“…The electrochemical performance of the electrodes has been investigated by cyclic voltammetry (CV) (Figure 35a,b) with the voltage range of 0-2.5 V at four different scan rates of 5, 30, 50, and 100 mV/s. The CV curve of electric double layer capacitor is rectangular [131,132]. However, the CV curve of CNT/CP (Figure 35a) electrodes presented a reduction peak without oxidation peak.…”

Lithium ion batteries (LIB) and supercapacitors (electric double-layer capacitors (EDLCs) and lithium ion capacitors (LIC)) are the most energy storage service for mobile application. Lithium ion batteries are currently the most popular type of battery for powering portable electronic devices and are growing in popularity for defense, automotive and aerospace applications. The investigation of supercapacitors (SCs) has also achieved significant progresses. Although they have shown remarkable commercial successes, the electrodes and their constituent materials are still the subject of intensive research. Our research focused on a new type of carbon nanotube-cellulose composite materials as current collector of LIBs and as electrodes of SCs for improving and enhancing the energy/ power density and cyclic performance of them. Carbon nanotubes (CNTs) have been widely used as conductive agent for both anodes and cathodes to replace super carbon black to satisfy the multifunctional requirements for LIBs. Applications of carbon nanotubes (CNTs) in lithium ion battery and supercapacitorLithium ion batteries (LIBs) and supercapacitors (SCs) are considered to be the most promising energy storage devices because of their relatively high energy density, good cycle performance, power performance, longer service life, and green environmental characteristics. LIBs have a broad application prospects in portable electronic equipment, electric vehicles, and hybrid vehicles [1,2].The electrodes of LIB commonly use copper foil or aluminum foil as a current collector, and the active material is coated on the current collector. Carbon nanotubes (CNTs) have unique features of one-dimension, large surface area and high conductivity, which contribute to electrochemical performance of LIBs and SCs [3][4][5]. Thus, many investigations in terms of electrode materials are focused on CNTs. Compared with aluminum foil or copper foil, metal-free current collector is a research hotspot, CNT film or cellulose papers used as negative electrode, or anode current collector was applied in flexible lithium ion battery in many researches [6,7]. CNT-cellulose papers (CNTCPs) are very good host for activated materials, which have a porous structure, easy formability, flexibility, and excellent physical and chemical properties. The porous CNTCP has excellent flexibility and conductivity. It has a broad application prospect for LIB applications including lithium-sulfur battery [1-15], Nano-SnO 2 anode , silicone anode [44-56], Li/CFx battery [57][58][59][60][61][62][63], and supercapacitors [64][65][66][67][68][69][70][71][72][73][74][75][76][77][78][79][80]. In this paper, we report the porous CNTCP applications as current collector and electrode for lithium ion battery and supercapacitor, respectively. Moreover, the CNTs used in this study are whisker multiwalled carbon nanotubes.The fabrication process of the papers is simple and scalable, similar to those technology widely used for paper making in industry. The porous CNTCP with interconnected channel ...

“…The cellulose acts as an ioninduced aggregation in the aerogel. [14] Moreover, most cellulose-derived carbon materials, such as the cellulose-derived carbon nanofibril networks, [15] the cellulose-based carbon aerogels [16] and the cellulose nanofibers based carbon aerogels, [17] have a good graphitized texture, high porosity and adjustable structure, which are greatly conductive to the charge transfer and the ion diffusion. [15] The ionic liquid composed of anions and organic cations is a green and efficient solvent.…”

As an abundant biomaterial, lignin is often used as a low-end material, because it has an inferior formability at normal temperature and a poor solubility in most solvents. In this study, an innovative lignin/cellulose carbon aerogel with a 3D hierarchical network structure composed of nanochains connecting nanospheres is successfully synthesized by dissolving cellulose and lignin in 1-butyl-3-methylimidazolium chloride, regenerating in deionized water, freeze-drying, and carbonizing. Cellulose, as the adhesive connects lignin by hydrogen bonds, increases the specific surface area and improves the graphitization degree. Consequently, the sample with 10 wt % cellulose (C-10) has a high specific capacitance (166 F g À 1 at 0.1 A g À 1 ), low impedance (τ = 5.56 ms), and excellent capacitance retention (98.6 % after 1000 cycles). The C-10-based flexible supercapacitor exhibits a stable output capability (� 99 %) at different bending angles, long cycle life (� 1000 cycles), and high energy density (102 Wh kg À 1 at 175 W kg À 1 ).[a] T.

“…Nevertheless, cellulose hydrogels could also have interesting applications as aqueous gel polymer electrolytes, for example in aqueous electric double-layer capacitors and dye-sensitized solar cells [20,26]. Cellulose has also been considered as possible starting materials for proton exchange membranes (PEMs) in PEM fuel cells (FCs) [27], as well as electrode components in some types of FCs and supercapacitors [26,27,28,29,30]. Very recently, electricity and H 2 generation from hemicellulose by sequential fermentation and microbial fuel/electrolysis cells has been reported [31].…”

Synthesis and Characterization of Cellulose-Based Hydrogels to Be Used as Gel Electrolytes

et al. 2015

Cellulose-based hydrogels, obtained by tuned, low-cost synthetic routes, are proposed as convenient gel electrolyte membranes. Hydrogels have been prepared from different types of cellulose by optimized solubilization and crosslinking steps. The obtained gel membranes have been characterized by infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, and mechanical tests in order to investigate the crosslinking occurrence and modifications of cellulose resulting from the synthetic process, morphology of the hydrogels, their thermal stability, and viscoelastic-extensional properties, respectively. Hydrogels liquid uptake capability and ionic conductivity, derived from absorption of aqueous electrolytic solutions, have been evaluated, to assess the successful applicability of the proposed membranes as gel electrolytes for electrochemical devices. To this purpose, the redox behavior of electroactive species entrapped into the hydrogels has been investigated by cyclic voltammetry tests, revealing very high reversibility and ion diffusivity.
