Abstract

A method is provided for fabricating a transition metal hexacyanometallate (TMHCM) electrode with a water-soluble binder. The method initially forms an electrode mix slurry comprising TMHCF and a water-soluble binder. The electrode mix slurry is applied to a current collector, and then dehydrated to form an electrode. The electrode mix slurry may additionally comprise a carbon additive such as carbon black, carbon fiber, carbon nanotubes, graphite, or graphene. The electrode is typically formed with TMHCM greater than 50%, by weight, as compared to a combined weight of the TMHCM, carbon additive, and binder. Also provided are a TMHCM electrode made with a water-soluble binder and a battery having a TMHCM cathode that is made with a water-soluble binder.
