Designing a novel, efficient, and cost-effective nanostructure with the advantage of robust morphology and outstanding conductivity is highly promising for the electrode materials of high-performance electrochemical storage device. In this paper, a series of honeycombed perovskite-type Sr-doped LaNiO3 nanosheets with abundant porous structure were successfully synthesized by accurately controlling the Sr-doped content. The study showed that the optimal LSNO-0.4 (La0.6Sr0.4NiO3-δ) electrode exhibited excellent electrochemical performance, which showed a high capacity of 115.88 mAh g−1 at 0.6 A g−1. Furthermore, a hybrid supercapacitor device (LSNO//AC) based on LSNO-0.4 composites and activated carbon (AC) showed a high energy density of 17.94 W h kg−1, a high power density of 1600 W kg−1, and an outstanding long-term stability with 104.4% capacity retention after 16,000 cycles, showing an excellent electrochemical performance and a promising application as an electrode for energy storage.

Carbon-modified fibrous structures with high biocompatibility have attracted much attention as supercapacitors due to their low cost, sustainability, abundance, and excellent electrochemical performance. However, some of these carbon-based materials suffer from low specific capacitance and electrochemical performance, which have been significant challenges in developing biocompatible electronic devices. In this regard, several studies have been reported on the development of 3D carbon-based micro architectures that provided high conductivity, energy storage potential, and 3D porosity frameworks. This study reports manufacturing of microfluidic Alginate hollow microfiber modified by water-soluble modified Graphene (BSA-Graphene). These architectures successfully exhibited conductivity enhancement conductivity of about 20 times more compared to Alginate hollow microfibers, and without any significant change in the inner-dimension values of hollow region (220.0 ± 10.0 µm) in comparison with pure alginate hollow microfibers. In the presence of Graphene, more obtained specific surface permeability and active ion adsorption sites could successfully provide as shorter pathways. These obtained continuous ion transport networks resulted in improved electrochemical performance. These desired electrochemical properties of the microfibers make Alginate/Graphene hollow fibers an excellent choice for further use in the development of lightweight flexible supercapacitors with scalable potential to be used in intelligent health electronic gadgets.
