Enhancing Lithium-Air Battery Performance through CoPc@CNT Composites: Electrochemical Analysis and Insights

“…When the XPS spectrum (Fig. 9) obtained for the two composites is examined, the peaks for C1s, O1s and N1s were obtained at approximately 285 eV, 395 eV and 530 eV, respectively, and this agrees with the literature [64,65] .FIGURE 9 Electrochemical Tests…”

Recent Advances in Biomass Waste Derived Carbon Materials for Supercapacitors: A Review

“…On this basis, the present study also used AC@MnCu‐X composites as electrodes to assemble asymmetric SCs and successfully light up the light emitting diodes. In the other work, Zou and peers [ 92 ] prepared eggfruit‐derived porous carbon (EPC) loaded Co 3 O 4 composites (Co 3 O 4 @EPC) by solvothermal and calcination methods. SEM and XPS characterization results supported the successful synthesis of the composites.…”

In the other work, Zou and peers [92] prepared eggfruit-derived porous carbon (EPC) loaded Co Overall, carbon based composites derived from various biomass waste show favorable future in the field of SCs. Accordingly, the optimized performance of SCs electrode materials by researchers can further expand the exploration and application of BWDC composites.…”

Fabrication of honeycomb-structured composite material of Pr2O3, Co3O4, and graphene on nickel foam for high-stability supercapacitors

“…Metal oxides, particularly transition metal oxides such as MnO 2 , 10,11 RuO 2 , 12 Co 3 O 4 , [13][14][15][16] and others, are good electrode materials for pseudocapacitors due to their high theoretical specific capacitance and abundance. As a transition metal oxide Co 3 O 4 , has a very optimal theoretical specific capacitance as well as the benefits of environmental protection and low cost, making it an excellent material for supercapacitors.…”

“…As a transition metal oxide Co 3 O 4 , has a very optimal theoretical specific capacitance as well as the benefits of environmental protection and low cost, making it an excellent material for supercapacitors. 14,[16][17][18] Li et al claim that they created Co 3 O 4 /MnO 2 /Co(OH) 2 composite electrodes using a straightforward hydrothermal process along with the proper heat treatment and electrodeposition and that these electrodes had a high specific capacitance of 3022.2 F g À1 at a current density of 10 A g À1 . 18 Mn@Co 3 O 4 -MSs modified electrodes were created by Chen et al using solvothermal reaction and annealing treatment, and they displayed a high specific capacitance of 773 F g À1 at 1 A g À1 .…”
