V2O5 xerogel electrodes with much enhanced lithium-ion intercalation properties with N2 annealing
V2O5 xerogel films were fabricated by casting V2O5 sols onto FTO glass substrates and annealing at 300 C for 3 hours in nitrogen and air. The films annealed in nitrogen and air possessed different grain size and crystallinity. Optical absorption measurements and electrochemical impedance analyses revealed a reduced optical bandgap and enhanced electrical conductivity of N2 annealed V2O5 film. L...

متن کاملAtomic layer deposition of Al2O3 on V2O5 xerogel film for enhanced lithium-ion intercalation stability
V2O5 xerogel films were fabricated by casting V2O5 sols onto fluorine-doped tin oxide glass substrates at room temperature. Five, ten and twenty atomic layers of Al2O3 were grown onto as-fabricated films respectively. The bare film and Al2O3-deposited films all exhibited hydrous V2O5 phase only. Electrochemical impedance spectroscopy study revealed increased surface charge-transfer resistance o...
متن کاملNanostructured Vanadium Oxide Electrodes for Enhanced Lithium-Ion Intercalation
Intercalation-electrode materials are electroactive and serve as host solids into which guest species are reversibly intercalated from an electrolyte. Currently there are three intercalation materials that are used commercially as positive-electrode materials in lithium-ion rechargeable batteries: LiCoO2, LiNiO2, and LiMn2O4. LiCoO2 is the most popular among the possible cathode materials becau...
متن کاملAdditive-free synthesis of unique TiO2 mesocrystals with enhanced lithium-ion intercalation properties†
Unique nanorod-like mesocrystals constructed from ultrathin rutile TiO2 nanowires were successfully fabricated for the first time using a low-temperature additive-free synthetic route, and the mesocrystal formation requirements and mechanism in the absence of polymer additives were discussed. The ultrathin nanowires were highly crystalline and their diameters were found to be ca. 3–5 nm. The ru...
