Title:

SPINEL LITHIUM MANGANATE AND METHOD FOR PRODUCING THE SAME AND APPLICATIONS THEREOF

Document Type and Number:

Japanese Patent JP2021160970

Kind Code:

A

Abstract:

To provide a spinel lithium manganate having excellent charge-discharge properties and output properties at high temperatures and a lithium secondary battery having excellent charge-discharge properties and output properties at high temperatures.SOLUTION: A spinel lithium manganate contains, in its surface, phosphate and at least one metal element of aluminum, magnesium, zinc, nickel, cobalt, iron, and calcium and is represented by chemical formula Li1+XMn2-X-YMgYO4 (in the formula, X and Y are expressed as 0.02≤X≤0.10 and 0.05≤Y≤0.30), with the phosphorus/manganese molar ratio of 0.001 or more and 0.1 or less. There are also provided a method for producing the same and applications thereof.SELECTED DRAWING: None
