Abstract

A secondary battery includes: an electrode assembly including a positive electrode plate and a negative electrode plate; an exterior housing that has an opening and houses the electrode assembly; and a sealing plate (2) that seals the opening. The exterior housing and the sealing plate (2) form a battery case. A deformable member (19) that deforms when the pressure inside the battery case reaches a prescribed value or higher and a gas release valve (18) that breaks when the pressure inside the battery case reaches a prescribed value or higher to release gas inside the battery case to the outside of the battery case are provided in the sealing plate (2). A metallic reinforcing member (30) is connected to the inner surface of the sealing plate (2).

Abstract

A battery pack includes rectangular secondary batteries arranged in a state in which the secondary batteries is pressed against each other in an arrangement direction through spacers. Each secondary battery is configured such that a flat wound electrode body is housed in a battery case with a winding axis extending parallel with a long side surface of the battery case. The electrode body has a flat portion in which positive and negative electrode material mixture layers face each other with a separator interposed therebetween. The spacers include a pair of first pressing portions pressing both end portions of the long side surface, which faces the flat portion, of the battery case in a winding axis direction along a direction perpendicular to the winding axis, and a second pressing portion pressing a portion of the long side surface along the winding axis between the pair of first pressing portions.

Abstract

A rectangular secondary battery includes an electrode body, a rectangular battery case housing the electrode body, a sealing plate, a current collector extending on an end side of the sealing plate in a longitudinal direction thereof and joined, by ultrasonic welding, to an end of a positive electrode plate or a negative electrode plate, and an external terminal provided outside the sealing plate and connected to the current collector. The sealing plate has a gas discharge valve ruptured when the internal gas pressure of the battery case has reached a predetermined value or greater, and a thin portion formed between the external terminal and the gas discharge valve and formed thicker than the gas discharge valve.

Abstract

The battery module includes a plurality of batteries stacked together, and separator disposed between an adjoining two of the plurality of batteries and configured to insulate between the adjoining two of batteries. Separator includes thermal conduction suppressor and position regulator. Thermal conduction suppressor has lower thermal conductivity than position regulator and suppresses thermal conduction between the adjoining two of batteries. Position regulator has higher rigidity than thermal conduction suppressor, has dimension in stacked direction of batteries equal to or greater than dimension of thermal conduction suppressor in stacked direction, and abuts the adjoining two of batteries to regulate a position of each of the adjoining two of batteries in stacked direction.
