Anode current collector, conductive material, and fluoride ion battery

Abstract

A main object of the present invention is to provide an anode current collector that is capable of inhibiting the reaction with liquid electrolyte. The present invention achieves the object by providing an anode current collector to be used for a fluoride ion battery; and the anode current collector being a simple substance of Fe, Mg, or Ti, or an alloy containing one or more of these metal elements.

What is claimed is: 
     
         1 . A fluoride ion battery comprising a cathode active material layer comprising a cathode active material, an anode active material layer comprising an anode active material, a liquid electrolyte layer formed between the cathode active material layer and the anode active material layer, a cathode current collector for collecting currents of the cathode active material layer and an anode current collector for collecting currents of the anode active material layer,
 wherein at least one of the cathode active material layer and the anode active material layer comprises a conductive material that is a simple substance of Fe.   
     
     
         2 . A conductive material to be used for a fluoride ion battery, the conductive material comprising a simple substance of Fe.
