“…As shown in Fig. 6(d), the ASC device performs well with a high energy density of 42.9 Wh•kg −1 at a power density of 800 W•kg −1 , and remains at 13.6 Wh•kg −1 when the power density increases to 8,000 W•kg −1 , outperforming the previously reported asymmetric cells [41][42][43][44][45][46]. Figure 6(e) demonstrates impressive cycling stability of Z-Co2NiSe4/ BWC//a-BWC ASC at a current density of 10 A•g −1 .…”

Developing suitable electrode materials for electrochemical energy storage devices by biomorph assisted design has become a fascinating topic due to the fantastic properties derived from bio-architectures. Herein, zephyranthes-like Co 2 NiSe 4 arrays grown on butterfly wings derived three-dimensional (3D) carbon framework (Z-Co 2 NiSe 4 /BWC) is fabricated via hydrothermal assembly and further conversion method. Benefiting from its unique structure and multi-components, the obtained Z-Co 2 NiSe 4 /BWC electrode for supercapacitor delivers an excellent specific capacitance of 2,280 F•g −1 at 1 A•g −1 . Impressively, the constructed asymmetric supercapacitor using Co 2 NiSe 4 /BWC as positive electrode and activated butterfly wings carbon as negative electrode acquires a high energy density of 42.9 Wh•kg −1 at a power density of 800 W•kg −1 with robust stability of 94.6% capacitance retention at 10 A•g −1 after 5,000 cycles. Moreover, the Z-Co 2 NiSe 4 /BWC as anode for sodium-ion batteries exhibits a high specific capacity of 568 mAh•g −1 at 0.1 A•g −1 and high cycling stability (maintaining 80.1% of the second cycle after 100 cycles). The outstanding electrochemical performances are ascribed to that the synergistic effect of bimetallic selenides and N-doped carbon improves electrochemical activities and conductivity. One-dimensional (1D) nanoneedles grown on 3D porous framework increase the exposure of redox-active sites, endow adequate transmission channels of electrons/ions, and guarantee stability of the electrode during charge/discharge processes. This study will shed light on the avenue towards extending such nanohybrids to excellent energy storage applications.

“…First, iron is the cheapest metal in the earth’s crust, and its reserves are extremely abundant. Furthermore, a large number of iron sulfides exist in natural minerals stably, such as pyrite, pyrrhotite, and troilite. − With these in mind, iron sulfides seem to be a suitable option for commercial ion batteries.…”

Potassium-ion batteries (PIBs) as a new electrochemical energy storage system have been considered as a desirable candidate in the post-lithium-ion battery era. Nevertheless, the study on this realm is in its infancy; it is urgent to develop electrode materials with high electrochemical performance and low cost. Iron sulfides as anode materials have aroused wide attention by virtue of their merits of high theoretical capacities, environmental benignity, and cost competitiveness. Herein, we constructed carbon-free crystal-like Fe 1−x S and demonstrated its feasibility as a PIB anode. The unique structural feature endows the prepared Fe 1−x S with plentiful active sites for electrochemical reactions and short transmission pathways for ions/electrons. The Fe 1−x S electrode retained capacities of 420.8 mAh g −1 after 100 cycles at 0.1 A g −1 and 212.9 mAh g −1 after 250 cycles at 1.0 A g −1 . Even at a high rate of 5.0 A g −1 , an average capacity of 167.6 mAh g −1 was achieved. In addition, a potassium-ion full cell is assembled by employing Fe 1−x S as an anode and potassium Prussian blue as a cathode; it delivered a discharge capacity of 127.6 mAh g −1 at 100 mA g −1 after 50 cycles.

“…However, the amount of nitrogen atoms is not sufficient to provide pyridinic N or pyrrolic N, which have the ability to anchor LiPSs. The N atom content can be increased through the surface polymerization of poly-pyrrole [107], poly-dopamine [108] or poly-aniline [109] on CENFs. Calcination can further turn N functional groups to different amounts of pyridinic N or pyrrolic N. Due to the different positions of N atoms in the carbon lattice, their adsorption capacity for LiPSs also differ.…”
