Abstract: Provided is a production method of a coating composition for electrode, which is able to determine suitable conditions in a dispersion step of an electrode slurry for positive electrode for lithium ion battery, in terms of numerical values, and to enhance performances of the resulting battery. A production method of an electrode slurry for positive electrode for lithium ion secondary battery, including kneading at least a carbon material as an electroconductive material and a solvent into a dispersion, is disclosed. As for the carbon material-dispersed slurry, its alternating current impedance value immediately after the dispersion is controlled to a prescribed numerical value.

Abstract: The present invention relates to a slurry for forming a semiconductor electrode layer to obtain a dye-sensitized solar cell containing a porous layer, which is not susceptible to cracking and is capable of providing a higher conversion efficiency. The slurry for forming a semiconductor electrode layer contains two types of metal-oxide semiconductor particles having different particle sizes. When a semiconductor electrode layer is formed by coating and sintering such a slurry, cracking seldom occurs and a higher conversion efficiency is achieved when it is made into a film with a thickness of 3˜20 ?m.
