“…Nanocellulose provides a 3D porous structure incorporated with carbon nanofibers and LiFePO 4 that can maintain an excellent cycling capacity (85%) even after 1000 cycles [132]. Another recent study used nanocellulose-modified polyethylene separators in the lithium battery to improve the cycling stability of a high-energy density lithium battery [133]. The nanofiber layer is thermally stable and flexible with hydrophilic property; it was coated with polyethylene on both sides to fabricate a novel trilayer separator that significantly enhanced the cycling stability and safety of the lithium battery [133].…”

There is currently strong demand for the development of advanced energy storage devices with inexpensive, flexibility, lightweight, and eco-friendly materials. Cellulose is considered as a suitable material that has the potential to meet the requirements of the advanced energy storage devices. Specifically, nanocellulose has been shown to be an environmentally friendly material that has low density and high specific strength, Young’s modulus, and surface-to-volume ratio compared to synthetic materials. Furthermore, it can be isolated from a variety of plants through several simple and rapid methods. Cellulose-based conductive composite membranes can be assembled into supercapacitors to achieve free-standing, lightweight, and flexible energy storage devices. Therefore, they have attracted extensive research interest for the development of small-size wearable devices, implantable sensors, and smart skin. Various conductive materials can be loaded onto nanocellulose substrates to endow or enhance the electrochemical performance of supercapacitors by taking advantage of the high loading capacity of nanocellulose membranes for brittle conductive materials. Several factors can impact the electronic performance of a nanocellulose-based supercapacitor, such as the methods of loading conductive materials and the types of conductive materials, as will be discussed in this review.

“…In previous reports, we have presented a conductive paper that we refer to as “power paper” ( Figure a). The “power paper” is based on PEDOT:PSS composited with cellulose nanofibrils (CNF), and has been explored as the electrodes in symmetric pseudocapacitor devices . The CNF provides a mechanically robust nanoporous network onto which the conductive polymer self‐organizes to form a conductive cladding layer, as was shown from atomic force microscopy (AFM), grazing incidence wide‐angle x‐ray scattering (GIWAXS), and X‐ray photoelectron spectroscopy (XPS) .…”

availability of renewable energy. While batteries can store large amount of energy per unit mass/volume (energy density), supercapacitors can typically be charged and discharged at relatively higher rates and possess generally a longer lifetime. Lithium-ion batteries (LIB) have one of the highest energy densities among commercial batteries and are already used in grid-scale electrical energy storage systems. However, LIB systems are typically expensive to manufacture, and the restrictions and precautions that apply to largescale LIBs with respect to transportation and operation are rigorous, due to that battery failure may cause fires and explosions. Besides cost, safety, and lifetime, another important aspect, which is less frequently discussed, is the environmental impact of different energy storage technologies; recycling is particularly challenging for LIB technology. Battery technologies rely on a vast array of metals that are extracted through rare earth mining and bottlenecks in the supply of these materials is a challenge. This (surface) mining industry consumes large amounts of energy in itself, leaves our planet with scars and produces great amounts of waste that is utterly difficult and costly to clean. Many of these metals are also toxic and may cause many problems if leakage of the battery components occurs due to improper disposal. Finally, there are no efficient large-scale recycling procedures for many battery technologies (e.g., LIB) as of today. [1] In the search for green energy storage solutions, more and more attention has been focused on organic materials such as using conductive polymers and redox-active molecules. [2] Organic materials can be manufactured and processed at high volumes, at low temperatures, thus enabling a cost-effective production process of energy storage technologies. Many organic materials are flexible and can be dissolved in aqueous or organic solvents, which allows for high-throughput manufacturing techniques, such as using printing, coating, and lamination. Several conductive polymers, such as polythiophene, polypyrrole, polyaniline, and poly(3,4-ethylenedioxythiophene) (PEDOT), have been widely studied and explored as the electrode materials in batteries and supercapacitors. [3] PEDOT is considered to be one of the most chemically, electrochemically, and mechanically stable conductive polymers, especially when combined with the polymeric counter-ion poly(styrene sulfonate) (PSS). Also, PEDOT:PSS has a high mixed ionic and electronic conductivity, but exhibits a relatively low specific capacitance of about 30-40 F g −1 . [4] A supercapacitor made from organic and nature-based materials, such as conductive polymers (PEDOT:PSS), nanocellulose, and an the organic dye molecule (alizarin), is demonstrated. The dye molecule, which historically was extracted from the roots of the plant rubia tinctorum, is here responsible for the improvement in energy storage capacity, while the conductive polymer provides bulk charge transport within the composite electrode.

“…A large number of oxygen-containing functional groups on nanocellulose make them easier to decorate with electroactive materials and to modify the physicochemical properties [34,35,36,37,38,39]. Therefore, nanocellulose-based composite aerogel represents a versatile matrix to prepare lightweight hybrid materials [40,41,42,43,44]. Yang et al have integrated spherical manganese dioxide nanoparticles and other kinds of active nanomaterials with the cellulose nanocrystal (a type of nanocellulose) aerogels, and lightweight, highly porous, and flexible hybrid aerogels for the development of supercapacitor materials [45].…”

Bio-waste derived nanocelluloses show excellent mechanical flexibility and self-aggregated capability, which enable them to be good supporting substrates for the synthesis of electroactive materials. Herein, we present a facile route for fabricating composite aerogels consisting of carbonized nanocellulose fibers (CNF) and mixed-valent manganese oxide (MnOx), toward supercapacitor applications. Mixed solutions of nanocellulose and manganese acetate with different ratios were prepared and freeze-dried into hybrid aerogels. The hybrid aerogels were then transformed into CNF/MnOx composites by a calcination process. The CNF membranes served as porous carbon nano-reservoirs for MnOx and electrolyte. The CNF/MnOx composites also kept a 3D porous aerogel structure with hierarchical pores, which enabled stable transport of both electrolyte ions and electrons to the electrode surface, leading to low a charge-transfer impedance and good electrochemical kinetics. The CNF/MnOx-based symmetric supercapacitor showed a satisfied energy density and power density of 37.5 Wh kg−1 and 2.75 kW kg−1, respectively. All the above results demonstrate the feasibility of using sustainable nanocellulose as a nanoscale carbon substrate for the synthesis of hybrid composite electrodes toward renewable supercapacitor applications.
