Designing two dimensional nanoarchitectured MoS2 sheets grown on Mo foil as a binder free electrode for supercapacitors

A High‐Energy Aqueous Sodium‐Ion Capacitor with Nickel Hexacyanoferrate and Graphene Electrodes

“…The core level spectrum of C 1s (Figure (C)) and N 1s (Figure (D)) revealed the presence of C and N components in cyano bridged network frame of Ni‐HCF. Further, the surface area and pores present in the electrode material plays a critical role on their electrochemical properties . The Nitrogen adsorption–desorption isotherm and pore size distribution curves of Ni‐HCF nanostructures was examined and the data is shown in Figure S2 (a and b).…”

A high energy density asymmetric supercapacitor from ultrathin manganese molybdate nanosheets

“…The above works both used the polymer binder in the electrode leading to lower performance which ascribe to that binders and other additives used in the electrode could lead to the decrease of conductivity and the addition of dead weight of an electrode [24,25]. Binder free electrode has remarkable advantages, such as better conductivity of the active materials with current collector, faster electron diffusion [26], and higher rate capability [27,28]. Later, Cao et al reported MnMoO 4 ·4H 2 O nanoplates grown directly on Ni foam as a binderfree electrode presented a great specific capacitance of 2300 F g −1 at 4 mA cm −2 and 92% of the initial specific capacitance remained after 3000 cycles at a scan rate of 5 mV s −1 [29].…”

Facile synthesis of maguey-like CuCo2O4 nanowires with high areal capacitance for supercapacitors

“…However, the use of conducting additive and binder unavoidably increases the undesirable interparticle resistance which decreases the efficiency of electron transport among active materials. Comparing to the powder electrode, it was shown that direct growth of electrode materials arrays on conductive substrates [29][30][31][32][33] could conquer the shortcoming compared to the power electrode. For example, CuCo 2 O 4 nanograss on a Cu foam substrate has hold specific capacitances of 796 F g -1 at 2 A g -1 [17].…”
