Electrochemical cell having a vanadium phosphorous alloy electrode

DWPI Title: Electrode for apparatus, e.g. battery comprises vanadium phosphorus alloy, and ionomeric barrier coupled to vanadium phosphorus alloy where ionomer of ionomeric barrier includes polymer with attached cationic functional groups
Abstract: An apparatus includes an electrochemical half-cell comprising: an electrolyte, an anode; and an ionomeric barrier positioned between the electrolyte and the anode. The anode may comprise a multi-electron vanadium phosphorous. The electrochemical half-cell is configured to oxidize the vanadium and phosphorous alloy to release electrons. A method of mitigating corrosion in an electrochemical cell includes disposing an ionomeric barrier in a path of electrolyte or ion flow to an anode and mitigating anion accumulation on the surface of the anode.
Use: An electrode for apparatus, e.g. battery (all claimed).
Advantage: Corrosion in electrochemical cell is mitigated by disposing ionomeric barrier in a path of electrolyte or ion flow to anode and anion accumulation on the surface of the anode is mitigated.
Novelty: An electrode comprises vanadium phosphorus alloy; and ionomeric barrier coupled to vanadium phosphorus alloy where ionomer of ionomeric barrier includes polymer with attached cationic functional groups and polymer base of ionomeric barrier is selected from poly(phenylene), poly(sulfone), poly(ethylene), poly(arylene ether), poly(ether ether ketone), poly(styrene), or polymers with perfluorinated backbones.
