Rational design of A-CNTs/KxMnO2 and Ti3C2Tx/MoO3 free-standing hybrid films for flexible asymmetric supercapacitor

Facile Fabrication of Iron Cobalt Sulfide Nanoparticles within N-Doped Graphene for High-Performance Supercapacitors

“…The assembled ASC device achieves an extraordinary energy density of 79.3 Wh kg −1 at a power density of 804 W kg −1 . Even at a high power density of 15,069 W kg −1 , the energy density of the ASC device still keeps 47.3 W h kg −1 , which is predominant in comparison with the previously reported ASCs, such as CCSe-HSs//AC (53.86 W h kg −1 at 800 W kg −1 ), 53 (NiOH) 2 /rGO//AC (39.64 W h kg −1 at 1962 W kg −1 ), 49 NiZn-LDH@NiCoSe 2 //AC (49 W h kg −1 at 160 W kg −1 ), 51 NiO/CeO 2 //Bi-Ni-O (78 W h kg −1 at 201 W kg −1 ), 54 at 863 W kg −1 ), 55 and NiCoFe-LDH/Ti 3 C 2 //rGO (54.4 W h kg −1 895 W kg −1 ). 56…”

Tightly intercalated Ti3C2Tx/MoO3−x/PEDOT:PSS free-standing films with high volumetric/gravimetric performance for flexible solid-state supercapacitors

“…10 However, the van der Waals interactions and hydrogen bonding between adjacent Ti 3 C 2 T x sheets can lead to severe self-stacking problem, which will largely reduce the contact area between the Ti 3 C 2 T x sheets and the electrolyte, thus deteriorating the electrochemical performance of Ti 3 C 2 T x . 11,12 To overcome this drawback, the main method adopted is the introduction of intercalators between Ti 3 C 2 T x sheets, such as organic substances, 13,14 carbon materials, 15,16 transition metal oxides, 17,18 conductive polymers, 19,20 etc.…”

A tough, anticorrosive hydrogel consisting of bio-friendly resources for conductive and electromagnetic shielding materials

“…However, EMI polymer films have a limited range of applications, single-use conditions, and poor bio-friendliness, which need attention. 18,[21][22][23][24] Therefore, hydrogels with excellent flexibility and high moisture content are one of the best candidates for next generation EMI materials.…”
