SnO2-reduced graphene oxide nanoribbons as anodes for lithium ion batteries with enhanced cycling stability

Three dimensional Graphene aerogels as binder-less, freestanding, elastic and high-performance electrodes for lithium-ion batteries

“…Moreover, the lithium ions could be adsorbed to the surface of graphene layers physically during the charging and discharging cycles because of the extensive surface area. The synergistic effect344344 between SnO 2 nanoparticles and graphene layers as well as the decomposition of electrolyte could contribute to the increase in capacity4546. Another reason for the superior performance of the electrode was the presence of SnO 2 nanoparticles, and the electrical conductivity, and mechanical flexibility of the graphene structure.…”

“…Electrochemical impedance spectroscopy (EIS) measurements were utilized to study the electrode’s superior electrochemical performance and the kinetics properties46. Figure 5 shows the Nyquist plots of the SnO 2 -rGA after 10 cycles and SnO 2 -rGA after 200 cycles as well as the equivalent circuit model.…”

“…It was found that R 2 and R 3 were due to the solid electrolyte interface impedance and to the charge transfer resistance, respectively. Moreover, the liner part of the plot is likely due to the lithium diffusion in the 3D porous network4651. The semicircle diameter of the SnO 2 -rGA-20 was smaller than that of SnO 2 -rGA-10, implying that the prepared electrodes were stable during charge/discharge cycles52.…”

Preparation of re-constructed carbon nanosheet powders and their efficient lithium-ion storage mechanism

“…To date, although several anode materials such as SnO2 [5], TiO2 [6], Si [7], P [8], and MoSx [9], have been investigated as alternative candidates for anode materials to increase the specific capacity, various carbon materials remain the hot candidates because of their intrinsic properties [10]. In particular, compared with the low theoretical capacity of graphitic carbon, carbon nanomaterials and their composites exhibit higher capacity and potential application.…”

Cu particles decorated pomegranate-structured SnO2@C composites as anode for lithium ion batteries with enhanced performance

“…For instance, the preparation of nanostructured SnO 2 -based materials [6][7][8][9][10][11][12], such as spheres, nanowires, nanotubes, nanoflakes and nanoplatelets has been investigated for shortening Li + diffusion length and accommodating large mechanical strain associated with structure and volume changes. Researchers also focused on using varied carbonaceous materials including carbon nanotubes, carbon layer and graphene as buffer carriers for suppressing the pulverization and capacity fading of SnO 2 -based anodes [13][14][15][16].…”
