Claim 1:
2. A method of producing the layered double hydroxide of claim 1, the method comprising:
dissolving salts of Ni, Fe, V, and Co in an aqueous medium at respective predetermined molar ratios to prepare a solution;
adding acetylacetone during the preparation of the solution or after the preparation;
adding propylene oxide to the solution having added thereto acetylacetone;
leaving the solution having added thereto propylene oxide to stand for a predetermined period of time to form a gel containing a composite of Ni, Fe, V, and Co; and
leaving the gel to stand for a predetermined period of time to deflocculate the gel, to thereby form a sol containing fine particles of the layered double hydroxide represented by the formula (I).
