Organic Species-Intercalated Vanadium Oxide for Sodium-Ion Battery: Mixed-Anion Coordination Effect, Enhanced d-p Orbital Hybridization, and Topotactic Phase Conversion Induced by N-Substitution

Inorganic Chemistry, Journal Year: 2023, Volume and Issue: 62(49), P. 20105 - 20119

Sodium-ion battery (SIB) is a reasonable alternative to lithium-ion (LIB) in the field of grid-scale energy storage systems. Unfortunately, development appropriate cathode material bottleneck SIB. In present work, (p-TQ)-VO, formulated as (p-TQ)0.2V2O5·0.38H2O, was synthesized based on facile hydrothermal reaction V2O5 and methylhydroquinone (p-HTQ). And when replaced by VN, (p-TQ)-VN, (p-TQ)0.22V2(O/N)5, prepared instead. The (p-TQ)-VO sample displays good electrochemical performance SIB cathode. (p-TQ)-VN shows much higher capacity at small current density, it can maintain structural integrity with partial topotactic phase transformation into NaxV2O5 during discharge/charge process. A series characterizations reveals successful intercalation p-TQ layered (001) lattice spacing 13.7 10.7 Å, respectively. terminal oxygen (Ot) atoms from V-O-V layer have been substituted N atoms, which boost orbital hybridization V 3d Ot 2p, shorten V-Ot bonds c-axial direction, elongate V-O ab plane compressed {VO4N2} octahedra, giving rise mixed-anion coordination effect. As result, enhanced electron densities around facilitate affinity toward inserted Na+ ions, leading conversion NaNO2/NaNO3. Moreover, density functional (DFT) calculations reveal that N-incorporation improve conductivity richer molecular levels, resulting multistep redox reactions capacity.

Regulating V₂O₅ Layer Spacing by a Polyaniline Molecule Chain to Improve Electrochemical Performance in Salinity Gradient Energy Conversion

Langmuir, Journal Year: 2024, Volume and Issue: 40(42), P. 22462 - 22476

Published: Oct. 10, 2024

Salinity gradient energy is a chemical potential between two solutions with different ionic concentrations, which also an ocean at the junction of rivers and seas. In our original work, device "activated carbon//(0.083 M Na2SO4, 0.5 Na2SO4)//vanadium pentoxide" for conversion salinity was designed, value 6.29 J g–1 obtained. However, low specific surface area V2O5 inevitably resulted in limited active sites slow transport rates, inherent lower conductivity narrower layer spacing poor electrode kinetic performance cycle stability, hindering its practical application. To solve above problems, present work provides strategy using polyaniline (PANI) molecule chain intercalation to regulate V2O5, through expansion traction spacing, composite PANI/V2O5 (PVO) high prepared used as anode material electrochemical The significantly increased crystal plane (001) corresponding confirmed PANI by hydrogen bonding van der Waals force. more realize fast Na+ migration rate capacitance. Meanwhile, inserted chain, acts not only pillar enlarging diffusion channel but anchor locking gap bilayers, improves structural stability during process. proposed insertion conductive polymer has created new way improve device.
