N/A

THE DEVELOPMENT OF A NEW GENERATION OF CERAMIC CAPACITOR ENERGY STORAGE CELL IS PROPOSED HAVING THE UNIQUE CHARACTERISTICS OF LOW COST AND HIGH EFFICIENCY (LOW ESR). THESE LARGE CERAMIC DEVICES CURRENTLY REQUIRE PRECIOUS METAL ELECTRODES AND CONSEQUENTLY ARE TOO EXPENSIVE FOR MOST USES. THE COST REDUCTION WILL BE ACHIEVED THROUGH THE ELIMINATION OF THE USUAL PRECIOUS METAL ELECTRODES. THIS IS MADE ...
