Abstract
Concepts and methods are provided to reduce the cost and complexity of thin film battery (TFB) high volume manufacturing by eliminating and/or minimizing the use of conventional physical (shadow) masks. Laser scribing and other alternative physical maskless patterning techniques meet certain or all of the patterning requirements. In one embodiment, a method of manufacturing thin film batteries comprises providing a substrate, depositing layers corresponding to a thin film battery structure on the substrate, the layers including, in order of deposition, a cathode, an electrolyte and an anode, wherein at least one of the deposited layers is unpatterned by a physical mask during deposition, depositing a protective coating, and scribing the layers and the protective coating. Further, the edges of the layers may be covered by an encapsulation layer. Furthermore, the layers may be deposited on two substrates and then laminated to form the thin film battery.
