Embedding of conductive Ag nanoparticles among honeycomb-like NiMn layered double hydroxide nanosheet arrays for ultra-high performance flexible supercapacitors

Construction of Binder‐Free, Self‐Supported, Hetero‐Core–Shell Honeycomb Structured CuCo2O4@Ni0.5Co0.5(OH)2 with Abundant Mesopores and High Conductivity for High‐Performance Energy Storage

“…The larger specific surface area of composite CCO@N 0.5 C 0.5 OH/NF provides a greater quantity of active sites for carriers, which is conducive to enhancing the energy storage performance of the electrode material, in electrochemical reaction. [73] The functional group information present in CCO/NF and CCO@N 0.5 C 0.5 OH/NF was characterized using Fouriertransform infrared spectroscopy (FTIR), and the results are displayed in Figure S8 (Supporting Information). The characteristic peaks at 657.65 and 558.27 cm −1 in the FTIR spectrum of CCO/NF correspond to the vibrations of CO 3+ ─O 2− tetrahedral sites and Cu 2+ ─O 2− octahedral sites in the spinel CCO, respectively.…”

Pulsed laser welding of macroscopic 3D graphene materials

“…6 Combining different characteristics into an integrated complex graphene system is technically compelling and has shown valuable in various applications. [29][30][31][32][33][34] For example, assembling carbon materials with opposite ion preferences into a single device has proven useful in hydro-voltaic technology. 35 In addition, integrating two graphene structures with distinct semi-conducting behavior (n-type doped and ptype doped) bears the potential to form graphene p-n junctions, the elementary entities for many electronic devices.…”

Metal‐Organic Frameworks and Their Derivatives‐Based Nanostructure with Different Dimensionalities for Supercapacitors

“…[25][26][27][28][29] Thus, it is a critical need for the development of novel electrode materials with high electrochemical performances. [30][31][32][33][34][35] To date, a large variety of nanocomposites and material systems have been extensively investigated to improve the supercapacitor properties and to fabricate hugely flexible and wearable supercapacitor electronics. [36][37][38][39][40] Among these, metal-organic frameworks (MOFs) have been extensively studied in various fields owing to their unique structure and intrinsic characteristics, which are hybrid crystalline materials with highly ordered pores formed by the coordination of metal ions/clusters and organic ligands endowed with electrons.…”
