Single-crystalline (NH 4 ) 2 V 3 O 8 nanoflakes were successfully synthesized by a facile hydrothermal method. We investigated their electrochemical performance for use in lithium ion batteries for the first time. Interestingly, the as-prepared (NH 4 ) 2 V 3 O 8 electrode demonstrated good lithium storage properties. This material exhibited a high initial discharge capacity of 261.4 mAh g -1 at a current density of 150 mA g -1 . Apart from the capacity loss in the first two cycles, the discharge capacity remained relatively stable and a capacity of 215.8 mAh g -1 was maintained after 30 cycles, indicating good cycling stability. The Coulombic efficiency was close to 100 % during the cycling, revealing that the intercalation/deintercalation of Li ions in this material was highly reversible. The good electrochemical performance of (NH 4 ) 2 V 3 O 8 was mainly attributed to its flake-like morphology and intrinsically stable layered structure.

“…Monoclinic VO 2 (M) phase transforms into tetragonal rutile VO 2 (R) at about 68 C [22][23][24][25]. The electrochemical properties of metastable VO 2 (B) with various morphologies, such as nanorods, nanowires, nanoribbons, nanobelts, nanoflowers, and nanostructures, and their performances as electrode materials in LIBs have been widely studied [13,[26][27][28][29][30][31][32][33]. However, to the best of our knowledge, the electrochemical properties of the most stable tetragonal rutile VO 2 (R) have not been investigated.…”

“…VO 2 (B)/C has been synthesized by Zhao et al [234] via a facile surfactant-free hydrothermal method using V 2 O 5 and sucrose as reactants. Sucrose acts as reductant and carbon source, and when the carbon content is 0.96 wt%, the VO 2 (B)/C shows a good electrochemical performance with initial discharge capacity of 218.6 mAh g −1 at a current density of 50 mA g −1 in the voltage range of 1.5-4.0 V. After 100 cycles, the discharge capacity remains 152.6 mAh g −1 .…”

Lithium ion batteries (LIBs) represent one of the most promising solutions for environmentally friendly transportation such as electric vehicles. The demand for high energy density, low cost and environmentally friendly batteries makes high-capacity cathode materials very attractive for future LIBs. Layered LiNi x Co y Mn z O 2 (x+y+z=1), Li-rich oxides and Li-V-O compounds have attracted much attention due to their high capacities in recent years. In this review, we focus on the state-of-the-art research activities related to LiNi x Co y Mn z O 2 , Li-rich oxides and Li-V-O compounds, including their structures, reaction mechanisms during cycling, challenges and strategies that have been studied to improve their electrochemical performances. layered LiNi x Co y Mn z O 2 , Li-rich layered oxide, Li-V-O compound, cathode material, Li-ion battery Citation: Zhang Y D, Li Y, Xia X H, et al.
