Title:
LAMINATED BATTERY
Document Type and Number:
Japanese Patent JP2019197677
Kind Code:
A
Abstract:
To provide a laminated battery that can improve reliability by preventing a short circuit between a first electrode plate and a second electrode plate.SOLUTION: A laminated battery 1 includes a plurality of first electrode plates 10 each including a first electrode current collector 11 including a connection region a1 and an effective region b1, a first electrode active material layer 12 provided in the effective region b1, a plurality of second electrode plates 20 alternately stacked in the stacking direction dL with the first electrode plates 10, and an insulating tape 40 joined to the first electrode plate 10. The first electrode plate 10 has a first insulator 30 provided on the surface of the first electrode active material layer 12 on the second electrode plate 20 side. The first electrode active material layer 12 includes a connection region side edge 13 that is provided on the connection region a1 side and is exposed from the first insulator 30. The insulating tape 40 covers the connection region side edge 13 of the first electrode active material layer 12.SELECTED DRAWING: Figure 4
