Li3V2(PO4)3/Li3PO4 Cathode Materials for Li-Ion Batteries: Synthesis and Characterization

New materials for Li-ion batteries: synthesis and spectroscopic characterization of Li2(FeMnCo)SiO4 cathode materials

Improving cathode materials is mandatory for next-generation Li-ion batteries. Exploring polyanion compounds with high theoretical capacity such as the lithium metal orthosilicates, Li2MSiO4 is of great importance. In particular, mixed silicates represent an advancement with practical applications. Here we present results on a rapid solid state synthesis of mixed Li2(FeMnCo)SiO4 samples in a wi...

Comparative Issues of Cathode Materials for Li-Ion Batteries

After an introduction to lithium insertion compounds and the principles of Li-ion cells, we present a comparative study of the physical and electrochemical properties of positive electrodes used in lithium-ion batteries (LIBs). Electrode materials include three different classes of lattices according to the dimensionality of the Li ion motion in them: olivine, layered transition-metal oxides an...

Manganese-based cathode materials for Li-ion batteries

Controllable synthesis, morphology evolution and electrochemical properties of LiFePO4 cathode materials for Li-ion batteries.

Monodispersed LiFePO4 nanocrystals with diverse morphologies were successfully synthesized via a mild and controllable solvothermal approach with a mixture of ethylene glycol and oleic acid as the solvent. Morphology evolution of LiFePO4 nanoparticles from nanoplates to nanorods can be simply realized by varying the volume ratio of oleic acid to ethylene glycol. Moreover, the mechanism of compe...

Facile synthesis of nanostructured vanadium oxide as cathode materials for efficient Li-ion batteries

Homogeneous VO2 (B) nanorods approximately 100 nm in width and 1–2 mm in length have been fabricated via the hydrothermal process, and are then transformed into irregularly shaped V2O5 nanoparticles of several hundreds nanometers large and 20–30 nm thick after annealing the precursor material at 500 C for 30 min. Both the V2O5 sheet-like nanoparticles and VO2 (B) nanorods were tested as active ...
