Biowaste-derived carbon black applied to polyaniline-based high-performance supercapacitor microelectrodes: Sustainable materials for renewable energy applications

Abstract

In recent years, there has been burgeoning interest in waste management systems as the concept of sustainable development has been and still is a subject to criticism. Reduce, reuse and recycle are three basic building Biowaste-derived carbon black applied to polyaniline-based high-performance supercapacitor microelectrodes: Sustainable materials for renewable energy applications Sumita Goswami a Gowra Raghupathy Dillip b Suman Nandy a, *

Ultraflexible all-in-one supercapacitors with high capacitance and ultrastable cycle performance enabled by wood cellulose network

“…5b. 42 During the charging process, the external circuit resulted in the directional movement of electrons and produced a potential difference between the electrodes. In order to maintain the overall electrical neutrality, the anions and cations in the electrolyte moved to the anode and cathode, respectively, and thus a dense double electric layer was formed in the interface between the MWCNT and electrolyte.…”

“…During the charging process, the external circuit resulted in the directional movement of electrons and produced a potential difference between the electrodes. In order to maintain the overall electrical neutrality, the anions and cations in the electrolyte moved to the anode and cathode, respectively, and thus a dense double electric layer was formed in the interface between the MWCNT and electrolyte 40,42 . Meanwhile, a redox reaction of PANI occurred by losing or gaining electrons, and the resulting directional movement of the anions and cations in the electrolyte produced faradic pseudocapacitance 43,44 .…”

“…The superposition of these two capacitances increased the charge storage capacity of the FSC device. In the discharge process, electrons flowed from the external circuit to the anode, which made the potential difference between the anode and cathode disappear, and the anions and cations on the surface of the electrode material broke away from the attraction of their respective electrodes and migrated back to the electrolyte, thus returning to the previous state of irregular distribution [42][43][44] .…”

Geometrical and thermal influences on a bacterial cellulose based sensing element for acceleration measurements

“…The production process can be implemented in typical laboratory conditions and enables the production of very pure cellulose. BC has been proposed for manufacturing electronics and sensors [8], [9]. Recently, BC has also been proposed for the manufacture of both actuators and hybrid and conventional solutions for mechanical sensors [10], [11].…”

Touch‐Interactive Flexible Sustainable Energy Harvester and Self‐Powered Smart Card

“…In this particular, conjugated polymer like polyaniline is a low‐cost option in this row. Some recent reports have presented the huge potential of this conducting polymer in the energy research topics though it has been immensely investigated and studied in other applications such as electrochemical cells, supercapacitors, electrochromic windows, antistatic coatings, corrosion protection, electrorheological fluids, memories . The unique property of this renowned member of π‐conjugated polymer family is that its physical and chemical properties can be easily modulated through simple doping‐dedoping processes and also it can act both as donor‐acceptor system through the π–π* interaction in its backbone .…”
