Provided is a method of forming a method of forming a titanium dioxide (TiO) array using a zinc oxide (ZnO) template. In the method, polymer nanopatterns are formed on the substrate, and monomolecular monolayers are formed between the polymer nanopatterns on the substrate. A seed layer pattern is formed between the monomolecular monolayers on the substrate, and a zinc oxide template is formed by growing zinc oxide on the seed layer.

A cathode active material for a lithium secondary cell used in a cellular phone is disclosed. The cathode active material for the lithium secondary cell and the method the same having a high capacity and a long lifetime, different from LiCoOand LiMnO, Li(Ni, Co)O, and V-system oxide that has been researched as the active material for substituting LiCoOare provided. The cathode active material for the lithium secondary cell in the next formula 1 is obtained by heating or chemically treating diadochite [Fe(PO)(SO)(OH).6HO] that is the mineral containing PO, SO, and OH.LiFeM(PO)(SO)(OH)&#x2003;&#x2003;(1) In the formula, M is at least one element selected from a radical consisting of Mg, Ti, Cr, Mn, Co, Ni, Cu, Zn, Al, and Si, with 0&#x2266;a, c&#x2266;0.5, 1&#x2266;b&#x2266;2, 0.5&#x2266;x, y, z&#x2266;1.5.
