“…For improving the energy density at high power density and at the same time retained the prolonged cycle life of the supercapacitor, two ways of approaches are there; one is an energy density of supercapacitor is directly proportional to square of the operating voltage (i. e. E = 1 = 2 CV 2 ) where V is the potential window (V) and C is the specific capacitance (F g À1 ) to increase the larger operating voltage window by employing organic electrolytes (2.5-4.0 V) instead of aqueous electrolytes (~1.25 V). [12] Another way is to develop hybrid supercapacitor is the transition from a battery type electrode to a capacitor type electrode offer the advantage of both supercapacitor (high specific capacitance, long cycle life) and the advantage of batteries (high energy density and working voltage). [13] However, the various morphology of electrode material is also play a vital role, because such electrodes should enhance the energy density of the supercapacitor without sacrificing its power density and, mostly several research are focused on the lithiumion intercalating based electrode materials, such as LiMn 2 O 4 , Li 2 Mn 4 O 9 /AC, Li 4 Mn 5 O 12 , and Li 4 Ti 5 O 12 has the electrode materials for the fabrication of hybrid supercapacitor applications.…”

Electrospun high‐voltage spinel‐typeLiNd0.01Mn1.99O4 nanofibers (LNdMO NFs) were successfully prepared through the electrospinning technique. The thermal behavior of the electrospun precursor fibrous mat was assessed by thermogravimetric/differential thermal analysis. The crystallite structure and phase purity of Nd3+‐doped LiMn2O4 was confirmed by X‐ray diffraction studies. The chemical structure of the electrospun LNdMO NFs was characterized by Raman spectroscopy studies. The morphology of the nanofibers was examined by using field‐emission scanning electron microscopy. A Li‐ion capacitor (LIC) coin cell was fabricated by using high‐voltage insertion LNdMO NFs as the cathode and black pearl carbon as the anode with electrospun PVdF membrane containing 1 M LiNO3 as the separator and electrolyte. The electrochemical performance of the assembled LIC coin cell was characterized by using cyclic voltammetry, galvanostatic charge−discharge and electrochemical impedance spectroscopy. The LIC was capable of operating over wide potential window of 1.6 V with excellent capacitance retention of 86 % even after 2500 continuous galvanostatic charge−discharge cycles at a constant current density of 1 A g−1. Furthermore, LIC delivered an energy density of 17 Wh kg−1 and a power density of 397 W kg−1. Moreover, these results show that Nd3+‐doped LiMn2O4 NFs can be considered a promising electroactive cathode material for LICs.

“…In the low-frequency region, the Nyquist points becomes a straight line corresponding to the impedance of the solid phase diffusion. [54] At higher potential (1.5-2.5 V), the semicircle that is not obvious represents the interfacial resistance between the electrode and the electrolyte. And the tilted straight line attributes to Warburg impedance.…”

Prussian blue analogue KxMnFe(CN)6·yH2O (m‐KMHCF) nanocubes with an average edge length of about 60 nm were synthesized by a simple hydrothermal reaction involving methanol. The microscopic size of m‐KMHCF nanocubes could be easily reduced to less than 100 nm as methanol was added to the reaction, over a long range of reaction temperatures and reaction times. As anode material for lithium‐ion batteries, the m‐KMHCF electrode delivered a high specific capacity of over 900 mAh g–1 at a current density of 100 mA g–1 after 50 cycles. In addition, it provided stable rate capability and lithium storage performance at the high current density of 382.3 mAh g–1 at 5000 mA g–1. It is worth noting that the capacity continued to rise during the galvanostatic charge‐discharge, and the specific capacity increased after charging and discharging at the large current. This phenomenon and the excellent electrochemical performance are mainly derived from the smaller microscopic size, which further led to crystal particle refinement during charge‐discharge.

“…Specific capacitance (C s ) values of 38 F g −1 and 39 F g −1 were registered through cyclic voltammetry and charge/discharge experiments performed at 70 °C, wherein the typical, rectangular CV profile was only observed at higher temperatures due to the SPE transitioning towards a GPE (Figure B). Electrospinning is an alternative route to prepare solid polymer electrolyte materials, wherein Solarajan and colleagues designed electrospun PVDF‐HFP/MMT mats as solid electrolytes in Li‐ion capacitors (Figure C). Advantages of the this technique and clay incorporation include the following: production of interconnected pores and channels allowed for fast ion diffusion, and clay material avoided any thermal shrinkage of the electrospun mats which is essential to prevent capacitor short circuit.…”
