A cathode active material for a lithium secondary battery includes a lithium metal oxide particle and a thio-based compound formed on at least portion of a surface of the lithium metal oxide particle. The thio-based compound has a double bond that contains a sulfur atom. Chemical stability of the lithium metal oxide particle may be improved and surface residues may be reduced by the thio-based compound.

A power storage device electrode includes a layered structure having an organic framework layer containing aromatic dicarboxylic acid anions and an alkali metal element layer in which alkali metal elements are coordinated to oxygen atoms contained in the carboxylic acid anion to form a framework as an electrode active material, and in the whole of the electrode active material, a conductive material and a water-soluble polymer, carboxymethyl cellulose as the water-soluble polymer is contained in a range of 1.5 mass % or more and 3.5 mass % or less. In addition, the layered structure is produced by a spray drying method, and the peak intensity ratio when the power storage device electrode is subjected to X-ray diffraction measurement satisfies a predetermined range.

Tandem carbene phosphors such as those of Formula I can act as electron acceptors in tandem to increase the energy separation between the ground and excited state, which is higher than those found in analogous monometallic complexes. These compounds should find application as luminescent materials in organic light emitting diodes (OLEDs).
