Abstract
An electrode array for use in an electrochemical device is provided. The electrode array includes at least one electrode material and at least one insulating material arranged in a spiral configuration. The electrode array is manufactured by forming a composite stack of the at least one electrode material and the at least one insulating material, such that the insulating material(s) surrounds the electrode material(s) after which the stack is rolled into a spiral roll. The spiral roll can be cut, sliced, and/or dissected in numerous ways to form the electrode array of the preferred embodiments. Optionally, the sections can be further processed by machining, polishing, etching, or the like, to produce a curvature or stepped configuration.
