Enhanced Electrochemical Performance of Nanocellulose/PPy·CuCl2 Electrodes for All-Cellulose-Based Supercapacitors

“All-in-one” polypyrrole pillar hybridization flexible membranes on multimodal tactile sensors for wearable energy-storage devices and human–machine interfaces

“…It was superior to other RGO/CNFs and CNFs@PPy composites owing to ions diffusing into the interstices of the ordered microarrays. 41,42 On the other hand, the channels between the intercalated structure formed by the CNFs and RGO nanosheets promoted ion transport throughout the electrode, effectively avoiding ion inaccessibility between adjacent RGO nanosheets. 43 Fig.…”

Cellulose-based bionanocomposites in energy storage applications-A review

“…In another study, nanosized MnO 2 was impregnated into BNC membranes followed by the polymerization of PPy with the addition of CuCl 2 .2H 2 O, washing, and drying to obtain BNC/MnO 2 /PPy/CuCl 2 nanocomposite as an electrode for supercapacitor [ 97 ]. Wesling et al [ 98 ] produced BNC/PPy/CuCl 2 nanocomposite as an electrode for supercapacitors following a similar method without MnO 2 . In another study, Ma et al [ 99 ] produced BNC/PPy/rGO bionanocomposites by in situ polymerization and vacuum filtration.…”

A Review on Nanocellulose and Its Application in Supercapacitors

“…[98] A higher concentration of nanocellulose, however, may induce agglomeration and less polymerization efficiency on the structure, that is, the exhibiting factor for supercapacitors made of nanocellulose/conducting polymers. [99] Adding nanocellulose to either carbon materials or conducting polymers alone is not effective enough to produce supercapacitors with outstanding mechanical strength and electrochemical performance, so ternary/hybrid composites made of nanocellulose and both carbon and conducting polymers should provide better results. In hybrid composites, each component (nanocellulose, carbon materials, and conducting polymers) plays important roles; 1) carbon materials improve the conductivity by creating conductive pathways within the nanostructure, and give rise to the electric double-layer effect of supercapacitors in terms of high power density 2) conducting polymers are stable, easy to process and they can further enhance the pseudocapacitive effect (redox reaction) of supercapacitors with respect to capacitance and energy density 3) nanocellulose's hydrophilicity makes it an effective electrolyte reservoir with a highly porous structure that maximizes charge transfer rate and electrolyte ion diffusion.…”
