Inkjet Printed Thin Film Electrodes For Lithium-Ion Batteries, Stephen D. Lawes

Electronic Thesis and Dissertation Repository

With the miniaturization of wireless electronics, the demand for ever-smaller energy storage devices has increased. Thin film batteries can meet this need by providing higher energy densities at smaller scales than conventional lithium-ion batteries. However, the fabrication of thin films batteries by vapor deposition methods typically involves expensive equipment and high temperatures, which limits their commercial application. This thesis reports the development of an inexpensive inkjet printing method of fabricating thin film electrodes for thin film lithium-ion batteries. Inks containing various electrode materials were first developed and optimized in terms of physical properties to ensure ideal jetting conditions. Then, thin …
