Considerable efforts are underway to rationally design and synthesize novel electrode materials for high-performance supercapacitors (SCs). However, the creation of suitable materials with high capacitance remains a big challenge for energy storage devices. Herein, unique three-dimensional (3D) ZnO hexagonal cubes on carbon cloth (ZnO@CC) were synthesized by invoking a facile and economical hydrothermal method. The mesoporous ZnO@CC electrode, by virtue of its high surface area, offers rich electroactive sites for the fast diffusion of electrolyte ions, resulting in the enhancement of the SC’s performance. The ZnO@CC electrode demonstrated a high specific capacitance of 352.5 and 250 F g−1 at 2 and 20 A g−1, respectively. The ZnO@CC electrode revealed a decent stability of 84% over 5000 cycles at 20 A g−1 and an outstanding rate-capability of 71% at a 10-fold high current density with respect to 2 A g−1. Thus, the ZnO@CC electrode demonstrated improved electrochemical performance, signifying that ZnO as is promising candidate for SCs applications.

“…With the development of a global economy, environmental issues and the continuous increased demand for clean and sustainable energy, energy conversion/storage devices have developed significantly in recent years. [1][2][3] Supercapacitors and secondary batteries have been widely and deeply studied. Compared with secondary batteries, supercapacitors storage charge by fast and reversible faradaic reactions occurred at the electrode-electrolyte interface, have high power density of about 10 kW kg À 1 and ultralong lifetime (~10 5 times), but they possess low energy density (< 20 Wh kg À 1 ), which limit its widespread applications.…”

Controllable Intercalated Polyaniline Nanofibers Highly Enhancing the Utilization of Delaminated RuO₂ Nanosheets for High‐Performance Hybrid Supercapacitors

Ruthenium oxide (RuO2) and polyaniline (PANI) are attracting extensive attention as electrode materials due to their remarkable pseudocapacitance. However, RuO2 suffers from low utilization and PANI sustains poor stability. Herein, both defects were optimized by designing intercalated‐structure PANI/RuO2 composites, which were fabricated for the first time by controllable chemical polymerization of aniline on the delaminated RuO2 nanosheets. Intercalated PANI nanofibers not only highly prevent the RuO2 nanosheets from their reassembling as well as increase the interlayer spacing among RuO2 nanosheets but also alleviate the swelling/shrinking of PANI during charge‐discharge progress. In comparison to the pristine RuO2 nanosheets, the obtained intercalated structure is beneficial for creating channels for better ion transfer and electron transport, which leads to a high‐efficiency utilization of RuO2 nanosheets. The optimized PANI/RuO2‐38 electrode with a RuO2 content of 61.7 wt% shows the highest utilization of 72.1 % of RuO2, resulting in the highest specific capacity of 816 F g−1. The asymmetric supercapacitor PANI/RuO2//AC offers a high energy density of 25.7 Wh kg−1 at 375 kW kg−1, further indicating a good potential as energy‐storage device.
