As a result of these merits, Co-doped 尾-MnO 2 annealed at 500掳C displayed higher electrochemical performance for using as the anode of Li-ion batteries. At 100mA/g, the discharge capacity was as high as 648 mAh/g for the 2nd cycle, and after 200 cycles, 68% capacity was retained....

rivaling expensive RuO2or MnO2pseudo-capacitors. The new electrodes also exhibit excellent cyclic stability without capacitance loss after 10,000 cycles in both acidic and basic electrolytes at a high charge current of 5 A g−1. This work provides a new approach for designing high-performanc...
As such, the synergistic effects of the nitrogen and fluorine co- doping enable the CMs with an ultrahigh specific volumetric capacitance up to 521 F cm À 3 in H2SO4, significantly greater than other carbon materials and rival to RuO2 or MnO2 composites. The CM-NF electrode exhibits an ...
Here, we demonstrate ultrahigh volumetric capacitance of 521Fcm3in aqueous electrolytes for non-porous carbon microsphere electrodes co-doped with fluorine and nitrogen synthesized by low-temperature solvothermal route, rivaling expensive RuO2or MnO2pseudo-capacitors. The new electrodes also exhibit ...
In addition, the transition metal oxides and bimetallic oxides (CuO [14], MnO2 [15], CoFe2O4/C [16], ZnCo2O4/NCNTs [17], etc.) also exhibited excellent ability in OER electrocatalysis, which are even comparable to the well-recognized IrO2 and RuO2. Furthermore, bimetal hydroxide has ...
