Amorphous molybdenum oxide films with almost 20[Formula: see text][Formula: see text]m thickness are electrodeposited on the Cu foils from a citrate-ammonia molybdate bath containing Ni[Formula: see text] ions. The content of Ni in the oxide films is very low, 0.87 at.%. XRD and FTIR data suggest that they are composed of hydrous MoO2. The multilayer and cracked structures are characterized by scanning electron microscopy (SEM), and are beneficial to transmission of Li[Formula: see text] ions between the electrolyte and anode materials. Galvanostatic battery testing shows that amorphous molybdenum (IV) oxides as anodes for lithium-ion batteries exhibit a high specific capacity of 876[Formula: see text]mA[Formula: see text]h[Formula: see text]g[Formula: see text] at a current density of 50[Formula: see text]mA[Formula: see text]g[Formula: see text], good capacity retention as high as 97.4% after 20 cycles.

Silicon, an anode material for lithium ion batteries, has the highest theoretical specific capacity ([Formula: see text] mAh/g). The actual lithium storage capacity of [Formula: see text] mAh/g is about 10 times that of the graphite anode materials class. This study involves magnesium heat reduction of the SiO2 preparation of silicon carbon composites. The Si/SiC composite shows a high initial specific capacity of 1406.7 mAh/g with a current density of 0.1 A/g. The morphology and pore size inherited from the SiO2 aerogel counteracts the volume expansion during the lithiation/delithiation process. This paper provides an articulate methodology for designing silicon anode material for high-performance rechargeable lithium-ion batteries.

Nanoscale Fe3O4-Sn@CNFs was prepared by loading Fe3O4 and Sn nanoparticles onto CNFs synthesized via electrostatic spinning and subsequent thermal treatment by solvothermal reaction, and were used as anode materials for lithium-ion batteries. The prepared anode delivers an excellent reversible specific capacity of 1120 mAh·g−1 at a current density of 100 mA·g−1 at the 50th cycle. The recovery rate of the specific capacity (99%) proves the better cycle stability. Fe3O4 nanoparticles are uniformly dispersed on the surface of nanofibers with high density, effectively increasing the electrochemical reaction sites, and improving the electrochemical performance of the active material. The rate and cycling performance of the fabricated electrodes were significantly improved because of Sn and Fe3O4 loading on CNFs with high electrical conductivity and elasticity.
