COMPOSITES AND ELECTRODES FOR ELECTROCHEMICAL DEVICES AND PROCESSES FOR PRODUCING THE SAME

摘要

The present invention is directed to a composite including a substrate and a film deposited on a surface of the substrate, and processes for producing the composites. The deposited film includes at least one metal oxide having the formula: MxOy, wherein M is a first, second, or third row transition metal, x is a positive integer from 1 to 7. The film is ferromagnetic, ferrimagnetic, or both ferromagnetic and ferrimagnetic at temperatures greater than O°C and has a zero field magnetization of 0.001 emu/g or greater at a temperature of 26.85°C (300 K). Composites of the present invention may be used, for example, as electrodes in electrochemical devices
