NEGATIVE ELECTRODE FOR LITHIUM ION SECONDARY BATTERY, LITHIUM ION SECONDARY BATTERY USING THE SAME, AND METHOD OF MANUFACTURING NEGATIVE ELECTRODE FOR LITHIUM ION SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To obtain a negative electrode for a lithium ion secondary battery for achieving high capacity and long life.

SOLUTION: The negative electrode for the lithium ion secondary battery is provided with a metallic collector, and a silicon linear body grown on the collector, with at least one end of the silicon linear body coupled in metal bonding with the collector, or in metal bonding with metal on the collector. Further, the lithium ion secondary battery uses this negative electrode. The silicon linear body is formed by a VLS method.
