Abstract

α-MoO3–In2O3 core–shell nanorods have been synthesized by a hydrothermal method. As anodes of LIBs, they exhibit excellent lithium storage performance with high reversible capacity, excellent cyclability and good rate capability.

“…[43] They also designed a-MoO 3 @MnO 2 core-shell nanorods with ac apacity of 1475 mA hg À1 at 0.1 C. [44] The capacity can be kept at 1127 mA hg À1 after 50 cycles, whichissuperior to that of the bare MoO 3 and pristine MnO 2 electrodes. By combining the physical and electrochemical properties of variousm aterials and making use of their respective merits to offset the imperfection of others, many hybrid MoO 3 -based electrodes have been fabricated with improved electrochemical properties.…”

[43] They also designed a-MoO 3 @MnO 2 core-shell nanorods with ac apacity of 1475 mA hg À1 at 0.1 C. [44] The capacity can be kept at 1127 mA hg À1 after 50 cycles, whichissuperior to that of the bare MoO 3 and pristine MnO 2 electrodes. Such excellent electrochemical properties can be ascribed to the synergistic effect of the short lithium-ion diffusion pathway and interfacial spaces between the core and shell components.…”

A New Way to Prepare MoO3/C as Anode of Lithium ion Battery for Enhancing the Electrochemical Performance at Room Temperature

“…In addition, it has been confirmed that the electrochemical performance is strongly related to the electrical conductivity of the electrodes. In this regard, different conductive materials, such as conductive polymer [17], graphene [18][19][20], amorphous carbon [21][22][23], carbon nanotubes [24] and In 2 O 3 [8] have been used for incorporating MoO 3 within the electrode base material.…”

“…Sn [2], Si [3] and Ge [4]), and conversion-type (e.g. Co 3 O 4 [5], V 2 O 5 [6], Fe 2 O 3 [7] and MoO 3 [8]). Although graphite has been extensively employed as anode material in commercial LIBs for many years, its relatively low Li ion storage capacity (theoretical capacity of 372 mAh/g) restricts the further improvement of LIBs.…”
