Electrochemical performances of carbon coated FeSbO 4 as anode material for lithium batteries

Mn2Sb2O7/Reduced Graphene Oxide Composites with High Capacity and Excellent Cyclic Stability as Anode Materials for Lithium‐Ion Batteries

“…[6][7][8][9][10] By virtue of its high specific capacity (theoretically 1109 mAh g À 1 ), Sb 2 O 3 has been investigated as a promising anode for LIBs based on conversion and alloying reactions. [15][16][17] Because the transition metal M can react with Li 2 O to improve electrochemical performances and to accommodate volume changes of the Li x Sb active during the delithiation/lithiation processes. To solve these problems, various methods have been proposed and studied, including preparation of nanomaterials, core-shell structures and ternary compounds, etc.…”

“…[11,12] However, the rapid capacity fading and poor reversibility of Sb 2 O 3 are observed initially because of large volume changes upon cycling. [17] And the reaction product Li 2 O can act as a "self-host" to alleviate the volume expansion/ contraction pressure. [13][14][15][16] In these methods, ternary compounds MSb x O y (M=Fe, V, Co, Ni, etc.…”

“…; x = 1, 2, 3; y = 1, 2, 3) have received extensive attention. Zeng et al [17] synthesized FeSbO 4 with discharge capacities of 112.6 and 76.3 mAh g À 1 after 200 cycles at 50 and 200 mA g À 1 , respectively. [17] And the reaction product Li 2 O can act as a "self-host" to alleviate the volume expansion/ contraction pressure.…”

[18] In recent years, Han et al [15] prepared NiSb 2 O 6 by a solidstate reaction, and the results showed that its discharge capacity was only 273.5 mAh g À 1 at 50 mA g À 1 after 100 cycles.…”
