Abstract
A pulsed laser can be used to ablate the desired thin film layers at a desired location, to a desired depth, without impinging significantly upon other layers. The battery cell layer order may be optionally optimized to aid in ease of laser ablation. The laser process can isolate layers of thin film within sufficient proximity to at least one edge of the final thin film battery stack to optimize active battery area.
