Document Type and Number:
WIPO Patent Application WO/2018/110188
Kind Code:
A1
Abstract:
Provided are a lithium ion secondary battery having excellent charge/discharge cycle characteristics and a high capacity, a method for producing same, and a precursor for constituting this lithium ion secondary battery. The lithium ion secondary battery precursor according to the present invention is characterized by comprising: a negative electrode having a negative electrode mixture layer containing a Li ion-doped negative electrode active material, wherein the negative electrode active material contains at least a Si-containing material S; a positive electrode having a positive electrode mixture layer that contains a lithium-containing metal oxide (A) containing Co, Mn, Mg, and an element M1 (M1 is at least one selected from the group consisting of Al, Ti, Sr, Zr, Nb, Ag, and Ba); and a separator. The lithium ion secondary battery according to the present invention is characterized in that the secondary battery is constituted of a nonaqueous electrolyte solution and the lithium ion secondary battery precursor according to the present invention.
