Dispenser Printing of Solid Polymer-Ionic Liquid Electrolytes for Lithium Ion Cells

Microfabrication of on-chip solid state electrochemical cells has provided a robust challenge to industry for the past decade. Previous efforts include RF Sputtering, screen-printing, and laser printing. All have merit in the laboratory but have proven difficult to scale due a combination of equipment cost and proper isolation from water and oxygen. We present a promising method for printing additively all structures necessary for a working lithium polymer battery that is both small enough to fit in a compact glovebox, yet scaleable for industrial production.
