Document Type and Number:
Japanese Patent JP6126318
Kind Code:
B2
Abstract:
The present invention provides a manufacturing method for a positive electrode active material for an olivine-type lithium-ion secondary battery, which enables a positive electrode material having excellent battery properties to be obtained through simple means. The present invention relates to a manufacturing method for a positive electrode active material for an olivine-type lithium-ion secondary battery, wherein a mixed slurry comprising (a) a transition metal compound, (b) a phosphate compound, (c) a lithium compound, (d) water, and (e) one or two kinds of pH regulator selected from NaOH and KOH is agitated and reacted at an ambient pressure that is not greater than atmospheric pressure.
