Efficient coupling of MnO2/TiN on carbon cloth positive electrode and Fe2O3/TiN on carbon cloth negative electrode for flexible ultra-fast hybrid supercapacitors

Abstract: MnO2 ultrathin nanosheet arrays and Fe2O3 nanoparticles are fabricated on carbon based TiN nanowires to produce binder-free and core–shell positive and negative electrodes for a flexible and ultra-fast hybrid supercapacitor.

“…Figure 2c shows the Mn 2p spectrum of α-MnO 2 @CNTs/CC, revealing peaks at 654.2 eV for Mn 2p 1/2 and 642.5 eV for Mn 2p 3/2 of MnO 2 . The satellite peak (sat) is related to α-MnO 2 , consistent with previous studies and further confirming the formation of MnO 2 [28]. The H-O-H (531.9 eV) and Mn-O-H (530.2 eV) peaks in Figure 2d of α-MnO 2 @CNTs/CC are attributed to the hydroxyl groups and absorbed water, respectively [30][31][32].…”

“…All in all, the potential time curves in Figure 6b show a stable output potential of 467 mV after 4 h and it remains at about 385 mV after 21 h, which is comparable to previous studies [46]. The relationship between impedance data and frequency of complex capacitance model is essential to analyze the supercapacitor electrodes [28]. Figure 6c depicts the relationship between the real part of the capacitance C (ω) with the frequency of CNTs/CC, α-MnO 2 /CC, and α-MnO 2 @CNTs/CC, according to Equations S1, S2, and S3.…”
