TREATED ACTIVE MATERIAL, METHOD FOR TREATING THEREOF, AND PASTE CONTAINING THE TREATED ACTIVE MATERIAL

摘要

At least one organic molecular chain is strongly bonded to a surface of a ctive material. By using a treated active material in which at least one org anic molecular chain is strongly bonded to a surface of active material, it is possible to maintain a charge-discharge characteristic of a secondary bat tery or the like at a good level over a long period. A treated material 1 is obtained by chemically adsorbing organic molecular chains 5 onto a surface of active material 3. A bonding force between the active mass 3 and organic molecular chains 5 is 40-400 kJ/mol. In a case where the bonding force betwe en the active material 3 and organic molecular chains 5 is 40-400 kJ/mol, wh en the treated active material 1 is used as an electrode active material of a secondary battery or the like, the charge-discharge characteristic of the secondary battery can be maintained at a good level over a long period.
