20090148764METHOD FOR HIGH VOLUME MANUFACTURING OF THIN FILM BATTERIES - 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.06-11-2009
20090288943THIN FILM BATTERIES AND METHODS FOR MANUFACTURING SAME - A method of fabricating a layer of a thin film battery comprises providing a sputtering target and depositing the layer on a substrate using a physical vapor deposition process enhanced by a combination of plasma processes. The deposition process may include: (1) generation of a plasma between the target and the substrate; (2) sputtering the target; (3) supplying microwave energy to the plasma; and (4) applying radio frequency power to the substrate. A sputtering target for a thin film battery cathode layer has an average composition of LiM11-26-2009
20090304912METHOD FOR MANUFACTURING ELECTROCHROMIC DEVICES - This invention contemplates the use of laser patterning/scribing in electrochromic device manufacture, anywhere during the manufacturing process as deemed appropriate and necessary for electrochromic device manufacturability, yield and functionality, while integrating the laser scribing so as to ensure the active layers of the device are protected to ensure long term reliability. It is envisaged that the laser is used to pattern the component layers of electrochromic devices by directly removing (ablating) the material of the component layers. The invention includes a manufacturing method for an electrochromic device comprising one or more focused laser patterning steps. To minimize redeposition of laser ablated material and particulate formation on device surfaces a number of approaches may be used: (1) ablated material generated by the focused laser patterning may be removed by vacuum suction and/or application of an inert gas jet in the vicinity of the laser ablation of device material; (2) spatial separation of the edges of layers and patterning of lower layers prior to deposition of upper layers; and (3) the laser patterning step may be performed by a laser beam focused directly on the deposited layers from above, by a laser beam directed through the transparent substrate, or by a combination of both.12-10-2009
