PURPOSE: A dispersibility analysis method of a conductive material using a metal nano particle is provided to measure the dispersibility of electrode slurry and the conductive material inside an electrode objectively, thereby controlling properties of the electrode and a cell and obtaining a proper mixing protocol. CONSTITUTION: A dispersibility analysis method of a conductive material using a metal nano particle is as follows. The conductive material is dispersed in electrode slurry(140) after joining the metal nano particle to the conductive material. The distribution of the conductive material is analyzed by irradiating incident lights to the conductive material dispersed in the electrode slurry. The conductive material is one kind or more selected from a group composed of graphite, carbon black, fluoride carbon, and titanium oxide. The metal nano particle is formed of gold or silver. The size of the metal nano particle is 10-80nm. The conductive material and the metal nano particle are joined by one selected from a group a pyrolysis method, vapor deposition, surface chemical reduction and gamma irradiation. |
