“…27 Moreover, graphene inks suitable for a range of printing methods have recently been demonstrated, with electrical conductivities as high as ~2.5×10 4 S/m and excellent mechanical flexibility. [31][32][33][34][35] Following a comprehensive exploration of device geometries, we find that graphene contacts embedded between consecutive IGZO printing passes yield superlative transistor operational characteristics.…”

Recent developments in solution-processed amorphous oxide semiconductors have established indium-gallium-zinc-oxide (IGZO) as a promising candidate for printed electronics. A key challenge for this vision is the integration of IGZO thin-film transistor (TFT) channels with compatible source/drain electrodes using low-temperature, solution-phase patterning methods. Here we demonstrate the suitability of inkjet-printed graphene electrodes for this purpose. In contrast to common inkjet-printed silver-based conductive inks, graphene provides a chemically stable electrode-channel interface. Furthermore, by embedding the graphene electrode between two consecutive IGZO printing passes, high-performance IGZO TFTs are achieved with an electron mobility of ∼6 cm(2)/V·s and current on/off ratio of ∼10(5). The resulting printed devices exhibit robust stability to aging in ambient as well as excellent resilience to thermal stress, thereby offering a promising platform for future printed electronics applications.

“…It has recently become a popular technique for printing a wide variety of materials, including graphene [46], carbon nanotubes [47], quantum dots [48], DNA [49], and metal nanostructures [50]. While inkjet and screen printing are limited to resolutions of approximately 12 μm and 40 μm [27,51], respectively, transfer printing can be used to pattern features below 100 nm [52,53].…”

“…In particular, stencil printing is one of mass-printing methods, which can be realized by pressing rheologically tuned inks through a preformed stencil with a squeegee. 28 Recently, besides traditional application fields of printing technology for commodity interests, printed electronics has emerged as an (a) Schematic representation depicting the stepwise fabrication procedure for PRISS cells, wherein chemical structure of their major components and a photograph of the self-standing, flexible "PRISS" letters-shaped PRISS cell were provided. The stencil-printable electrodes were composed of electrode active materials (here, LFP (for cathode) and LTO (for anode) powders were chosen as model electrode active materials), carbon black conductive additives and SCE matrix (= ETPTA polymer/high boiling point electrolyte).…”

Printable Solid-State Lithium-Ion Batteries: A New Route toward Shape-Conformable Power Sources with Aesthetic Versatility for Flexible Electronics

Forthcoming flexible/wearable electronic devices with shape diversity and mobile usability garner a great deal of attention as an innovative technology to bring unprecedented changes in our daily lives. From the power source point of view, conventional rechargeable batteries (one representative example is a lithium-ion battery) with fixed shapes and sizes have intrinsic limitations in fulfilling design/performance requirements for the flexible/wearable electronics. Here, as a facile and efficient strategy to address this formidable challenge, we demonstrate a new class of printable solid-state batteries (referred to as "PRISS batteries"). Through simple stencil printing process (followed by ultraviolet (UV) cross-linking), solid-state composite electrolyte (SCE) layer and SCE matrix-embedded electrodes are consecutively printed on arbitrary objects of complex geometries, eventually leading to fully integrated, multilayer-structured PRISS batteries with various form factors far beyond those achievable by conventional battery technologies. Tuning rheological properties of SCE paste and electrode slurry toward thixotropic fluid characteristics, along with well-tailored core elements including UV-cured triacrylate polymer and high boiling point electrolyte, is a key-enabling technology for the realization of PRISS batteries. This process/material uniqueness allows us to remove extra processing steps (related to solvent drying and liquid-electrolyte injection) and also conventional microporous separator membranes, thereupon enabling the seamless integration of shape-conformable PRISS batteries (including letters-shaped ones) into complex-shaped objects. Electrochemical behavior of PRISS batteries is elucidated via an in-depth analysis of cell impedance, which provides a theoretical basis to enable sustainable improvement of cell performance. We envision that PRISS batteries hold great promise as a reliable and scalable platform technology to open a new concept of cell architecture and fabrication route toward flexible power sources with exceptional shape conformability and aesthetic versatility.
