  • Patent number: 8870974
    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.

  • Patent number: 8502494
    Abstract: A method and apparatus for charging a rechargeable battery comprises determining a safe charging voltage Vsafe that is the maximum open circuit voltage of the battery which provides a minimum battery capacity for a predetermined number of charge and discharge cycles of the battery. The battery is charged with a voltage Vhv which is higher than the Vsafe. The charging voltage is removed and open circuit voltage of the battery is measured. The charging and measuring steps are repeated when the open circuit voltage is less than Vsafe, and the charging process is terminated when the open circuit voltage is substantially equal to Vsafe.
