Pseudocapacitive materials are used for supercapacitor applications due to their exceptionally high capacitance and low cost. Good capacitive performance of the pseudocapacitive materials at high active mass loadings is vital for the development of the next generation of supercapacitor devices. This review describes recent advances in materials and nanotechnologies, which allows the development of advanced pseudocapacitive devices with high active mass. An important breakthrough is the discovery of novel dispersing and capping agents for the colloidal processing of nanoparticles. Particularly important are novel co‐dispersants that exhibit enhanced adsorption on materials of different types, such as inorganic nanoparticles, carbon nanotubes, and graphene. Conceptually new strategies are designed to fabricate coated particles. Recent innovations pave the way for the development of multifunctional redox‐active dopants‐dispersants and dopants‐oxidants to manufacture conductive polymer composites. Among the most important advances in nanotechnology is the development of template methods and heterocoagulation techniques for composite manufacturing. The progress in the design of novel surface modification techniques and materials, discovery of advanced anchoring groups, and development of liquid–liquid extraction allows agglomerate‐free processing of nanomaterials and composites. This review describes fundamental aspects of novel technologies and their applications in the manufacturing of pseudocapacitive devices for energy storage.

“…Interestingly, owing to the simple preparation method, the earth-abundant Cu7S4 nanocrystals have aroused extensive interest in the fields of electrocatalysis and photocatalysis. Although Cu7S4 has also been exploited in different photocatalytic applications, it is principally concentrated on degradation organics [66][67][68][69] and photothermal applications [70]. Notably, previous researches on Cu7S4 nanocrystals involved using them only as templates or semiconductors, rather than as co-catalysts.…”

“…[27,28] It has been proved that the electrochemical behavior of an electrode is affected by the morphology and structure of its materials. [29,30] Accordingly, scientists introduced different types of architectures such as nanowires, [31] nanosheets, [32] and nanotubes, [33] which reflected high Cs owing to their exclusive porous networks and remarkable surface area (SA). Among which, nanosheet arrays have reflected excellent potential as desirable electrode materials for ESDs owing to their exclusive structural merits containing rich reaction sites and shortened diffusion pathways for quick charge and discharge.…”

Electrode materials with unique nanoarchitecture, great conductivities, and desirable mechanical stabilities are essential for developing nearly all energy storage devices (ESDs). Herein, a low‐cost route for the fabrication of double‐layer CuCo2S4@Ni−Mo−S (CCS@NMS) nanosheet arrays as an advanced binder‐free positive electrode for supercapattery is presented. The CCS@NMS porous nanoarchitecture has the advantages of good ion diffusion and excellent electronic transport. Accordingly, when employed as battery‐type electrode in supercapattery device, the CCS@NMS electrode reflects amazing capacity (Cs) of 446.3 mAh g−1 (3213.6 F g−1) at 1 A g−1 and 375.8 mAh g−1 (2705.85 F g−1) at 18 A g−1, and 98.2 % of the Cs was still maintained at 6 A g−1 after 5000 cycles, which are higher than that of CCS electrode. Most importantly, using the CCS@NMS electrode as the positive electrode and active carbon (AC) as the negative electrode, the device indicates notable Cs of 66.8 mAh g−1 (160.4 F g−1), the considerable specific energy of 50.125 Wh kg−1 at a specific power of 750.04 W kg−1 and outstanding robustness of 96.8 %.
