Nanostructured flexible Mg-modified LiMnPO4 matrix as high-rate cathode materials for Li-ion batteries

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 ...

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...

High-performance spinel-rich Li1.5MnTiO4+δ ultralong nanofibers as cathode materials for Li-ion batteries

Recently, composite materials based on Li-Mn-Ti-O system were developed to target low cost and environmentally benign cathodes for Li-ion batteries. The spinel-layered Li1.5MnTiO4+δ bulk particles showed excellent cycle stability but poor rate performance. To address this drawback, ultralong nanofibers of a Li1.5MnTiO4+δ spinel-layered heterostructure were synthesized by electrospinning. Unifor...
