Web1 day ago · After the electrochemical stability tested at a current density of 10 mA cm −2 in 1 M KOH, we further characterized the material by SEM ( Fig. S6 ), which revealed the excellent stability of the material. WebThe fabricated electrode delivered a high specific capacitance of 804 F g −1 at a current density of 1 A g −1 in 3 M KOH electrolyte. Nevertheless, the asymmetric assembly of the positive electrode with activated carbon showed poor cyclic stability, i.e., with 3000 charge-discharge cycles only capacitance retention of 81 % was achieved.
WebDue to the low capacitance value of electrode materials, the energy density of commercial supercapacitors is limited to 4–5 Wh·kg−1, lower than that of lead-acid batteries (25–35 Wh·kg −1) significantly, inhibiting the practical applications in the field of energy storage [7].
