“…This remarkable capacitive achievement is assigned to the adequate mechanical friction and electrical attachment with the substrate, superior contact area with electrolyte and prevented structural pulverization through the cyclic process. To clearly indicate various parameters on performance, a series of typical Ni 3 S 2 nanostructures with different morphologies obtained by different synthesis methods is shown in Table 1 [147][148][149][150][151][152][153][154][155][156].…”

Supercapacitors are favorable energy storage devices in the field of emerging energy technologies with high power density, excellent cycle stability and environmental benignity. The performance of supercapacitors is definitively influenced by the electrode materials. Nickel sulfides have attracted extensive interest in recent years due to their specific merits for supercapacitor application. However, the distribution of electrochemically active sites critically limits their electrochemical performance. Notable improvements have been achieved through various strategies such as building synergetic structures with conductive substrates, enhancing the active sites by nanocrystallization and constructing nanohybrid architecture with other electrode materials. This article overviews the progress in the reasonable design and preparation of nickel sulfides and their composite electrodes combined with various bifunctional electric double-layer capacitor (EDLC)-based substances (e.g., graphene, hollow carbon) and pseudocapacitive materials (e.g., transition-metal oxides, sulfides, nitrides). Moreover, the corresponding electrochemical performances, reaction mechanisms, emerging challenges and future perspectives are briefly discussed and summarized.

“…[25][26][27][28][29][30][31][32][33][34] Rechargeable batteries, for example, store solar and wind energy and are considered one of the most efficient energy storage devices. [35][36][37][38][39] On the other hand, the charge storage system of rechargeable batteries depends on the intercalation and deintercalation of host cations (Li + , K + , Na + , H + , and so on) [40,41] . The electrode content greatly limits the charge/discharge rates (power density) and lifetime (cyclability).…”

Due to their promising properties such as low corrosion resistance, excellent strength, high-temperature operation, simple formability and machining, and, most importantly, cost-effectiveness in the industry, honeycomb-based heterostructures have been widely used as energy storage and conversion systems for decades. Despite their low density, honeycomb structures also have strong out-of-plane compression and shear properties, resulting in very high unique strengths. The honeycomb-based molded structure, which was inspired by bee honeycombs and provides a material with low density and high out-of-plane compression and shear properties, has found widespread use and now plays a critical role in energy conversion and storage technologies such as lithium-ion batteries, solar cells, and supercapacitors. These materials have a lot of promise in terms of addressing and environmental concerns regarding power sources at a time when global energy demand is skyrocketing. In light of this, we contend in this research paper that complex honeycomb-based architectures outperform conventional simple 2D designs in a wide variety of technological applications. We also go into the different synthetic methods used to make honeycomb structures and look at how these novel materials may be used for long-term electrochemical energy transfer and storage. Finally, the current challenges and opportunities for the construction of honeycomb systems are discussed, as well as new research directions.

As an intermediate step during energy usage, supercapacitors with superior power density, long‐term cycling stability, and moderate energy density have attracted immense interest as a facile route to use energy in a clean, efficient, and versatile manner in smart grid applications, as well as portable devices and other applications. Currently, the major drawback of supercapacitors is the low energy density. Electrode materials are the key components determining the cell performance. Great research efforts are made to develop nanostructured electrode materials with high performance. On the other hand, integrating supercapacitors with other applications have led to the emergence of many new types of multifunctional supercapacitors, which are attractive for a myriad of applications. The current understanding on charge/discharge mechanisms of electric double layer capacitors and pseudo‐capacitors is discussed along with recent development in designing nanostructured electrode materials by structure/morphology engineering, doping, and crystal structure controlling. Achievements in multifunctional supercapacitors like flexible supercapacitors, all‐solid‐state supercapacitors, self‐healing supercapacitors, electrochromic supercapacitors, self‐chargeable supercapacitors, and supercapacitors integrated with sensors are illustrated. Finally, opportunities and challenges in developing high performance and multifunctional supercapacitors are proposed.
