Title:
A composite particle for rechargeable lithium-ion battery cathodes, a manufacturing method for the same, the cathode for rechargeable lithium-ion batteries, and a rechargeable lithium-ion battery
Document Type and Number:
Japanese Patent JP5941437
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a composite particle for a lithium ion secondary battery negative electrode, with which a lithium ion secondary battery high in discharge capacity and furthermore having excellent initial charge/discharge efficiency and cycle characteristics can be obtained when the composite particle is used as a negative electrode material for a lithium ion secondary battery.SOLUTION: A composite particle for a lithium ion secondary battery negative electrode comprises a metal particle and/or a metal compound particle which can be alloyed with lithium, and a carbonaceous material (A). The carbonaceous material binds the metal particle and/or the metal compound particle, and a surface of a member having voids is covered with a carbonaceous material (B) and a graphite material.
