Title:
ANODE FOR LITHIUM-ION SECONDARY BATTERY, LITHIUM-ION SECONDARY BATTERY USING IT, MANUFACTURING METHOD OF ANODE FOR LITHIUM-ION SECONDARY BATTERY, AND SLURRY USED FOR MANUFACTURING
Document Type and Number:
Japanese Patent JP2010218848
Kind Code:
A
Abstract:

To provide an anode for a lithium-ion secondary battery realizing high capacity and long life, with a small electric resistance of an electrode film, and excellent in productivity.

The anode for the lithium-ion secondary battery has a conductive auxiliary and an anode active material on a collector, with the anode active material and the collector or the conductive auxiliary combined in metallic bond. On the above collector, slurry containing the conductive auxiliary, the anode active material and metal nanoparticles is coated and sintered to obtain the anode for the lithium-ion secondary battery. Since the conductive auxiliary, the anode active material and the collector are combined in metallic bond, a silicon-system alloy having an anode film of a firm porous structure and greatly expanding in a charge and discharge process can be used for the anode active material.
