International Classification:

H01M 4/04

US Classification:

502101, 427 77, 4271263, 4271265, 4273722, 4273833, 4273837

Abstract:

Accordingly, in various embodiments, the present invention provides methods for making electrochemically active materials. Methods include making an electrochemically active material by reacting a platinum group metal salt in a organic solvent to yield a mixture, then heating the mixture to create a metal-organic solvent complex and an acid, followed by removing at least a portion of the acid, and yielding an electrochemically active material comprising the metal-organic solvent complex. In an exemplary embodiment, the resulting electrochemically active material may be used for coating an electrode.

C25B 9/00

US Classification:

205560, 2042861, 204242

Abstract:

A cathode assembly, a system including the cathode assembly, and method of using the assembly and system are disclosed. The cathode assembly includes high surface area material to allow efficient recovery of metal at reduced current densities at the cathode, which allows increased rates of metal recovery to be obtained, while maintaining desired properties of the electrowon metal.
