“…[46][47] Our supercapacitors are comparable to other flexible supercapacitors using PEDOT or hybrid PEDOT/Carbonbased, or PEDOT/metal-based electrode materials. [48] In addition to the supercapacitor performance, using hydrogel ink to print layer by layer without heating each layer will reduce the production time and cost, and it can extend to the large-scale manufacturing of supercapacitors using syringe pump deposition or roll-to-roll printing. The planar supercapacitor structure, which is crucial for flexible and portable electronics, is also possible to produce by 3D printing.…”

Printed electronic paper identifies its interest in flexible organic electronics and sustainable and clean energy applications because of its straightforward production method, cost‐effectiveness, and positive environmental impact. However, current limitations include restricted material thickness and the use of supporting substrate for printing. Here, 2D and 3D electronic patterned paper are fabricated from direct ink writing (DIW) nanocellulose and PEDOT:PSS‐based materials using syringe deposition and 3D printing. The conductor patterns are integrated in the bulk of the paper, while non‐conductive sections are used as support to form free‐standing paper. The strong interface between the patterns of electronic patterned paper gives mechanical stability for practical handling. The conductive paper‐based electrode has 202 S cm−1 and is capable of handling electric current up to 0.7 A, which can be used for high‐power devices. Printed supercapacitor papers show high specific energy of 4.05 Wh kg−1, specific power of 4615 W kg−1 at 0.06 A g−1, and capacitance retention above 95% after 2000 cycles. The new design structure of electronic patterned papers presents a solution for additive manufacturing of paper‐based composites for supercapacitors, wearable electronics, or sensors for smart packaging.

“…Recently, commercially available and wet-processible poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) has been reported to acquire remarkable conductivity enhancement (up to 4000 S cm –1 ) after acid treatment, which offers a great opportunity for fabricating a high-performance FSSC. − In our previous work, incorporating acid-treated PEDOT:PSS in the rGO fiber was demonstrated to efficiently enhance electrical conductivity and alleviate aggregation of rGO sheets . As such, it is expected that the electrochemical performance of the MoS 2 -based FSSC could be greatly boosted by utilizing the highly conductive acid-treated PEDOT:PSS/rGO as a fiber support for coating highly electroactive materials.…”

Improving the specific capacitance and energy density of a fiber-shaped supercapacitor (FSSC) is critical to its applications as an energy storage device for advanced smart wearable electronics. In this paper, a heterogeneous poly(3,4ethylenedioxythiophene):poly(styrenesulfonate)/reduced graphene oxide/molybdenum disulfide (PEDOT:PSS/rGO/MoS 2 ) fiber was prepared to achieve a high-performance and durable electrode for the FSSC. As indicated, pseudocapacitive MoS 2 was in situ grown on a highly conductive acid-treated PEDOT:PSS/rGO assembly with a hierarchical structure. This structural design emphasizes the wrinkled morphology and high conductivity of the PEDOT:PSS/ rGO backbone to maximize the MoS 2 deposition and accelerate its electron transfer, which fully utilizes the pseudocapacitance of MoS 2 and provides additional capacitance contribution to the obtained device. Attributed to the synergy, the prepared fiber electrode in the FSSC exhibits high volumetric/areal specific capacitance (325.8 F cm −3 /405.3 mF cm −2 at 1 A cm −3 or 1.2 mA cm −2 ) and excellent rate performance (82%, 1−10 A cm −3 ). The corresponding device shows an ultrahigh volumetric energy density of 6.9 mW h cm −3 at a high power density of 173.6 mW cm −3 and an areal energy density of 8.5 μW h cm −2 at 215.9 μW cm −2 , together with excellent cycle stability and mechanical flexibility, outperforming most of the previously reported FSSCs. Accordingly, the proposed strategy provides a great opportunity to develop a high-performance FSSC for further wearable electronics.
