Document Type and Number:
Japanese Patent JP6696692
Kind Code:
B2
Abstract:
According to one embodiment, an electrode (1) is provided. The electrode (1) includes a current collector (1a) and an active material-containing layer (1b). The active material-containing layer (1b) is provided on the current collector (1a). The active material-containing layer (1b) includes active material particles (11) and insulator particles (12). The active material-containing layer (1b) has a first surface (1b-1) facing the current collector (1a) and a second face (1b-2) as a surface of the active material-containing layer (1b). The second face (1b-2) includes a surface of a part of the insulator particles (12). A volume ratio of the insulator particles (12) decreases from the second face (1b-2) toward the first surface (1b-1) in the active material-containing layer (1b).
