“…The equivalent series resistance ( Rs ) value of the RGO‐Cell paper, corresponding to the intercept of semicircle with the real axis at high‐frequency region, is 19.3 Ω. This value is related to the intrinsic resistance of RGO‐Cell paper, total resistances of the ionic resistance of electrolyte, and contact resistance at the interface between active material and current collector 57,58 . The charge‐transfer resistance ( Rct ) is 13.1 Ω, stemmed from arc diameter of high frequency region on real axis 58,59 .…”

Herein, a fully paper‐based all‐solid‐state supercapacitor with functionalized cellulose paper as electrodes, carboxymethyl cellulose gel as solid electrolyte and cellulose paper as separator was fabricated. The electrode was fabricated by a conventional papermaking process with silver‐modified fibers and graphene oxide (GO)‐modified fibers followed by reduction of GO. The Ag‐modified fibers and GO‐modified fibers were obtained by in situ growth of Ag nanoparticles and self‐assembly of GO sheets on cellulose fibers, respectively. Ag‐modified fibers act as a flexible current collector with rich three‐dimensional interconnected electron transport pathways to make the reduced GO‐modified fibers as electrode materials to achieve high conductivity (1.93 Ω sq−1) and high‐rate capability. Simple drying can reduce 40% weight of the supercapacitor to facilitate transportation and storage, and its capacitance efficiency can be recovered by wetting when needed. This work opens up a new way of developing cheap, green and high performance full‐paper flexible electronics by conventional papermaking process.

“…Additionally, MXenes hold high specific capacitance along with very good chemical and mechanical stability [204][205][206]. Therefore, taking the advantage of both kind of materials, Lu et al [207] fabricated Ni 2 Co-LDH and Al-Ti 3 C 2 MXene composite, i.e., Ni 2 Co-LDH@ Al-Ti 3 C 2 MXene to fabricate a supercapattery device, wherein graphene hydrogel was implemented as a negative electrode material. The combined merits of LDH, MXene and graphene made the device to achieve a higher energy density of 68 Wh kg −1 with maximum power density of 20.3 kW kg −1 .…”

“…Notably, its energy storage process relies on the fast redox reactions between the Ti 3 C 2 T x flakes and the intercalated cations. [ 29,30 ] However, like other 2D materials, Ti 3 C 2 T x is prone to restacking during fabrication using vacuum‐assisted filtration and spin or spray coating. [ 31–34 ] The restacked structure limits the ion transport in electrode materials, especially for the systems with mass loading close to or exceeding the areal density of ≈10 mg cm −2 , typical for large SCs, and thickness over tens of micrometers.…”

Although 2D Ti3C2Tx is a good candidate for supercapacitors, the restacking of nanosheets hinders the ion transport significantly at high scan rates, especially under practical mass loading (>10 mg cm−2) and thickness (tens of microns). Here, Ti3C2Tx‐NbN hybrid film is designed by self‐assembling Ti3C2Tx with 2D arrays of NbN nanocrystals. Working as an interlayer spacer of Ti3C2Tx, NbN facilitates the ion penetration through its 2D porous structure; even at extremely high scan rates. The hybrid film shows a thickness‐independent rate performance (almost the same rate capabilities from 2 to 20 000 mV s−1) for 3 and 50 µm thick electrodes. Even a 109 µm thick Ti3C2Tx‐NbN electrode shows a better rate performance than 25 µm thick pure Ti3C2Tx electrodes. This method may pave a way to controlling ion transport in electrodes composed of 2D conductive materials, which have potential applications in high‐rate energy storage and beyond.
