“…The carbon coatings have several advantages, but here, it helps to a greater extent in avoiding the precipitation of the iron nanoparticles. Most of the Fe 2 O 3 microparticles, [ 173 ] Fe 3 O 4 nanoparticles and heterodoped iron oxide nanoparticles on flexible papers [ 174 ] were fabricated as negative electrodes only for battery capacitance and not is supercapacitors because the characteristics of such materials commonly support the transport of Li or Na ions. And in this year again, the carbon paper was tried as a substrate to develop Fe 3 O 4 nanoparticles for Fe–air batteries.…”

The progressive size reduction of electronic components is experiencing bottlenecks in shrinking charge storage devices like batteries and supercapacitors, limiting their development into wearable and flexible zero-pollution technologies. The inherent long cycle life, rapid charge-discharge patterns, and power density of supercapacitors rank them superior over other energy storage devices. In the modern market of zero-pollution energy devices, currently the lightweight formula and shape adaptability are trending to meet the current requirement of wearables. Carbon nanomaterials have the potential to meet this demand, as they are the core of active electrode materials for supercapacitors and texturally tailored to demonstrate flexible and stretchable properties. With this perspective, the latest progress in novel materials from conventional carbons to recently developed and emerging nanomaterials toward lightweight stretchable active compounds for flexi-wearable supercapacitors is presented. In addition, the limitations and challenges in realizing wearable energy storage systems and integrating the future of nanomaterials for efficient wearable technology are provided. Moreover, future perspectives on economically viable materials for wearables are also discussed, which could motivate researchers to pursue fabrication of cheap and efficient flexible nanomaterials for energy storage and pave the way for enabling a widerange of material-based applications.

“…S8, † the P-FeNi/ NC@G catalyst exhibits the lowest charge transfer resistance as compared with FeNi-MOFs and FeNi-MOF-pyrolysis, which can be attributed to the efficient charge transfer pathways generated by graphene during the ORR and OER process. 41 Finally, the ORR and OER polarization curves recorded before and aer 1000 CV cycles are analyzed to assess the stability of P-FeNi/ NC@G catalyst, as shown in Fig. S9.…”

“…Among various anode materials, Fe 3 O 4 receives widespread attention because of its high theoretical capacity (926 mAh g −1 ) [8], easy availability, and environmental benignity [9,10]. At the same time, some disadvantages, such as poor conductivity, serious volume expansion, and poor cycle stability, also limit its application in high-performance LIBs [11,12]. Many strategies have been used to alleviate and restrain the above shortcomings.…”

The development of facile preparation methods and novel three-dimensional structured anodes to improve cycling stability of lithium ion batteries (LIBs) is urgently needed. Herein, a dual-network ferroferric oxide/nickel oxide (Fe3O4/NiO) anode was synthesized through a facile dealloying technology, which is suitable for commercial mass manufacturing. The dual-network with high specific surface area contains a nanoplate array network and a bimodal nanoporous urchin network. It exhibits excellent electrochemical performance as an anode material for LIB, delivering a reversible capacity of 721 mAh g−1 at 100 mA g−1 after 100 cycles. The good lithium storage performance is related to the ample porous structure, which can relieve stress and mitigate the volume change in the charge/discharge process, the interconnected porous network that enhances ionic mobility and permeability, and synergistic effects of two kinds of active materials. The paper provides a new idea for the design and preparation of anode materials with a novel porous structure by a dealloying method and may promote the development of the dealloying field.
