Title:
MANUFACTURING METHOD OF POSITIVE ACTIVE MATERIAL FOR NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2008159300
Kind Code:
A
Abstract:
To provide a method for manufacturing a positive active material for a nonaqueous secondary battery having high capacity at least similar to the conventional active material simply even in a device and operation.
In the manufacturing method of the positive active material for the nonaqueous secondary battery by baking a mixture of metal element compounds, the mixture obtained by conducting mixing, drying, and crushing at the same time with crushing media and a vibration dryer, and preferably, mixing, drying and crushing are conducted in a state in which no places condensing moisture are present in the vibration dryer.
