ANODE ACTIVE MATERIAL FOR SECONDARY BATTERY, SECONDARY BATTERY AND THEIR MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a battery which is made of a low cost raw material and has a very high utilization ratio.

SOLUTION: The anode of the secondary battery is formed by using a paste obtained through a first dispersing process in which a conductive particle chain structural substance having an oil absorption amount as bulk density index at least 50ml/100g or more is mixed with water and the above conductive particle chain structural substance is dispersed beforehand and a second dispersing process in which a paste for forming the anode active substance is obtained after a metal oxide is added and mixed with a water dispersed paste obtained in the above first dispersing process.
