Abstract
This disclosure relates to methods and apparatus for enhanced dielectric properties for electrolytic capacitors to store energy in an implantable medical device. One aspect of the present subject matter includes a method for manufacturing a capacitor adapted to be disposed in an implantable device housing. An embodiment of the method includes providing a dielectric comprising aluminum oxide and doping the aluminum oxide with an oxide having a dielectric constant greater than aluminum oxide. Doping the aluminum oxide includes using sol-gel based chemistry, electrodeposition or atomic layer deposition (ALD) in various embodiments.
