WIPO Patent Application WO/2020/184359

A1

A battery (10) includes a positive electrode (100) and a first insulation layer (322). The positive electrode (100) includes a current collector (110) and a first active material layer (122). The current collector (110) has a first surface (112) and a second surface (114). The second surface (114) is on the reverse side from the first surface (112). The first active material layer (122) is positioned on the first surface (112) of the current collector (110). The first insulation layer (322) faces the first active material layer (122) of the positive electrode (100). The first active material layer (122) includes active material particles represented by LiaNibM1-bO2 (where, 0.95≤a≤1.05, b≥0.50, and M is at least one element selected from among Co, Mn, Al, Ti, Zr, Na, Ba, and Mg). The first insulation layer (322) includes magnesium hydroxide particles. The product of the basis weight and specific surface area of the magnesium hydroxide particles is 0.7 or more times greater than the product of the basis weight and specific surface area of the active material particles.
