over other rechargeable battery technologies, including relatively high energy and power densities, long cycling life, little memory effect, and low self-discharge. [6][7][8] When used in flexible electronics, LIBs need to be flexible, thin, stretchable, and even foldable. [9][10][11] So far, flexible LIBs have been investigated for decades. Numerous strategies, such as fiber-shaped, [12] sponge-like, [13] spring-like stretchable, [14] and paper-like LIBs [15] have been reported, but none has been successful in real commercial applications. The reasons may be due to 1) low energy density, 2) poor mechanical flexibility, 3) poor safety, and 4) not being suitable for scalable applications. Presently, the development in the field of flexible LIBs is still at the early stage of research in laboratories, and most of the reports focus on flexible electrodes based on flexible current collectors. [13,[15][16][17][18] Conventional metal foils (aluminum [Al] and copper [Cu]) as current collectors to support active materials [19] are unfit for flexible batteries because the active materials (cathode and anode) are easily delaminated from their smooth surface when the flexible batteries are bent. In addition, the high-density characteristics of metal restrict the mass energy density of LIBs. Therefore, replacing the metal foils with a highly conductive, light-weight, thin, and flexible current collector could enhance both the mass energy density and mechanical flexibility.Recently, carbon-based materials featuring good electrical conductivity, high mechanical durability and low density are considered as the promising choice for current collectors in flexible LIBs. [20,21] The reported carbon based materials include carbon nanotubes (CNTs), [15,[22][23][24][25][26] carbon cloth, [27] carbon fibers, [28] graphene based film, [29] and foam. [30,31] Thanks to the tremendous research efforts devoted over the past decades, research on flexible LIBs has made substantial progress. However, from the perspective of scalable applications, the above-mentioned carbon based materials still have some insurmountable problems. First, due to the difficult dispersion of CNTs and other nanocarbon materials in solution, the major challenge is to fabricate CNT films with uniform thickness and mass. [26] Although flexible CNT films can also be prepared directly through the floating-catalyst chemical vapor deposition (CVD) method at the high-temperature zone of the chamber with robustness and high conductivity, the area of the obtained films is limited by the diameter of the reaction chamber. [32,33] Second, for carbon cloth, there are numerous With the development of flexible electronics, flexible lithium ion batteries (LIBs) have received great attention. Previously, almost all reported flexible components had shortcomings related to poor mechanical flexibility, low energy density, and poor safety, which led to the failure of scalable applications. This study demonstrates a fully flexible lithium ion battery using LiCoO 2 as the cathode, Li 4 Ti ...

Poor cyclability and rate performance always impedet he development of transition metal phosphidebased anode materials. Many strategies have been used to addresst he above problems, such as the designing of hierarchicals tructures,c ombination with carbon materials, and doping with other metal elements. Considering thoses trategies, af lower-like Fe-doped CoP material is designed. The synthesis consists of microsheets grown on ac arbon membrane (CM, leaves as precursor) through ah ydrothermal methoda nd in situ phosphorization.T he Fe dopinga nd carbon membrane synergistically induce the formationo fa flower-like hierarchical microstructure duringt he crystalgrowingp rocess. The unique hierarchical microstructure in-creases thec ontact area between electrode and electrolyte, and accommodates the volume expansion duringc ycling. The hierarchicalF e-doped CoP grownd irectly on the carbon membrane increases the active sites for intercalation of sodiums pecies and furtherp romotes the internal electron conduction in the Fe-doped CoP/CM electrode. Thereby,t he Fe-doped CoP/CM as the anode electrode fors odium ion batteries exhibits ah igh specific capacityo f5 15 mA hg À1 at 100 mA g À1 after 100 cycles. Even if the current density rises to 500 mA g À1 ,t he specific capacity is stillm aintained at 324 mA hg À1 after 500 cycles, showings uperior rate performances and cyclability.

“…Typically, a large number of hierarchical TMSs‐based composite structures, including ɑ ‐MnS@N, S‐NTC, NiS 2 ⊂PCF, Co 9 S 8 ‐QDs@NC, double‐helix structure FeS/CA, FeS 2 @C nanoboxes, and FeS@C nanospheres, have been prepared, and the enhanced sodium storage performances are delivered. It is worth noting that these composites are usually in powder form and need to be incorporated with extra polymer binders, which will introduce highly undesirable interfaces and thus probably negate the benefits of scrupulously designed architectures . Thereafter, it is proposed to further optimize the electrochemical performances by constructing self‐standing and binder‐free TMSs/carbon nanocomposites grown on conductive backbones.…”

Flexible self‐standing transitional metal sulfides (TMSs)/carbon nanoarchitectures have attracted widespread research interests for sodium ion batteries (SIBs), thanks to their enormous capability to address intrinsic issues of TMSs for SIBs applications. However, controllable synthesis of hierarchical hybrid structures is always laborious and involves complicated procedures. Herein, a simple yet general and scalable adsorption‐annealing strategy is first devised to finely construct core–shell carbon‐coated TMSs (TMSs@C, including Co9S8@C, FeS@C, Ni3S2@C, MnS@C, and ZnS@C) nanoparticles anchored on 3D N‐doped carbon foam (3DNCF) via the coordination and hydrogen‐bond adsorption. Benefiting from synergistic contributions from strong chemical affinity between nanodimensional TMSs and 3DNCF, efficient electronic/ionic transport channels, as well as a uniform carbon accommodating layer, the resulted self‐standing TMSs@C/3DNCF electrodes exhibit distinguished sodium storage performances, including large reversible capacities, high rate behaviors, and exceptional long‐span cycle stability in both half cells and flexible full devices. More significantly, the smart methodology developed holds huge promise for commercialization of binder‐free TMSs@C/3DNCF anodes toward advanced flexible SIBs.
