AB  - Electrochemical and structural properties of LiV2O5 cathode were investigated. Obtained by solid state reaction at high temperature the material crystallized as gamma polymorph phase, γ-LiV2O5. The gamma structure provides two crystallographic sites to accommodate lithium ions, Li1 and Li2 position. Lithium insertion at these two sites occurs at two respective voltages versus lithium metal: ~3.6 V (Li1) and ~2.4 V (Li2). Intercalation at Li1 position is reversible in both organic and aqueous electrolyte and provides stable cycling performance at the high voltage. On the contrary, sluggish insertion/removal of Li+ at Li2 sites causes unstable performance and significant storage capacity fade at lower voltages. Lithium diffusion 3d landscape was determined by bond valence calculations applied on the γ-LiV2O5 phase, as well as on the metastable phases of γ′-V2O5 and ζ-Li2V2O5 that exist at high and low voltages respectively. The model was proposed based on inactivity of Li2 position of the metastable ζ-Li2V2O5 phase which provides explanation for the observed storage capacity loss at low voltages.

AB  - Lithium-ion batteries are under intense scrutiny as alternative energy/power sources. Their electrochemistry is based on intercalation/deintercalation reactions of lithium ions within a crystal structure of an electrode material. Therefore, the structure itself determines both the electrode operating voltage and the transport pathways for lithium ions. Some oxide- and polyanion-based materials are synthesized by using ultrasonic spray pyrolysis method. The crystal structure refinement was based on the Rietveld full profile method. All relevant structural and microstructural crystal parameters that could be significant for electrochemical intercalation/deintercalation processes were determined. It was also shown that the structural and microstructural properties are significantly dependent on the synthesis condition. Electrochemical performances as cathode materials for lithium-ion batteries were examined through galvanostatic charge/discharge cycling. Galvanostatic cycling revealed variation in discharge curve profiles. It comes from different mechanism of lithium intercalation and also from the degree of structural order. Structural analyses revealed difference in the dimensionality of lithium-ion motion.

AB  - The electrochemical insertion of lithium ions in V2O5 produces various crystal structures depending on lithium concentration. Compositions with lithium content in the range of 1 ≤ x ≤ 1.8 take orthorhombic γ-LixV2O5 form. γ-LixV2O5 is capable to accommodate more than one lithium ion per formula unit and therefore interesting to be used as a cathode of lithium-ion battery. Here are
presented electrochemical performances of γ-LiV2O5 obtained through solid-state reaction. Before galvanostatic cycling the as-synthesized powder is characterized by X-ray powder diffraction, field emission scanning electron microscopy, and FTIR spectroscopy. The crystal structure of the powder is refined in the orthorhombic Pbnm space group. During galvanostatic cycling in a large potential window capacity decrease is observed. In order to reveal the origin of capacity decay the bond valence analysis was performed. It provided a model of lithium diffusion network for the γ-LixV2O5 phase, as well as for the end members obtained at low and high voltages.

AB  - Lithium iron phosphate is a promising cathode material for lithium ion battery application thanks to its good characteristics. Here is presented the freeze drying method for the preparation of carbon coated LiFePO4, where PVP is used as a carbon source. The main advantage of this method is mixing at the atomic level and introducing the carbon source into the precursor solution. The synthesis process can be divided into three stages: freezing of a precursor solution, drying under vacuum until water evaporates and calicination of as-dried powder at slightly reductive atmosphere. Powder X-ray diffraction measurement demonstrated single phase LiFePO4 with crystallite size of 45.8 nm. Morphology and particle size was revealed with scanning electron microscopy and particle size analyzer. Galvanostatic cycling from 2.3 to 4.1 V vs. Li/Li+, shows typical LiFePO4 redox behavior with plateau at 3.4 V. The discharge capacity value obtained at C/10 rate was 154 mAh- 1, with decrease on greater C-rates.
