Title:
リチウムイオン二次電池用負極材、および、その製造方法、ならびに、リチウムイオン二次電池
Document Type and Number:
Japanese Patent JP5330903
Kind Code:
B2
Abstract:
The invention provides a cathode material for lithium ion secondary battery which has high charge-discharge capacity and can improve the deterioration of the cathode active substance along with the charge-discharge loop, and can perform high speed charge-discharge, producing method thereof, and lithium ion secondary battery using the cathode material for lithium ion secondary battery. The inventive cathode material 10 for lithium ion secondary battery is characterized in that the cathode material 10 for lithium ion secondary battery is formed by forming a cathode active substance 2 on the cathode current collector 1, the cathode active substance 2 is formed by dispersing 1-40 at% of Sn and 3-20at% of at least one metal selected from 4A, 4A and 6A group elements in amorphous carbon.
