This text is auto transcribed and auto-summarized by AI: Screen printing is becoming increasingly finer and smaller, and it is expected that within a few years we will be reaching 20 micrometer line widths and maybe even lower. The wafer per hour rate for the back end processes is also rising, and it is projected to rise to >10,000 wafers per hour by the next years The state of the art for screen printing on solar cells is 19 micrometers and above, with an aspect ratio of 1818 micrometers. This is a relatively easy application, because the pictures are very wide and interrupted lines can be tolerated.
Micro-led displays are very hot display topic, and one of the key uniques of this display technology is that you can create bezel free displays. This means that you can create a larger display by putting together many kind of smaller tiles and building up the big display.
One way to create wraparound edge electrodes is to drill via into the glass, fill the field and feel the field through glass fires. But this is really not elegant, so a more interesting approach would be to create this so called wraparound edge electrodes.
Screen printing can produce very fine lines, but as micro led dyes shrink in size, the bond sizes and metallization lines will also get smaller, which means that if screen printing is to stay competitive in this technology, it also has to produce ever finer lines. Applied Materials showed how they can print screen printed lines as fine as 15 micrometers, b...

Electrolytes hold the key for enabling various battery chemistries including solid state batteries. Currently, the electrolyte based on using LiPF6 as salt and ethylene carbonate/dimethyl carbonate as solvents have been very successful for applications under normal conditions. However, extreme conditions can arise from using batteries during very cold weather or increasing the charge voltage limit to increase overall energy density. Conventional electrolytes fail under these conditions because they cannot support effective lithium ion transport across the electrolyte and the interphase. @Enyaun Hu et at @Brookhaven National Laboratory has been working on developing novel electrolytes for extreme conditions by engineering the solvent and the electrolyte additives. In the following slides we give us a sneak peak view of the latest two insights obtained by taking advantage of the local synchrotron facility, which enables to characterize the electrolyte and the interphase with techniques that are beyond the reach of lab-based tools. Much more will be presented at TechBlick’s event on (a) Frontier Battery Materials and (b) Solid-State Battery Materials on 15-16 Feb 2023 online. https://www.techblick.com/event/batterymaterials In particular, it will be shown how ✔️ isoxazole-based electrolytes in Li | SPAN batteries can improve performance at ultra low temperatures (e.g., -30C) despite having lower bulk conductivity. Here, the origins are studies using XAS and XRF imaging, attribu...

In the video presentation below, TechBlick reviews several industrial applications of Printed Electronics. It is often the case that when printed electronics succeed, it is no longer called printed electronics! As such, many consider printed electronics forever a technology of the future without recognising the enormous successes it already enjoys. To this end, we have prepared a presentation, giving an overview of a diverse array of industrialized applications based on printed electronics. This existing and emerging applications that this TechBlick presentation covers include: ✅ Printed metalization of Si PVs (PERC, Topcon, and HJT PVs) ✅ Organic and Perovskite Photovoltaics ✅ QD-OLED Displays ✅ MicroLED Color Conversation ✅ MLCCs ✅ PCB Industry (solder printing, solder & legend printing) ✅ Automotive industry (from occupancy sensors to seat heaters to 3D touch surfaces) ✅ Medical and Biosensors (from glucose test strips to multilayer precision biosensors) ✅ HMIs ✅ 2.5D and 3D Electronics ✅ Intelligent packaging ✅ Semiconductor packaging ✅ and many more Scroll down to watch the full video and download the slides.

Thin-Film Solid-State Batteries - sometimes known as “Microbatteries” - can power wireless sensors, smart cards, active RFID tags, and microelectronics as SMT components. This is an active area of research with tremendous potential for future advancements. Group for Thin-Film Batteries @Empa led by @Yaroslav Romanyuk (https://www.empa.ch/web/s207/thin-film-batteries) is exploiting the 2D thin-film geometry to discover novel materials and investigate interface phenomena, paving the way for the next generation of solid-state batteries. Here, we offer a sneak peek, including a unique patent-pending monolithic multi-cell solid-state battery manufactured using all-dry vacuum processes offering rapid charge/discharge. Here the calculated performance of a monolithic multi-cell battery is shown on a Ragone plot, showing it can potentially outperform Li-ion batteries in terms of power density (W/Kg), offering a rapid charge in less than a minute. The latest results and developments will be presented at TechBlick’s event on (1) Solid-State Batteries and (b) Solid-State Battery Materials on 15-16 Feb 2023 online. https://www.techblick.com/event/batterymaterials. ✔️ Slide 1: Fabrication line for all-vacuum thin-film solid-state batteries. Manufacturing methods include various physical vapor deposition (PVD) processes, such as magnetron sputtering and thermal evaporation.

Solid-State-Batteries with metal (e.g., Li) anodes have the potential to dramatically increase the energy density of batteries beyond what standard Li-ion batteries can do. In electric vehicles, this could boost driving range to 700-800Km! A well-known technology challenge is excessive dendrite growth, shortening cell lifespan and perhaps even compromising safety by causing short circuits. In this post, @Albert Schneiders from @CNM Technologies offers a potential solution based on R2R-manufactured 2-dimensional insulating carbon nano-membranes. All the details will be presented at TechBlick’s event on (a) Frontier Battery Materials and (b) Solid-State Battery Materials on 15-16 Feb 2023 online. https://www.techblick.com/event/solidstatebatteries ✔️ Helium ion microscopy image of freestanding CNMs over a copper grid. These materials are insulating and are shown to conduct Li ions. They have potential to be manufactured at scale using R2R processes ✔️ Measurement data showing that the insertion of a 2D carbon nanomembrane can double the lifetime of a symmetric Li coin cell!! This technology could be applied to: ▶️ Liquid electrolyte/quasi solid state electrolytes as a functional layer over a conventional separator facing metal anode ▶️ Solid state electrolytes over ceramic solid state electrolytes to improve the ionic conductivity at the interface ▶️ Artificial SEI as an artificial solid electrolyte interface on Cu electrode enabling anodeless metal batteries These result...
