    Publication number: 20230006191
    Abstract: A positive electrode (100) includes a positive electrode current collector (110), a positive electrode mixture (120), and a mixture (130). The positive electrode current collector (110) has a first surface (112). The first surface (112) of the positive electrode current collector (110) includes a first region (112a), a second region (112b), and a third region (112c). The positive electrode (100) satisfies the following expression (1). 0?L3/(L1+L3)?0.075??(1) Here, L1 is a length of the positive electrode (100) of the first region (112a) of the positive electrode (100) in one direction (first direction (X)), and L3 is a length of the third region (112c) of the positive electrode (100) in the one direction (first direction (X)).
