Metal-carbon composites and methods for their production

Abstract

A method of forming a metal-carbon composite, the method comprising subjecting a precursor composition to a curing step followed by a carbonization step, the precursor composition comprising: (i) a phenolic component, (ii) a crosslinkable aldehyde component, (iii) a polymerization catalyst, and (iv) metal-containing particles, wherein said carbonization step comprises heating the precursor composition at a carbonizing temperature of at least 300° C. for sufficient time to convert the precursor composition to said metal-carbon composite. The produced metal-carbon composite, devices incorporating them, and methods of their use (e.g., in capacitive deionization and lithium ion batteries) are also described.
