Positive electrode active material for secondary battery, positive electrode for secondary battery, secondary battery and method for producing positive electrode active material for secondary battery |
摘要 |
A life of a secondary battery is extended, increase in a resistance when storing a secondary battery at an elevated temperature is prevented, and increase in a resistance during a charge-discharge cycle is prevented. A positive electrode active material comprising a lithium manganate and a lithium nickelate are used. The lithium manganate is a compound represented by the following formula (1) or the compound in which some of Mn or O sites are replaced with another element: <?in-line-formulae description="In-line Formulae" end="lead"?>Li<SUB>1+x</SUB>Mn<SUB>2-x</SUB>O<SUB>4</SUB> (1) <?in-line-formulae description="In-line Formulae" end="tail"?> (in the above-shown formula (1), 0.15<=x<=0.24).
