Present and future supercapacitor carbon electrode materials for improved energy storage used in intelligent wireless sensor systems

Template-grown graphene/porous Fe2O3 nanocomposite: A high-performance anode material for pseudocapacitors

“…Currently, the superpacapacitor market is dominated by electric double layer capacitors (EDLCs) using porous carbon as both anode and cathode materials. These devices, however, suffer from low energy density that hinders their applications [4][5][6][7][8][9]. To overcome this obstacle, extensive research efforts have been devoted to explore pseudocapacitive materials, namely, transition metal (Ni, Co, Mn, Ru, etc.)…”

Dual Planar‐Helix Type Energy Storage Wires to Circumvent Universal Energy Lag Effect

“…Carbon allotropes were well known members of supercapacitor electrodes, [ 31,32 ] and PVA/H 3 PO 4 GPE is widely used due to its nontoxic nature and possible coupling of charge transport. [ 33,34 ] The GPE in the system serves as a separator, glue, electrolyte, and elastic skeleton component at once.…”

Influence of gamma irradiation exposure on the performance of supercapacitor electrodes made from oil palm empty fruit bunches

“…Their aim is to fully utilize the advantages of the electrostatic capacitance and pseudocapacitance as well as to minimize their relative disadvantages. This is done by fabricating hybrid supercapacitor using different types of the electrode configurations, namely composite, asymmetric and battery-types [107].…”
