“…In addition, the material has high flexibility and cycling stability (initial capacity is maintained at 92% after 10,000 cycles). There is also research [ 143 ] related to the study of a hierarchically organized Ni-V layered double hydroxide (nickel-vanadium hydrotalcite) supercapacitor electrode, which exhibited a specific capacitance of 1069 F/g at 1 A/g, and after 1500 charge-discharge cycles at 20 A/g, this parameter remained at 68%. In addition to the materials discussed above, amorphous FeOOH [ 76 ], which in combination with MnO 2 is characterized by high specific capacitance and good rate capability (350.2 F/g at 0.5 A/g and 159.5 F/g at 20 A/g), was also used for printing supercapacitor electrodes.…”

The development of scientific and technological foundations for the creation of high-performance energy storage devices is becoming increasingly important due to the rapid development of microelectronics, including flexible and wearable microelectronics. Supercapacitors are indispensable devices for the power supply of systems requiring high power, high charging-discharging rates, cyclic stability, and long service life and a wide range of operating temperatures (from −40 to 70 °C). The use of printing technologies gives an opportunity to move the production of such devices to a new level due to the possibility of the automated formation of micro-supercapacitors (including flexible, stretchable, wearable) with the required type of geometric implementation, to reduce time and labour costs for their creation, and to expand the prospects of their commercialization and widespread use. Within the framework of this review, we have focused on the consideration of the key commonly used supercapacitor electrode materials and highlighted examples of their successful printing in the process of assembling miniature energy storage devices.

“…In the three-electrode system, the working electrode was dipped ~1.0 cm into the Na 2 SO 4 electrolyte (1.0 mol/L) at room temperature. The mass-specific capacitance (C, F/g) could be counted according to the galvanostatic charge/discharge (GCD) curves based on the following equation [32,33]:…”

“…The Nyquist plots of the two electrodes in Figure 3f comprise a semicircle at a high-frequency region and a straight line at a low-frequency region. The equivalent circuit diagram can be found in the illustration of Figure 3f, wherein the parameters of R 0 , CPE, R ct , and W represent the electrolyte resistance, charge transfer resistance, constant phase angle content, and Warburg resistance, respectively [33], and the fitting results are listed in Table S2. As expected, the V@P-3 electrode delivers lower R 0 (3.01 Ω) and R ct (0.12 Ω) values in comparison with those of the VO x electrode (R 0 = 3.16 Ω, R ct = 0.48 Ω), elucidating superior electrical conductivity and faster charge transfer for the V@P-3 composite.…”

As a typical pseudocapacitor material, VOx possesses mixed valence states, making it an ideal electrode material for symmetric screen-printed supercapacitors. However, its high internal resistance and low energy density are the main hurdles to its widespread application. In this study, a two-dimensional PANI@VOx nanobelt with a core-shell architecture was constructed via a two-step route. This strategy involves the preparation of VOx using a solvothermal method, and a subsequent in situ polymerization process of the PANI. By virtue of the synergistic effect between the VOx core and the PANI shell, the optimal VOx@PANI has an enhanced conductivity of 0.7 ± 0.04 S/Ω, which can deliver a high specific capacitance of 347.5 F/g at 0.5 A/g, a decent cycling life of ~72.0%, and an outstanding Coulomb efficiency of ~100% after 5000 cycles at 5 A/g. Moreover, a flexible all-solid-state symmetric supercapacitor (VOx@PANI SSC) with an in-planar interdigitated structure was screen-printed and assembled on a nickel current collector; it yielded a remarkable areal energy density of 115.17 μWh/cm2 at an areal power density of 0.39 mW/cm2, and possessed outstanding flexibility and mechanical performance. Notably, a “Xiaomi” hygrothermograph (3.0 V) was powered easily by tandem SSCs with an operating voltage of 3.1 V. Therefore, this advanced pseudocapacitor material with core-shell architecture opens novel ideas for flexible symmetric supercapacitors in powering portable/wearable products.

“…In recent years, various classes of transition metal compounds (Ni, Co, Mn, Fe, Mo, and V), in particular, oxides [9,10], hydroxides [11,12], hydroxocarbonates [7,13], sulfides [14][15][16], phosphates [17,18], and composites based on them [19][20][21], have been considered as candidates for the role of supercapacitor electrodes with a pseudocapacitative effect. According to literature data [22][23][24], the layered hydroxides and carbonate hydroxide hydrates of nickel and cobalt are of particular interest from this point of view, since wide interplanar distance in their crystal structure can greatly facilitate the access of electrolyte ions into the inner structure of the material, increasing the number of active centers involved in the electrode.…”

The hydrothermal synthesis of a hierarchically organized nanocomposite based on nickel–cobalt carbonate hydroxide hydrate of composition M(CO3)0.5(OH)·0.11H2O (where M is Ni2+ and Co2+) and nickel–cobalt layered double hydroxides (NiCo-LDH) was studied. Using synchronous thermal analysis (TGA/DSC), it was determined that the material retained thermal stability up to 200 °C. The crystal structure of the powder and the set of functional groups in its composition were determined by X-ray diffraction analysis (XRD) and Fourier transform infrared spectroscopy (FTIR). The resulting hierarchically organized nanopowder was employed as a functional ink component for microplotter printing of an electrode film, which is an array of miniature planar structures with a diameter of about 140 μm, on the surface of a nickel-plated steel substrate. Using scanning electron microscopy (SEM), it was established that the main area of the electrode “pixels” represents a thin film of individual nanorods with periodic inclusions of larger hierarchically organized spherical formations. According to atomic force microscopy (AFM) data, the mean square roughness of the material surface was 28 nm. The electrochemical properties of the printed composite film were examined; in particular, the areal specific capacitance at different current densities was calculated, and the electrochemical kinetics of the material was studied by impedance spectroscopy. It was found that the electrode material under study exhibited relatively low Rs and Rct resistance, which indicates active ion transfer at the electrode/electrolyte interface.
