Abstract: A method for improving the lithium cobalt oxide (LiCoO2) film (such as films in thin film batteries) morphology includes using oxygen (O2) and argon (Ar) gases during sputtering deposition of the LiCoO2 film. This may allow for the manufacturing of thicker LiCoO2 films. Such a method may also significantly reduce or eliminate cracking and obvious columnar structures within the resulting LiCoO2 film layer. Sputtering using a mixture of O2 and Ar also may produce a LiCoO2 film layer that requires lower annealing temperatures to reach good utilization and has higher lithium diffusion rates.

Abstract: The disclosed embodiments relate to a battery cell which includes a weakness for relieving pressure. This battery cell includes a jelly roll comprising layers which are wound together, including a cathode with an active coating, a separator and an anode with an active coating. The jelly roll also includes a first conductive tab coupled to the cathode and a second conductive tab coupled to the anode. The jelly roll is enclosed in a flexible pouch, wherein the first and second conductive tabs extend through seals in the pouch to provide terminals for the battery cell. This pouch includes a weakness which yields when internal pressure in the pouch exceeds a threshold to create a hole which releases the internal pressure.
