“…However, the presence of the binder decreases the overall electronic conductivity, but increases the electrochemical polarization in the anode. As reported in the literature (Kumar et al, 2019;Pan et al, 2019), polymetric conductive binders with strong mechanical binding force and even self-healing capability have been demonstrated to address detrimental volume effects of oxide/metal-based anode materials. Moreover, such polymetric binders play an additional role in offering the desired pathway for the charge transfer, resulting in free conductive carbon additives in the anode.…”

Metal oxides have been attractive as high-capacity anode materials for lithium-ion batteries. However, oxide anodes encounter drastic volumetric changes during lithium ion storage through the conversion reaction and alloying/dealloying processes, leading to rapid capacity decay and poor cycling stability. Here, we report a free-standing SnO 2 @reduced graphene oxide (SnO 2 @rGO) composite anode, in which SnO 2 nanoparticles are tightly wrapped within wrinkled rGO sheets. The SnO 2 @rGO sheet is assembled in high porosity via an anti-solvent-assisted precipitation of dispersed SnO 2 nanoparticles and graphene oxide sheets in the distilled water, followed by the filtration and post-annealing processes. Significantly enhanced lithium storage performance has been obtained of the SnO 2 @rGO anode compared with the bare SnO 2 anode material. A high charge capacity above 700 mAh g −1 can be achieved with a satisfying 95.6% retention after 50 cycles at a current density of 500 mA g −1 , superior to reserved 126 mAh g −1 and a much lower 16.8% retention of the bare SnO 2 anode. XRD pattern and HRTEM images of the cycled SnO 2 @rGO anode material verify the expected oxidation of Sn to SnO 2 at the fully-charged state in the 50th cycle. In addition, FESEM and TEM images reveal the well-preserved free-standing structure after cycling, which accounts for high reversible capacity and excellent cycling stability of such a SnO 2 @rGO anode. This work provides a promising SnO 2-based anode for high-capacity lithium-ion batteries, together with an effective fabrication adoptable to prepare different free-standing composite materials for device applications.

“…7,[21][22][23][24] Among these hybridizing with graphene based materials can give improved performance because of their large internal surface area for anchoring MOFs materials and excellent electrical conductivity for electron transport. [25][26][27][28][29][30][31] For example, Yaghi et al 18 showed as hybridizing MOFs with graphene has potential to enhance electrode materials for supercapacitor application. Zhou et al 32 reported Ni-MOFs@GO as pseudocapacitors materials with a capacitance of 1457.7 F g À1 at a current density of 1 A g À1 .…”

“…The diffraction peak of graphene (Gr) appeared at 26.69 • , corresponding to an interlayer spacing of 0.335 nm. The diffraction peak of GO film appeared at 10.26 • , corresponding to an interlayer spacing of 0.861 nm due to the attachment of oxygen-containing functional groups and residual solvents in the GO layers [35]. The diffraction peak of GO/VC-15% film appeared at 11.25 • , corresponding to an interlayer spacing of 0.785 nm, demonstrating that vitamin C partially reduced oxygen groups of GO partially.…”

The thermal dissipation issue of electronics devices becomes increasingly prominent as they evolve to smaller sizes and more complicated structures. Therefore, the development of materials with excellent heat conduction properties and light weight turns out to be an urgent demand to solve the heat transfer problem of electronics devices with high performance. For this purpose, we put forward an innovative strategy that carbonized dehydroascorbic acid (CDA) be applied to graphene layers for the targeted repair of defects among them and bridge connection of the layers to produce graphene heat conduction materials with excellent properties. Firstly, hydrogen bonds formed from dehydroascorbic acid (DHAA, products of the oxidation of vitamin C) and each of ketone, carboxyl, and oxhydryl groups on graphene layers were absorbed at targeted locations where oxidation graphene produces defects, then targeted repair was conducted for those defects to be filled and for the graphene layers of a small size to grow into large sheet materials with improved continuity by CDA generated in thermally pressing reduction reaction at 800 °C. In our investigation, the planar thermal conductivity of rGO/VC membrane reached 1031.9 ± 10.2 Wm−1K−1, while the added mass content of vitamin C (VC) was 15%. Being a reference, the planar thermal conductivity of primitive graphene membrane was only 610.7 ± 11.7 Wm−1K−1.
