Current Insight into 3D Printing in Solid‐State Lithium‐Ion Batteries: A Perspective. Issue 8 (7th June 2022) - Ponnada, Srikanth
Abstract: Compared to the state‐of‐art lithium‐ion batteries, the all‐solid‐state batteries offer improved safety along with high energy and power density. Although considerable research has been conducted, the inherent problems arising from solid electrolytes and the lack of suitable electrolytes hinder their development in practical applications. Furthermore, traditional synthesis routes have drawbacks due to limited control to fabricate the solid electrolytes with desired shape and size, impeding their maximum performance. In recent years, additive manufacturing or three‐dimensional (3D) printing techniques have played a vital role in constructing solid‐state batteries because of the rational design of functional electrode and electrolyte materials for batteries with increased performance. 3D printing in batteries may provide a new technology solution for existing challenges and limitations in emerging electronic applications. This process boosts lithium‐ion batteries by creating geometry‐optimized 3D electrodes. 3D printing offers a range of advantages compared to traditional manufacturing methods, including designing and printing more active and passive components (cathodes, anodes, and electrolytes) of batteries. 3D printing offers desired thickness, shape, precise control, topological optimization of complex structure and composition, and a safe approach for preparing stable solid electrolytes, cost‐effective and environmentally friendly. Abstract : 3D printing technology is a futuristic technology to print lithium‐ion batteries and other energy storage devices to fulfill the manufacturing demand of industries. The process is fast, accurate, and versatile. This perspective sheds light on the future of 3D battery printing technology concerning materials and process challenges with possible solutions. Additionally, the authors give their thoughts about the optimum cost‐effective Inkjet printing processes, inks, and devices with specific properties applicable to next‐generation portable and flexible solid‐state batteries.
