ANODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERIES, ANODE ELECTRODE FOR LITHIUM SECONDARY BATTERIES, IN-VEHICLE LITHIUM SECONDARY BATTERY USING SAID ANODE ACTIVE MATERIAL AND ANODE ELECTRODE, AND METHOD FOR MANUFACTURING AN ANODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERIES

Title:

Document Type and Number:

WIPO Patent Application WO/2010/131476

Kind Code:

A1

Abstract:

Green coke from coal and/or petroleum and calcined coke from coal and/or petroleum are blended using a weight ratio between 90:10 and 10:90, and for each 100 parts by weight of the resulting coke blend, 0.1 to 6.0 parts by weight of a phosphor compound and 0.1 to 6.0 parts by weight of a boron compound are added, with weights calculated in terms of elemental phosphor/boron equivalent. The resulting coke material is fired to produce a novel anode active material for lithium secondary batteries, said anode active material having stable charging/discharging characteristics and excellent output characteristics, initial efficiency, and capacity retention rate.
