“…The areal capacity of the WO 3 coated ST electrodes reached 4.84 μAh cm −2 (32.3 mAh g −1 at 2 A g −1 based on the weight of dried WO 3 ink, 44.8 mAh cm −3 at 2.78 A cm −3 calculated based on the total volume of WO 3 /AgNWs-PEDOT) and 3.88 μAh cm −2 (25.8 mAh g −1 at 4 A g −1 , 35.9 mAh cm −3 at 5.56 A cm −3 ) at current density of 0.3 and 0.6 mA cm −2 , respectively. Such areal capacities are much higher than those previously reported pure WO 3 materials [68][69][70] and our recently reported WO 3 /PEDOT:PSS composites [50], and is also comparable to the WO 3 /PANI composites [68] and other transparent capacitor films such as graphene wrapped Ni (OH) 2 nanosheet film [71] or graphene-hollow-cubes film [72].…”

The emergence of soft energy devices provides new possibilities for various applications, it also creates significant challenges in the selection of structural design and material compatibility. Herein, we demonstrate a stretchable transmissive electrochromic energy storage device by inkjet-printing single layer of WO 3 nanoparticles on an elastomeric transparent conductor. Such hybrid electrode is highly conductive and deformable, making it an excellent candidate for the application: large optical modulation of 40%, fast switching speed (<4.5 s), high coloration efficiency (75.5 cm 2 C −1), good stability and high specific capacity (32.3 mAh g −1 and 44.8 mAh cm −3). The device consists of WO 3-based hybrid electrode and polyaniline/ carbon nanotubes composite electrode. It maintains excellent electrochromic and energy storage performance even when stretched up to 50%, and achieves a maximum areal energy density of 0.61 μWh cm −2 and power density of 0.83 mW cm −2 , which is one of the highest values in stretchable transparent energy storage devices. A device featuring stretchable transparent nanowires based electrode is illustrated as an energy indicator in which the stored energy can be monitored via reversible color variation. This high performance and multifunctional electrochromic energy storage device is a promising candidate for deformable and wearable electronics.

“…So far, very few papers have been found involving the use of nickel nanowires for TCEs. In addition to the already mentioned works, [1,36,41] the articles [46,47] are interesting in our opinion. To design TCEs, Ni(OH) 2 nanolayers are enwrapped in graphene shells to design TCEs [46] .…”

The paper demonstrates a technique for applying an oriented nickel network to a glass surface. The method is based on the chemical reduction of nickel salt. The shaping and orientation of the resulting system are carried out using a micellar template of a surfactant and a magnetic field. Submicron nickel fibres are used to impart unity to the plurality of individual‐oriented nickel nanonetworks. The result is a single conductive coating on the surface of the glass, which has a transparency in the optical range. Investigations of the structure, chemical composition, morphology and electrical conductivity of the coating were performed.

“…[46][47][48] Reported works suggest that the FoM c can be enlarged either by structural engineering or hybridizing with high-capacitance pseudocapacitive materials. [49][50][51][52][53] For example, Wang's group has proposed a NaCl-templated method to fabricate graphene with different morphologies. The as-prepared graphene displays a 3D porous structure with a large surface area and showcases a high FoM c ranging from~12.4 to 20.7 when applied in TESEs.…”

“…Through solution assembly, graphene-wrapped Ni(OH) 2 nanosheets show a high areal capacitance of 49.25 mF cm À 2 at high transparency of 72.3 % (@550 nm), corresponding to a high FoM c of 52.7 F S cm À 2 . [52] When assembled into a symmetric solid-state supercapacitor, a high energy density of 2.6 μWh cm À 2 at the transparency of 51 % is obtained. However, as revealed by Coleman's group, graphene-based TESEs would encounter percolation problems.…”

Transparent energy-storage devices have aroused interest because of the ever-increasing demands of transparent electronics. Transparent energy-storage electrodes (TESEs) are indispensable for emerging cutting-edge products and have thus attracted remarkable attention in the past decade. This minireview begins by introducing the basic evaluation metrics for TESEs. Then, recent progress of various types of TESEs such as carbonaceous materials, polymers, MXenes, and other conductive substrates-based TESEs is outlined. In order to provide some inspiration and guidelines, we focus on summarizing the presently proposed strategies towards high-performance TESEs together with the applications of transparent supercapacitors. At the end of this minireview, we discuss the outlook and perspectives towards the development of transparent energy-storage devices.
