Transition metal oxide is one of the most promising anode materials for lithium-ion batteries. Generally, the electrochemical property of transition metal oxides can be improved by optimizing their element components and controlling their nano-architecture. Herein, we designed nonstoichiometric Cu0.6Ni0.4Co2O4 nanowires for high performance lithium-ion storage. It is found that the specific capacity of Cu0.6Ni0.4Co2O4 nanowires remain 880 mAh g−1 after 50 cycles, exhibiting much better electrochemical performance than CuCo2O4 and NiCo2O4. After experiencing a large current charge and discharge state, the discharge capacity of Cu0.6Ni0.4Co2O4 nanowires recovers to 780 mAh g−1 at 50 mA g−1, which is ca. 88% of the initial capacity. The high electrochemical performance of Cu0.6Ni0.4Co2O4 nanowires is related to their better electronic conductivity and synergistic effect of metals. This work may provide a new strategy for the design of multicomponent transition metal oxides as anode materials for lithium-ion batteries.

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).

Phosphorization of metal oxides/hydoxides to promote electronic conductivity as a promising strategy has attracted enormous attention for improving the electrochemical properties of anode material in lithium ion batteries. For this article, selective phosphorization from NiCo2O4 to NiO/Ni2Co4P3 microspheres was realized as an efficient route to enhance the electrochemical lithium storage properties of bimetal Ni-Co based anode materials. The results show that varying phosphorizaed reagent amount can significantly affect the transformation of crystalline structure from NiCo2O4 to intermediate NiO, hybrid NiO/Ni2Co4P3, and, finally, to Ni2Co4P3, during which alterated sphere morphology, shifted surface valance, and enhanced lithium-ion storage behavior are detected. The optimized phosphorization with 1:3 reagent mass ratio can maintain the spherical architecture, hold hybrid crystal structure, and improve the reversibly electrochemical lithium-ion storage properties. A specific capacity of 415 mAh g−1 is achieved at 100 mA g−1 specific current and maintains at 106 mAh g−1 when the specific current increases to 5000 mA g−1. Even after 200 cycles at 500 mA g−1, the optimized electrode still delivers 224 mAh g−1 of specific capacity, exhibiting desirable cycling stability. We believe that understanding of such selective phosphorization can further evoke a particular research enthusiasm for anode materials in lithium ion battery with high performances.
