Rational design of meso-/micro-pores for enhancing ion transportation in highly-porous carbon nanofibers used as electrode for supercapacitors

Recent Advancements in Electrochemical Deposition of Metal‐Based Electrode Materials for Electrochemical Supercapacitors

“…By increasing C S and cell potential ( ~V), and simultaneous decrease of ESR (R S ), characteristics of ES can be improved. As demonstrated in equations (9)(10)(11), the energy and power density are directly proportional to the square of cell voltage. Thereby, an increase in cell voltage has more contribution than an increase in capacitance and a decrease in ESR on energy density and power density.…”

“…Among these, ESs (also known as supercapacitors/ultracapacitors) [9,10] have attracted more attention due to their various advantages over other energy storage devices. [11,12] The significant benefits of ESs include high power density, long life expectancy (> 10 4 cycles), long shelf life, a wide range of operating temperatures, high efficiency, environmental friendliness, and a simple fabrication process. [13][14][15][16] Generally, supercapacitors are characterized by an extremely high power capability, up to 2 kW/kg, with short charging and discharging times in the range of seconds and a long lifetime.…”

A metal–organic framework approach to engineer mesoporous ZnMnO3/C towards enhanced lithium storage

“…The diffraction peaks at 18.353, 30.272, 35.670, 43.472, 53.886, 57.322 and 62.963 were indexed to ZnMnO 3 (PDF# 19-1461). 26 The sample could match well with the cubic phase of ZnMnO 3 (PDF# 19-1461), and we were able to observe from the graph an obvious carbon peak, 27 which would preliminarily indicate that the synthesized sample was ZnMnO 3 /C, while no other peaks were observed, which indicated that the purity of the product was very high. 28 In order to further conrm the structural data of ZnMnO 3 /C, Raman spectroscopy investigation was performed (Fig.…”

Self-Assembled Polyaniline/Ti3C2Tx Nanocomposites for High-Performance Electrochromic Films

“…In addition, the electrodes with different MXene contents had different slopes of the straight lines in the low frequency region. Compared with the pure PANI electrode, 7PANI/3MXene had a steep slope in the low frequency region, indicating that the composite electrode has higher ion conductivity and shorter ion diffusion path [53]. In order to quantify the different parameters of the PANI/MXene electrode EIS test, we fit the EIS data into an equivalent circuit, as shown in (Figure S6).…”
