Embedding Metal–Organic Frameworks for the Design of Flexible Hybrid Supercapacitors by Electrospinning: Synthesis of Highly Graphitized Carbon Nanofibers Containing Metal Oxide Nanoparticles

“…The electrochemical performances of Fe 2 O 3 and/or NiO‐based asymmetric supercapacitors reported in the literature are shown in Figure 9f for comparison. Clearly, compared with the values of Fe 2 O 3 @N‐doped carbon//NiO@N‐doped carbon (14.1 Wh kg −1 at 1500 W kg −1 ), [ 49 ] reduced graphene oxide/Fe 2 O 3 /carbon nanotubes//reduced graphene oxide/Fe 2 O 3 /carbon nanotubes (35.6 Wh kg −1 at 166.7 W kg −1 ), [ 50 ] Fe 2 O 3 /graphene//Co 3 O 4 /graphene (21.6 Wh kg −1 at 750 W kg −1 ), [ 51 ] Fe 2 O 3 @PPy//MnO 2 (10.6 Wh kg −1 at 16326.4 W kg −1 ), [ 52 ] Fe 2 O 3 /MXene//MnO 2 (32.2 Wh kg −1 at 900.6 W kg −1 ), [ 53 ] MXene/Fe 2 O 3 –C–MoS 2 /MXene//MXene/Fe 2 O 3 –C–MoS 2 /MXene (10.76 Wh kg −1 at 9201 W kg −1 ), [ 54 ] and ZnO@C@NiO//graphene (16 Wh kg −1 at 2704.2 W kg −1 ), [ 55 ] FOCNF‐1//NOCNF‐1 exhibits the higher energy density at the same power density, suggesting its excellent energy storage ability.…”

Last developments in polymers for wearable energy storage devices

“…The wearable SC devices are not only presented as fiber‐shaped but also as paper and film. To way of illustration, Song et al 126 demonstrated some paper‐shaped flexible SC composed by PEDOT:PSS as polymer matrix, which provides toughness, flexibility, and structural stability, rGO, and CNT as electrically conductive nanofillers and Fe 2 O 3 to increase the electrochemical performance of the new composite. The final electrode demonstrated high specific capacitance.…”

Investigation of the supercapacitor behavior of MoS2and Fe-doped MoS2nano-flowers synthesized using the hydrothermal method

“…[10][11][12] Recently, composite and/or hybrid structures have been employed to exploit the advantages of both the mechanisms. [13][14][15] Besides diverse materials, metal chalcogenides are reported to exhibit good energy storage performance because of their noticeable specific surface area, high conductivity, and strong redox potentials with multivalent oxidation states. 16,17 Molybdenum disulfide (MoS 2 ) is a prominent member of chalcogenides.…”
