Structural changes of Nb2O5 and V2O5 as rechargeable cathodes for lithium battery

XPS study of Li ion intercalation in V2O5 thin films prepared by thermal oxidation of vanadium metal

“…The structural changes of V 2 O 5 were widely studied for the first time by Murphy et al [4] and Cocciantelli et al [5]. V 2 O 5 thin films have recently emerged as interesting materials for rechargeable microbatteries due to their high specific energy densities and capacities [6][7][8][9][10]. Many investigations have focused on the electrochemical properties of vanadium oxide prepared by different methods such as chemical [11,12] or physical [13][14][15][16] vapour deposition techniques and wet chemical/electrochemical [17][18][19] deposition methods on a variety of substrates, like glass, silicon, titanium or stainless steel.…”

Thin films of vanadium oxide grown on vanadium metal: oxidation conditions to produce V2O5 films for Li-intercalation applications and characterisation by XPS, AFM, RBS/NRA

“…The beam current was set to 150 nA. Areal densities of oxygen were determined by NRA via the 16 In order to study the intercalation properties of the oxide films, chronopotential curves of the Li-intercalation were taken at potentials between 1.5 and 4.0 V versus Li/Li C , with a total current set to 2 µA, using a two electrode 'coin' cell made of stainless steel. Cyclic voltammograms were also recorded in a conventional three-electrode glass cell.…”

Synthesis of mesoporous Nb2O5 with crystalline walls and investigation of their photocatalytic activity

“…The T-phase has attracted interest due to its high electrochemical stability and an excellent cycling behavior. 37) Furthermore, we investigated the photocatalytic activity by using several types of mesoporous Nb 2 O 5 prepared with P123. Although all the mesoporous Nb 2 O 5 samples show photocatalytic activity over their composition reaction with methylene blue (MB) molecules, their reaction rate depends on the crystalline framework with a large surface area.…”
