Electrochemical performance of Bi2O3 decorated graphene nano composites for supercapacitor applications

Facile preparation of commercial Bi2O3 nanoparticle decorated activated carbon for pseudocapacitive supercapacitor applications

“…Activated carbons have displayed great potential as e cient electrodes for EDLC type supercapacitors due to high micro/mesoporousity, their high speci c unique pore structure for e cient ion diffusion and low cost [13]. Although porous activated carbon (AC) as a supercapacitor has a high-power density and a long cycle life it has relatively low speci c capacitance [14]. Heteroatoms in the porous carbon networks improve surface wettability of the electrode and contribute additional pseudo-capacitance to the total capacitance in the active carbon derivatives [14][15][16].…”

Solvothermal preparation of spherical Bi2O3 nanoparticles uniformly distributed on Ti3C2Tx for enhanced capacitive performance

“… 23 Recent studies have shown that Bi 2 O 3 can be used as an electrode material for supercapacitors. Furthermore, its electrochemical performance has been improved by combining with other electrode materials based on carbon and transition metal oxides, such as carbon nanotubes, 24 graphene 25 and MnO 2 . 26 Thus, we expect that Bi 2 O 3 would show an affinity for Ti 3 C 2 T x -based materials, which has not yet been reported in literature.…”

Facile Synthesis of Mn0.68Bi0.32OCl Mix-Crystals And Its Supercapacitive Behavior

“…The two-layer capacitor consists of activated carbon electrode material, and pseudocapacitive supercapacitors include metal oxide electrode materials and polymer electrode materials. Mn and Bi are environmentally friendly and inexpensive, widely used in the preparation of supercapacitors, and the Mn 3 O 4 [1], MnO [2], MnOx [3], Mn 2 O 3 [4], Bi 2 O 3 [5][6][7][8], BiOCl [9], (Cu)BiOCl [10], and BiOBr [11] supercapacitors have been prepared for supercapacitors.…”
