Title:
NONAQUEOUS ELECTROLYTE POWER STORAGE DEVICE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2019067710
Kind Code:
A
Abstract:
To provide: a nonaqueous electrolyte power storage device which is low in electrical resistance even in a terminal stage of discharge, and which can suppress a positive electrode active material from going into a deep-discharge state even in a terminal stage of discharge; and a method for manufacturing such a nonaqueous electrolyte power storage device.SOLUTION: A nonaqueous electrolyte power storage device according to an embodiment of the present invention comprises: a positive electrode including a first lithium transition metal composite oxide (I) having α-NaFeOtype crystal structure and including, as transition metal Me, Ni, Co and Mn, of which the mole ratio (A/Me) of Group I element A to the transition metal Me is less than one; and a negative electrode of which the potential rises in a terminal end of discharge.SELECTED DRAWING: Figure 2
