An electric storage device includes: an electrode assembly including a positive electrode plate and a negative electrode plate that are insulated from each other; a pair of current collectors each of which includes a connecting portion and is connected to a corresponding one of the positive electrode plate and the negative electrode plate at the connecting portion; a case that houses the electrode assembly and the pair of current collectors, the electrode assembly being supported by the pair of current collectors in the case; and a distance retaining member that retains a distance between portions more distal than the respective connecting portions of the pair of current collectors.

Electric storage device and spacer

An energy storage device includes an electrode assembly, a case, a terminal part, and a current collector, wherein the terminal part has: an external terminal having at least a part exposed to outside of the case; a conduction member configured to make the external terminal and the current collector conductive; a decoupling mechanism configured to decouple the conduction member, or hinder a conduction state of the conduction member; and an auxiliary terminal disposed spaced from the external terminal, and having at least a part exposed to the outside of the case, the auxiliary terminal being electrically connected to the current collector.

Energy storage device

Provided are an electric storage device in which a current collector is not easily broken even when vibration is applied, and a vehicle having this electric storage device. This electric storage device includes a case having a first inner surface and a second inner surface adjacent to the first inner surface, an electrode assembly housed in the case and including a positive electrode plate and a negative electrode plate insulated from each other, an electrode terminal disposed outside the case, and a current collector housed in the case and electrically connecting the electrode assembly and the electrode terminal to each other. A distal end edge of a distal end portion of the current collector is supported on the first inner surface of the case.
