Title:
NON-AQUEOUS ELECTROLYTE BATTERY AND BATTERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/113862
Kind Code:
A1
Abstract:
According to an embodiment of the present invention, a non-aqueous electrolyte battery is provided. This non-aqueous electrolyte battery comprises a positive electrode containing a positive electrode layer, a negative electrode containing a negative electrode layer, and a non-aqueous electrolyte. The positive electrode layer contains a manganese complex oxide represented by the general formula LiMn2-xMxO4, where x is within a range of 0.22 ≤ x ≤ 0.7, and M is at least one type of element selected from the group comprising Mg, Ti, Cr, Fe, Co, Zn, Al and Ga. The negative electrode layer contains the lithium titanate Li4Ti5O12. The pore specific surface area of a positive electrode layer 62 is equal to or greater than 2 m2/g and smaller than 5 m2/g. The ratio of the positive electrode capacity per positive electrode layer pore surface area to the negative electrode capacity per negative electrode layer pore surface area is within a range equal to or greater than 1 and less than 2.4.
