“…Unfortunately, none of these enabled satisfactory long term stability (maximum 100 cycles), and most of them showed a high 1 st cycle irreversible capacity (see Table 2 ). At the same time, previously reported graphene-containing alloy (e.g., Sn, [ 144 ] SnO 2 [145][146][147][148][149] or Si [150][151][152][153] ), conversion (e.g., Fe 3 O 4 , [154][155][156][157] Co 3 O 4 [158][159][160][161] or CuO [162][163][164] ) and insertion (e.g., TiO 2 [165][166][167][168] or LTO [169][170][171] ) hybrids were further improved. Interestingly, some appealing approaches, such as the use of ternary hybrids (e.g., RGO/SnO 2 /Fe 3 O 4 [ 172 ] or RGO/CNT/ Sn [ 173 ] ), porous 3D (e.g., RGO/Fe 3 O 4 [ 174,175 ] ) and hollow architectures (e.g., RGO/Fe 3 O 4 [ 176 ] and RGO/TiO 2 [ 168 ] ), were introduced.…”

“…[26,39] These comparisons imply that the SnO 2 -SiC/G core-shell structure with a few-layer graphene coating can effectively accommodate the mechanical stress experienced and maintain good electrical contact among electroactive particles to further improve upon the previously reported electrochemical reversibility for the alloying reaction. [11,12,14,26,27,[37][38][39][40][41][42][43][44] To further study the effect on the Li-storage properties of the as-prepared SnO 2 -SiC/G core-shell structure, including the alloying and conversion reactions, a series of electrochemical measurements were performed at the wider voltage window of 3.0 to 0.01 V. Figure 4a shows typical cyclic voltammetry . Interestingly, there is almost no noticeable change of current or potential observed for the three pairs of redox peaks in the subsequent cycling compared to that of pure SnO 2 electrodes (see Supporting Information, Figure S1), indicating that the conversion reaction of the SnO 2 -SiC/G coreshell structures seems to be as reversible as the alloying and dealloying reactions.…”

“…[14,26,27] A SnO 2 -graphene nanocomposite with 40 wt% SnO 2 prepared by in situ chemical synthesis still maintained a reversible capacity of 520 mA h g −1 after 100 cycles at a low mass normalized current of 0.01 A g −1 between 0.02 and 1.5V. [14] Zhang et al reported monodispersed SnO 2 nanoparticles on both sides of single-layer graphene sheets, which exhibited a high reversible capacity of 786 mAh g −1 and 71% retention of its initial capacity in the voltage range of 0.02 to 3 V (vs. Li/Li + ) after 50 cycles.…”

“…Graphene has a two-dimensional structure of carbon with a carbon{carbon bond length of 0.142 nm. The combination of large thermal conductivity, unique electrical properties, and large surface area [2] makes toxic gases. Among metal oxides, SnO 2 is well known for the detection of di erent pollutants.…”
