ELECTROPHORETICALLY DEPOSITED CATHODE CAPACITOR

摘要

An electrolytic capacitor (10) includes a metal case (12), a porous pellet anode (18) disposed within the metal case, an electrolyte (16) disposed within the metal case, and a cathode element (14) formed of an elect-rophoretically deposited metal or metal oxide powder of a uniform thickness disposed within the metal case and surrounding the anode. A method of manufacturing an electrolytic capacitor includes providing a metal case (12), electrophoretically depositing on the metal can a refractory metal oxide to form a cathode element (14), and placing a porous pellet anode (18) and an electrolyte (16) within the can such that the cathode element (14) and the anode element (18) being separated by the electrolyte (16).
