“…The former was ascribed to sp2 hybridized carbon, while the latter corresponded to sp3 hybridized carbon, forming chemical bonds with oxygen or other heteroatoms, specifically corresponding to C=O and C−C bonds. Additionally, the C spectrum also showed characteristic plasmon loss features associated with graphene, confirming the successful compositing of rGO [27,28] …”

Construction of prosperous morphology and incorporation of multiple metals with synergistic effect can effectively enhance the electrochemical performance of electrode materials. Herein, transition metal (Ni, Co, Mo) sulfides (NCM‐DI, NCM‐DI‐NTA, NCM‐EG, NCM‐EG‐NTA, NCM‐Mix‐NTA) were synthesized, and the morphology was adjusted by incorporating metal ligand and altering the solvent atmosphere. The addition of ligand nitrilotriacetic acid (NTA) endowed the formation of cross‐linked network (NCM‐DI‐NTA, NCM‐EG‐NTA, NCM‐Mix‐NTA), and the as‐prepared materials generated in mixed solvent (NCM‐Mix‐NTA) displayed smaller size. Materials with NTA added (NCM‐DI‐NTA, NCM‐EG‐NTA, NCM‐Mix‐NTA) displayed higher specific capacity (754, 943 and 1206 F g−1, respectively), which is much higher than NCM‐EG (909 F g−1) and NCM‐DI (331 F g−1). After doped with rGO, the materials (NCM‐Mix‐NTA‐rGO) exhibited a specific capacity of 1984 F g−1 at 1 A g−1. When assembled into asymmetric supercapacitors, it delivered the energy density of 61.6 Wh kg−1 at a power density of 901.4 W kg−1, and maintained the 86.5 % of their initial capacity even after 5000 cycles.

“…10,21,22 Even though the carbonaceous electrodes possessed a high surface area, their potential applications were significantly limited due to their toxic nature and higher charge transfer resistance. 23,24 To achieve a higher E d and specific capacitance (C sp ), it was necessary to employ chalcogenides/layered double hydroxides/hydroxides/transition metal oxides, which undergo various reversible faradaic redox reactions. However, the lower surface area and inadequate wetting of the surface/ electrolyte interface hindered their overall electrochemical performances and subsequent applications.…”

The rise of flexible and wearable electronics has spurred advancements in printed, flexible micro-supercapacitors for energy storage. This study presents the fabrication of flexible micro-supercapacitors using a novel nanocomposite of tin dioxide grown on layered reduced graphene oxide through one-pot in situ synthesis. The conductive functional ink, formulated by mixing the nanocomposite, is effectively utilized in screen-printing technology. The resulting micro-supercapacitors, particularly the SG-1 variant, demonstrate impressive electrochemical performance. The nanocomposites show exceptional versatility across various electrolytes, including alkaline, acidic, and quasi-gel electrolytes with a polyvinyl alcohol matrix infused with potassium hydroxide. An in-depth comparison of their efficacy in these electrolytes highlights the most suitable configurations for optimal performance. At a scan rate of 5 mV s−1, SG-1 achieves areal capacitances of 148.7 mF cm−2 and 87.7 mF cm−2 in the 1 M KOH and polyvinyl alcohol infused with 1 M KOH quasi-gel electrolyte. Additionally, SG-1 in the gel electrolyte demonstrates remarkable energy density of 11.7 mWh cm−2 at power density of 490 mW cm−2. Notably, the fabricated micro-supercapacitors exhibit excellent capacitive retention of 89.5% even after undergoing 5000 cycles of charge–discharge, underscoring their robustness and long-term stability for practical applications in flexible and wearable electronics.
