Purpose and goal
We propose to 3D print an entire Lithium-Ion micro battery, i.e. electrodes, electrolyte, current collector and encapsulation. An extrusion-based direct-writing process can be used to print the electrodes and the solid electrolyte. For current collectors and encapsulation, either direct writing or filament based materials will be investigated. We plan to use graphene oxide-based inks for printing the electrodes, a gel polymer for printing the solid electrolyte, a conductive material for the connectors, and silicone/thermoplastic polyurethane material for encapsulation.
Expected results and effects
3D Printing of battery has a clear potential in the area of micro devices and sensors applications in various sectors like transport (aircraft and automotive), biomedical devices, flexible lcd screens and solar cells. Once the concept of the fully printed micro battery is verified, the plan is to attract the industry’s interest for further development. A consortium of industry, universities and research institutes will be formed to explore various funding options. The development activities will focus on the cost effectiveness and performance of the printed batteries.
Planned approach and implementation
The project work is divided into three work packages (WP) to address the most important aspects of “all printed” power sources. WP1: Battery component Ink preparation & Rheology characterization WP2: Process set up and battery manufacturing WP3: Electrochemical testing and characterization The project duration is for 12 months. WP 1 & 2 will run simultaneously. WP 3 will start after the manufacturing of first prototype battery (Milestone set for month 8). Feedback from WP3 during months 9-11 will be used to refine materials, process parameters and iterate over various battery designs.
