Carbothermal synthesis, spectral and magnetic characterization and Li-cyclability of the Mo-cluster compounds, LiYMo3O8 and Mn2Mo3O8

Anodic electrochemical performances of MgCo 2 O 4 synthesized by oxalate decomposition method and electrospinning technique for Li-ion battery application

“…The gradual increase in reversible capacities during cycling may result from the formation of a polymeric surface layer on the active material and other reasons like more active participation during electrochemical cycling. The polymer layer builds-up on the surface and within the pores of the porous active material, and thus increases the Li-storage, similar trend was noted in other anode materials [4,[39][40][41][42].

Preparation, temperature dependent structural, molecular dynamics simulations studies and electrochemical properties of LiFePO4

“…Various methods employed for optimizing morphology, structure and electrochemical performance of this compound are summarized in a recent review [3]. Among these the carbothermal reduction method is one of the simple, versatile and cost-effective large scale preparative methods [12][13][14][15].…”

Sputtered lithium nickel vanadium oxide (LiNiVO4) films: Chemical compositions, structural variations, target history, and anodic/cathodic electrochemical properties

“…However same material cycled in the range of 0.02-3.0 V, the XRD pattern at end of discharge (0.02 V) (anodic) or cycled electrode in charged cycle state (3.0 V), the original crystal structure was completely destroyed regardless of whether the LiNiVO 4 material in nano/polycrystalline thin film or bulk form [48,46]. Our experience, in most of the anodic metal oxide either in thin film [12] or bulk material form [68], structure destruction was occurred during first discharge, except in case of LiYMo 3 O 8 cluster compound [13]. We note from the application point of view, amorphous LiNiVO 4 films (or other metal oxide thin films) are interesting because any further heating is unnecessary, thus we can fabricate thin films onto plastic conducting or metallic substrates and these films deliver higher capacity compared to graphite electrodes and it has a lower operating voltage (based on our experimental studies sintered films slightly better performance and stability due nanocrystalline nature of the films).…”

“…Sn, In, Sb [9,10], Si/C [11], (ii) conversion reaction ex. NiO [12], LiYMo 3 O 8 , Mn 2 Mo 3 O 8 [13] and Fe 2 O 3 [14], Fe 3 O 4 [15], and (iii) metal oxides under goes both alloying-de-alloying and conversion reactions for ex. VSbO 4 [16].…”
