Inkjet Printing As A Potential Development Path Towards Modern Lithium-Ion Batteries

Abstract
Owing to high energy density, high operating voltage, long cycle life, lithium-ion batteries (LIBs) are the state-of-the-art energy storage technology for application in mobile appliances and electric vehicles. The market of LIBs is continuously expanding and in the short-to medium-term future, LIBs are expected to stay the preferred battery technology. Although LIBs are well-developed, it is anticipated that the further improvement in terms of their performance, safety and cost is possible. One of the most promising strategies for improving the electrochemical performance of next-generation LIBs is three-dimensional (3D) electrode structure. Inkjet printing (IJP), as an advantageous additive manufacturing method allows for the fast deposition of thin films or complex patterns with high precision. In this work, the possibilities and challenges of fabrication of 2D/3D composite electrodes using IJP technology are presented. Furthermore, water-based inks were successfully formulated providing significant environmental benefits over conventional processing using N-methyl pyrroli done (NMP). Printability tests were performed, highlighting the relationship between rheology and the drop generation process. 2D/3D patterns were deposited and micro structural characterisation of fabricated structures was carried out.
