Recent developments in the field of mobile application and transport have heightened the need for efficient energy storage systems. Batteries are the most widespread energy storage systems for powering portable electronic device and electric vehicles. Between them, the most used type of battery is Lithium-ion batteries. Printing technologies offer simple processing and low-cost manufacturing, this result in the potential replacement of conventional technologies. 3D printing of secondary type battery received vast interest for advancing the next generation of 3D printed energy storage devices. The thesis project is focused on the synthesis of a printable polymer-based electrolyte for Li-ion battery, with a relative study of the printing process, electrochemical, and thermal properties of the electrolyte.
