Sucrose-assisted rapid synthesis of multifunctional CrVO4 nanoparticles: a new high-performance cathode material for lithium ion batteries

Abstract

The search of new multifunctional cathode materials, with new crystal structures and compositions, for lithium ion battery is extremely important to mitigate the drawbacks associated with the current electrode materials used in rechargeable lithium ion batteries. In this paper, orthovanadate family CrVO 4 has been identified and investigated as a new cathode material for high-rate and high-capacity lithium ion battery for the first time. A solution-based effective and versatile synthetic protocol has been proposed to synthesize CrVO 4 nanoparticles. Physical characterizations reveal that the prepared CrVO 4 consists of uniform and discreet nanoparticles of crystallite size~19 nm with widespread pore diameter, enhanced conductivity and surface area. The prepared CrVO 4 nanoparticles have been evaluated as a potential cathode material for lithium ion batteries, wherein the experimental results demonstrate enhanced lithium storage with high rate-capability and cyclability. The experimental results reveal that the proposed CrVO 4 is working through a partial conversion reaction mechanism.

Detection of NH3 gas using CrVO4 nanoparticles

“…They have shown that CrVO 4 -I activity for selective oxidation requires optimisation of the calcination temperature and that the bridging oxygen in V-O-Cr bonds is the structural moiety responsible for the catalytic activity favouring thus the monoclinic phase over orthorhombic phase of CrVO 4 for such purpose. Using external standard LaB 6 and Halder-Wagner method, the average size of coherently diffracting domains is (42.1 ± 0.5) nm suggesting preparation of ca two times larger crystalline nanodomains than in synthesis published by other authors who used sucrose carbonization supported preparation technique [36].…”

“…Such morphology can potentially aid the gas sensing ability because of the increased surface area. Such structure may also affect the electrical conduction mechanism, as shown by Shreenivasa et al [36].…”

“…Similarly, there has recently been renewed interest in AVO 4 structures for applications in oxygen evolution reaction, super protonic conductors, high-performance cathode material and photocatalytic research [34][35][36][37]. These oxides have been the subject of several studies due to their unique properties, such as ionic conductivity [38].…”

Synthesis, Characterization and Oer Performance of CrVO4 nanoparticles

“…Chromium vanadate nanoparticles were synthesized using our previous literature [16]. Briefly, stoichiometric amount of ammonium metavanadate was added into 20 mL of distilled water and later heated at 80 C.…”
