Printable and Flexible Solid-State Batteries

Abstract

The advancement of printable and flexible batteries has widely broadened the applications and potential of these devices beyond what was achievable by conventional batteries. Advanced printing technologies have produced highly precise and powerful printable batteries and have enabled them to be made in a variety of shapes and sizes. Additionally, the development of materials used in printing ink has also made a significant impact on the performance and shape of these batteries. The most representative and significant innovation of these materials is the emergence of solid electrolytes. Notably, solid electrolytes are safer than their liquid electrolyte counterparts and can remove rigid inactive substances, such as separators, to reduce battery size and make the devices more flexible. This chapter discusses the materials used in printable and flexible solid-state batteries, the designs and techniques used to assemble these batteries, and current state-of-the-art progress and limitations of printable and flexible solid-state batteries.
