Abstract Transition metal oxides as anode materials have received extensive research owing to the high specific capacity. Whereas, the rapid decline of battery capacity caused by volume expansion and low electrical conductivity hinders the practical application of transition metal oxides. This study reported a pseudo-capacitance material polypyrrole coated Fe2O3/Mn2O3 composites material as a high stability anode for lithium-ion batteries. The polypyrrole coating layer can not only serve as a conductive network to improve electrode conductivity but also can be used as a protective buffer layer to suppress the volume change of Fe2O3/Mn2O3 during the charging and discharging process. At the same time, the porous structure of Fe2O3/Mn2O3 composite can not only provide more active sites for lithium storage but also play a certain buffer effect on the volume change of the material. Polypyrrole-coated Fe2O3/Mn2O3 composite as the anode for lithium-ion batteries shows great electrochemical storage performance, with high specific capacity (627 mAh g− 1 at a current density of 1A g− 1), great cycle stability (the capacity not shows obvious signs of attenuation after 500 cycles) and rate performance (432 mAh g− 1 at a current density of 2.0 A g− 1).

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.
