“…But, the highest iodine utilization is only possible in I 3 − /I − form in solution due to the most increased reactive components, which suffers from diffusion issues.

Aqueous rechargeable zinc–iodine batteries (ARZIBs) represent a promising form of sustainable energy storage, having highly abundant and environmentally workable elements. The low utilization of solid iodine and self‐discharge due to the diffusive properties of the soluble polyiodides in aqueous media hamper the stability and device design. The concept of building a solid‐state ARZIB with self‐discharge control by limiting iodide diffusion employing solid–gel reactions with water‐based gel‐embedded I3−/I− in block copolymer bearing highly active iodine components is demonstrated. The catholyte gel has an amphiphilic property that provides high solubility for iodine and better ionic conductivity from the cubic microcrystalline self‐assembled structures. This gel prevents long range iodide ion diffusion in multilayer self‐assemblies of the catholyte followed by the gel electrolyte layer due to self‐trapped polyiodides at the core–shell interface and inside the hydrophobic core of micelles. By contrast, positive zinc ions easily diffuse through the hydrophilic poly(ethylene oxide)‐water‐rich channels. This solid matrix results in a discharge capacity of 210 mAh g−1 (at 1 C rate) and stability with a retaining capacity of 94.3% after 500 cycles, including self‐discharge protection. The flexible module device shows excellent flexibility during deformations and the ability to power gadgets with stable performance.

One of the key challenges for the development of lithium‐ion batteries is the preparation of high‐performance anode materials. In this paper, a micro/nanostructured Si@SnS2‐rGO composite is reported in which Si nanoparticles with a particle size of 30 nm are electrostatically anchored on a 3D reduced graphene oxide (rGO) network and mixed with SnS2. The step‐wise lithiation/delithiation of SnS2 provided space‐constraining effects to accommodate volume expansion and particle aggregation, thereby alleviating the volume expansion of Si during cycling as well as enhancing the structural stability, whereas the rGO in the 3D network stabilized the composite. The composite had a high specific capacity of 1480.1 mAh g−1 after 200 cycles at a current density of 200 mA g−1 and a high stability at rates of 200–3000 mA g−1. The capacity attenuation after cycling was only 89.18 %. A stable specific capacity (425.5 mAh g−1) was achieved after 600 cycles at a current density of 3000 mA g−1. Therefore, the micro/nanostructured Si@SnS2‐rGO composite is a promising anode material for use in lithium‐ion batteries.

“…Additionally, a 3D graphene foams with the introduction of N, S doping through the thermal decomposition of thiourea was proposed. [18] Heteroatom doping would regulate the electronic structure and enlarge specific surface area of pristine carbon framework, improving its adsorption/desorption capacity toward iodine species. Compared with the battery using commercial Zn plate anode, the aqueous ZIB with the N, S-enriched carbon scaffold exhibited faster iodine redox kinetics, better reversibility, and outstanding cycling performance of 81% capacity retention after 500 cycles (Figure 9c,d).…”

Zinc–iodine batteries (ZIBs) are regarded as promising energy storage devices due to their high performance and low cost. Nevertheless, their wide application is mainly limited by the preparation of iodine‐based cathode and dendrite‐free zinc anode. Flexible carbon fibers have attracted tremendous attention, due to their iodine encapsulation properties. This characteristic is a result of their porous structure, large surface area, and excellent intrinsic properties. With the development of carbon fibers for loading iodine, the surface properties can be rationally modulated via heteroatom doping and combination with various polymers can enhance battery performance. In this review, recent research advances on the functionalization of carbon fibers for ZIBs are summarized, with special focus on the pore size of carbon fibers, the species, and content of doping elements, and the selection of targeted polymers toward the loading of iodine. Finally, the prospects and future challenges of ZIBs based on carbon fibers are presented. The review aims to provide the basic guides for designing advanced iodine‐based electrode materials on the basis of carbon fibers with both compositional advantages and microporous structure to achieve high‐performance ZIBs.
