A method of fabricating a battery comprises selecting a battery substrate having cleavage planes, and cutting the battery substrate with pulsed laser bursts from a pulsed laser beam to control or limit fracture along the cleavage planes. The pulsed laser beam was also found to work well on thin substrates which are sized less than 100 microns. Before or after the cutting step, a plurality of battery component films can be deposited on the battery substrate. The battery component films include at least a pair of electrodes about an electrolyte which cooperate to form a battery.

What is claimed is: 1. A method of fabricating a battery on a battery substrate, the method comprising:(a) selecting a battery substrate having cleavage planes;(b) applying a plurality of pulsed laser bursts of a pulsed laser beam to the battery substrate, the pulsed laser bursts having sufficient power and duration to cut through the battery substrate substantially without causing fractures along the cleavage planes of the battery substrate; and(c) before or after (b), depositing a plurality of battery component films on the battery substrate, the battery component films comprising at least a pair of electrodes about an electrolyte that cooperate to form a battery cell.
