Abstract
A method of fabricating a battery comprises selecting a battery substrate having cleavage planes, and depositing on the battery substrate, one or more battery component films comprising electrode films that at least partially surround an electrolyte film. Pulsed laser beam bursts are applied to the battery component films at a sufficiently high power level to vaporize portions of the films to form shaped battery features. The pulsed laser bursts shape the films substantially without causing fractures along the cleavage planes of the battery substrate. Pulsed laser shaping can be used to replace the use of a mask in the fabrication of shaped battery components.
