    Abstract: PURPOSE: Provided are an electrode for lithium secondary cell using nickel/sulfur compound as electrode active material of lithium secondary cell, and a method for producing the same. CONSTITUTION: The method for producing an electrode for lithium secondary cell comprises the steps of (i) weighing nickel/sulfur compound as an active material, carbon powder as an electric conductor, an ion conductor, and a binder, and stirring the materials in solvent to form slurry, and (ii) drying the slurry to obtain an anode. The nickel/sulfur compound is at least one of NiS, NiS2, Ni7S6, and Ni3S2. The binder is polyethylene oxide when anode for high temperature is to be produced, or polyvinylidene fluoride when anode for ambient temperature is to be produced.
