TI-NI ALLOY-NI SULFIDE ELEMENT FOR COMBINED CURRENT COLLECTOR-ELECTRODE

摘要

The present invention relates to a superelastic alloy-Ni sulfide element for a combined current collector-electrode in which Ti-Ni based alloy is used as a current collector and Ni sulfide is used as electrode material, the Ni sulfide being formed on the Ti-Ni based alloy by forming a Ni thin film on a surface of the Ti-Ni based alloy and sulfurdizing the Ti-Ni based alloy comprising the Ni thin film. Thus, a superelastic characteristic of the element is realized as well as small-size in¬ tegration of a battery is possible.
