Hybrid Superelastic Metal-Metal Sulfide Materials for Current Collector and Anode of Battery

Abstract

The present invention relates to a hybrid superelastic metal-metal sulfide materials for current collector and anode of battery, which use two phase alloy of Ti—Ni or three phase alloy of Ti—Ni—X as current collector, and produce a Ti, Ni sulfide at a surface of current collector with an inside sulfide method to allow to use as an active materials of positive electrode, and perform a role of current collector and anode of battery with one material by endowing all materials with superelastic characteristic, and it have an excellent effect providing a hybrid superelastic metal-metal sulfide materials for current collector and anode having thin plate and fine wire shape.
