −1 are attributed to –COO asymmetric and symmetric stretching vibrations, respectively, which indicates that the carboxylic group of TMA has coordinated with the metal via a bidentate mode and comprises a polymeric structure. 29,30 The shift in peak from 1721 to 1615 cm −1 indicates that the carboxylic group of TMA is deprotonated and binds with metal, which can be further proved by the presence of a metal-ligand peak at 720 cm −1 .…”

“…Two stretching band vibrations are observed at 1375 and 1625 cm -1 , which are, respectively, assigned to the symmetric and asymmetric vibrations of the carboxylic acid functional groups in the BTC molecule. [72] The Co 3 O 4 @NC/NiO/NF sample shows two stretching vibrations at 484 and 616 cm -1 , which strongly suggests the presence of metal oxides such as Ni-O and Co-O. [73] XPS was conducted to investigate the surface chemistry, elemental composition, and electronic oxidation states of the developed materials.…”
