A composition for use in an electrochemical cell is disclosed wherein the composition includes a clean metal substantially free of impurities and a layer of protective material in contact with the clean metal. Further disclosed is an electrochemical cell including a metal film comprising a clean metal substantially free of impurities. The electrochemical cell may further include an electrolyte and a layer of protective material disposed between the electrolyte and the metal film. A process for manufacturing an electrode is further disclosed including preparing a metal film comprising a clean metal substantially free of impurities and depositing a layer of protective material on to the metal film.

Electrode compositions and processes

Lithographically patterned nanowire electrodeposition (LPNE) combines attributes of photolithography with the versatility of bottom-up electrochemical synthesis. Photolithography is employed to define the position of a sacrificial nanoband electrode, preferably formed from a metal such as nickel, copper, silver, gold or the like, which is stripped using electrooxidation or a chemical etchant to advantageously recess the nanoband electrode between a substrate surface and the photoresist to form a trench defined by the substrate surface, the photoresist and the nanoband electrode. The trench acts as a 'nanoform' to form an incipient nanowire during its electrodeposition. The width of the nanowire is determined by the electrodeposition duration while its height is determined by the height of the nanoband electrode.
