Validating the Electronic Structure of Vanadium Phosphate Cathode Materials

“…NASICON-type Na 3 V 2 (PO 4 ) 3 (NVP) and anti-NASICON Li 3 V 2 (PO 4 ) 3 (LVP) are promising cathode materials for both sodium- and lithium-ion battery applications, respectively. , Each material possesses a distinct crystal and electronic structure that allows for high stability, energy storage capacity, and fast ionic conduction through an interconnected framework of edge- and corner-shared PO 4 tetrahedra and VO 6 octahedra ( D Li, LVP = ∼10 –9 to ∼10 –10 cm 2 s –1 and D Na,NVP = ∼10 –11 cm 2 s –1 ). ,− Recent studies aimed specifically at high-rate Li-ion storage have focused on the practical use of monoclinic LVP, which shows a high-voltage operating cutoff at 4.8 V vs Li +/0 (compared to the standard 4.3 V for LVP (two-electron transfer)). ,, In the study by Ni et al, this 4.8 V cutoff enabled LVP to achieve a higher rate capability, reversible three Li + intercalation at up to 100C (1C = 133 mAh g –1 , theoretical capacity for a two-electron transfer in LVP) with specific capacity maintained at 119 mAh g –1 . These outcomes rival commercial LiFePO 4 performance …”

Synthesis, characterisation, and feasibility studies on the use of vanadium tellurate(vi) as a cathode material for aqueous rechargeable Zn-ion batteries

“…35 This may be reduced by optimising the electrolyte solution, tailoring the crystal size, morphology, and carbon coating of the material, among others. 36,37 Zn 2p XPS spectrum of the electrode aer 6 h under rest conditions (OCV) conrmed the presence of Zn 2+ ions by showing two asymmetric peaks with binding energies of 1021.5 and 1044.6 eV, assigned to Zn 2p 3/2 and Zn 2p 1/2 core levels, respectively (Fig. 3a).…”

Review—Nanomaterials Green Synthesis for High-Performance Secondary Rechargeable Batteries: Approaches, Challenges, and Perspectives

“…The [XO 4 ] n− anion groups stabilize the crystal structure of the material in the structure of polyanion materials, and the O 2are connected in these groups, which provides excellent structural and thermal durability. 174 Li 3 V 2 (PO 4 ) 3 (LVP), as well-known cathode material with a monoclinic structure, has high working voltage, high specific capacity, and long cycle life, but its poor electronic conductivity restricted its practical applications. 175 Thereby, Chen group 176 attempted to enhance the electronic conductivity of LVP by designing lotus root-like Li 3 V 2 (PO 4 ) 3 /C composite cathode active materials by a frequent immersion operation using the dandelion as a bio-template.…”
