The advancements in wearable electronic devices make it urgent to develop highperformance flexible lithium-ion batteries (LIBs) with excellent mechanical and electrochemical properties. Herein, we design a new 3D hierarchical hybrid sandwich flexible structure by anchoring SnO 2 nanosheets (SnO 2-NSs) on flexible carbon cloth and coating with thin amorphous carbon (AC) layer (CF@SnO 2-NS@AC). The carbon cloth substrate works as the backbone and the current collector, while the thin AC layer provides extra support during the electrode expansion. The new architecture can be utilised as a binder-free electrode and presents extraordinary mechanical flexibility and outstanding electrical stability under external stresses. The new electrode can deliver a specific capacity as high as 968.6 mAh g-1 after 100 cycles at 85 mA g-1 , which also shows remarkable rate capability and an excellent high current cycling stability. The outstanding electrochemical performance combined with the high mechanical flexibility and invariable electrical conductivity during/after different bending cycles make the new structure a promising oxide anode for flexible batteries. With the possibility of using a similar approach to design flexible cathode, the present work opens the door to empower the next-generation wearable devices and smart clothes with a robust and reliable battery.

“…We propose that the superior electronic conductivity of GNC‐8 mainly results from the reduced graphene oxides that like a conductive network. (2) The PANI‐derived porous carbon not only prevent the restacking and agglomeration of graphene nanosheets but also offer a moderate N content (≈2%) leading to the improvement of wettability that increase the accessibility of electrolyte ions to electrode materials . (3) The rational hierarchically micro/mesoporous structure contributes a lot in improving the capacitive performance.…”

High energy density, durability, and flexibility of supercapacitors are required urgently for the next generation of wearable and portable electronic devices. Herein, a novel strategy is introduced to boost the energy density of flexible soild-state supercapacitors via rational design of hierarchically graphene nanocomposite (GNC) electrode material and employing an ionic liquid gel polymer electrolyte. The hierarchical graphene nanocomposite consisting of graphene and polyaniline-derived carbon is synthesized as an electrode material via a scalable process. The meso/microporous graphene nanocomposites exhibit a high specific capacitance of 176 F g −1 at 0.5 A g −1 in the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIBF 4 ) with a wide voltage window of 3.5 V, good rate capability of 80.7% in the range of 0.5-10 A g −1 and excellent stability over 10 000 cycles, which is attributed to the superior conductivity (7246 S m −1 ), and quite large specific surface area (2416 m 2 g −1 ) as well as hierarchical meso/micropores distribution of the electrode materials. Furthermore, flexible solid-state supercapacitor devices based on the GNC electrodes and gel polymer electrolyte film are assembled, which offer high specific capacitance of 180 F g −1 at 1 A g −1 , large energy density of 75 Wh Kg −1 , and remarkable flexible performance under consecutive bending conditions.

“…Various attempts have been made to overcome these limitations. For example, various carbon-based SnO 2 composites have been developed to accommodate the volume expansions caused by cycling in order to achieve cycling stability [8][9][10][11][12][13][14][15][16][17][18]. However, this carbon composite approach cannot improve the ICE of SnO 2 anodes.…”

HIGHLIGHTS• SnO 2 -Co-carbon nanocomposites were in-situ prepared from Co-based metal-organic frameworks and showed a remarkably high initial Coulombic efficiency (82.2%) and a capacity of ~ 800 mAh g −1 at a high current density of 5 A g −1 .• Facile approach for designing highly reversible and stable electrodes for next-generation high-performance lithium-ion batteries.ABSTRACT The two major limitations in the application of SnO 2 for lithium-ion battery (LIB) anodes are the large volume variations of SnO 2 during repeated lithiation/delithiation processes and a large irreversible capacity loss during the first cycle, which can lead to a rapid capacity fade and unsatisfactory initial Coulombic efficiency (ICE). To overcome these limitations, we developed composites of ultrafine SnO 2 nanoparticles and in situ formed Co(CoSn) nanocrystals embedded in an N-doped carbon matrix using a Co-based metal-organic framework (ZIF-67). The formed Co additives and structural advantages of the carbon-confined SnO 2 /Co nanocomposite effectively inhibited Sn coarsening in the lithiated SnO 2 and mitigated its structural degradation while facilitating fast electronic transport and facile ionic diffusion. As a result, the electrodes demonstrated high ICE (82.2%), outstanding rate capability (~ 800 mAh g −1 at a high current density of 5 A g −1 ), and long-term cycling stability (~ 760 mAh g −1 after 400 cycles at a current density of 0.5 A g −1 ). This study will be helpful in developing high-performance Si (Sn)-based oxide, Sn/Sb-based sulfide, or selenide electrodes for LIBs. In addition, some metal organic frameworks similar to ZIF-67 can also be used as composite templates.
