Flexible Freestanding MoO3−x–Carbon Nanotubes–Nanocellulose Paper Electrodes for Charge‐Storage Applications

“…Molybdenum oxides have previously been used in a variety of electrochemical applications such as electrode materials for lithium‐ion batteries, sodium‐ion batteries, and supercapacitors . However, molybdenum oxide‐based electrodes usually suffer from low electronic conductivities, fast capacity fading, and poor electrochemical cyclabilities .…”

“…[28,29] Molybdenumo xides have previously been used in av ariety of electrochemical applicationss uch as electrode materials for lithium-ion batteries, sodium-ion batteries, and supercapacitors. [30][31][32][33][34][35] However,m olybdenum oxide-based electrodes usually suffer from low electronic conductivities, fast capacity fading,a nd poor electrochemical cyclabilities. [36] So far,m any modifications have been described in literaturet oi mprove the performance of molybdenum oxide-based electrodes;f or example,s ome studies have shown that the use of reduced molybdenum oxides (MoO 3Àx )r ather than MoO 3 can increase the pseudocapacitance of electrodes.…”

“…The limited thickness of the active material meant that the capacities of the electrodes were relativelyl ow,a nd because the electrodes also could be cycled for only approximately 2000 cycles, it was immediatelyc lear that another electrode manufacturing approach would be required to allow this type of electrodes be used in energy-storage devices, that is, am ethod that enables the increaseo ft he active materialt hickness and stabilizes the long-term cycling. One approach to increaset he performance of these electrodes could be to mix the molybdenumt rioxide with a conductive additive such as ac arbonaceous material (e.g.,g raphene or CNTs), [32,33,41] and nanocelluloset o yield flexible and freestanding paper electrodes by using the approachr ecently employed to make conductive nanofiber networks composed of CNTsa nd nanocellulose. [23,24] The present work describes as traightforward approach for the manufacturing of porous, freestanding, and flexible electrodes composed of MoO 3Àx -CNTs-CC, in which the CC serves as ad ispersing agent and flexible substrate, whereas the CNTsa ct as ac onductive additive.…”

Ethanol reduced molybdenum trioxide for Li-ion capacitors

“…The working voltage window of ECs can be extended by using organic electrolytes. [27,28] Moreover, the electrode structure has an important effect of capacitive performance, which was not studied intensively previously. By using nanocrystalline electrodes, Dunn et al demonstrated the intercalation process in ordered mesoporous MoO 3 resulting in charge storage of 605 C/g in a 2 V voltage window in an electrolyte of 1 M LiClO 4 in propylene carbonate.…”

Electrochemical Immunosensor for Carcinoembryonic Antigen Detection Based on Mo–Mn3O4/MWCNTs/Chits Nanocomposite Modified ITO Electrode

“…[30][31][32][33] It could form composite materials combined with metal oxide, which showed a good electrical conductivity as well. [34][35][36] In order to further improve the electrical conductivity of composite electrode, carbon nanotube could be induced to the electrode material.…”
