  • Pulsed laser cutting of thin film battery
    Patent number: 8728176
    Abstract: A battery fabrication method comprises forming at least one battery cell on a battery substrate by 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. An overlying protective multilayer coating is formed over the battery cell. A plurality of pulsed laser bursts of a pulsed laser beam is applied to the battery substrate, the pulsed laser bursts having sufficient power and duration to cut through the battery substrate and the overlying protective multilayer coating.
    Type: Grant
    Filed: January 4, 2011
    Date of Patent: May 20, 2014
    Assignee: Front Edge Technology, Inc.
    Inventors: Jianchao Li, Kai-Wei Nieh, Sandeep Makhar

  • Thin film battery substrate cutting and fabrication process
    Patent number: 7862627
    Abstract: 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.
