Abstract
An electrochemical device includes a container, a storage element, and a structure. The container includes a container main body including a first inner surface, and a lid including a second inner surface opposed to the first inner surface. The lid is bonded to the container main body. The container contains an electrolyte. The storage element includes first and second electrode layers respectively adhered to the first and second inner surfaces and a separator provided between the first and second electrode layers to retain the electrolyte, and is sandwiched between the first and second inner surfaces. The structure is provided in at least either one of the first and second inner surfaces. The structure compresses and deforms the storage element to form, in an area of the separator sandwiched between the first and second electrode layers, a thin wall portion thinner than in a peripheral area around the area.
