LITHIUM PHOSPHORUS COMPLEX OXIDE-CARBON COMPOSITE, METHOD FOR PRODUCING SAME, POSITIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, AND LITHIUM SECONDARY BATTERY

WIPO Patent Application WO/2010/107039

A1

Disclosed is a lithium phosphorus complex oxide-carbon composite which has high electrode density and is capable of improving the rate characteristics of a lithium secondary battery. Specifically disclosed is a lithium phosphorus complex oxide-carbon composite which is characterized by being an aggregate of lithium phosphorus complex oxide particles represented by general formula (1), said lithium phosphorus complex oxide particles aggregating via a conductive carbon material. The lithium phosphorus complex oxide-carbon composite is also characterized in that the aggregate has an average particle diameter of 1-30 μm and a tap density of not less than 0.8 g/cm3. General formula (1): LiMPO4 (In the formula, M represents one or more metal elements selected from the group consisting of Fe, Mn, Co, Ni and V.)
