ABSTRACT

Printing technology has evolved from traditional quick writing tools to the modern
manufacturing methods for functional devices and systems. The benefits of printing-based
manufacturing include less material waste, fast-turn around prototyping due to simple
design customization and wide substrate compatibility. In this presentation, all-printed
supercapacitors, where all the components are made by printing, are introduced. Because
the device is manufactured only by printing, the complexity of manufacturing facilities can
be minimized and the resource efficiency and versatility are maximized, which are
particularly important in places where the supply of material and human resources are
limited such as rural areas, environmental monitoring of nuclear sites and space exploration
missions. We have fabricated electrical double layer capacitors and pseudocapacitors, both
with high electrochemical performance and cyclic durability and the results will be discussed
in detail.
