Cylindrical container for e.g. lithium-ion battery, has wall with periphery part by which container rests on plane surface, and thin zone arranged on central part of wall, where thin zone is encased by over-pressure inside container

摘要

The container (1) has a wall (2) with a periphery part (2a) by which the container rests on a plane surface (3), where the container is made of aluminum. The wall has a central part (2b) and a thin zone (2c). The thin zone is arranged on the central part of the wall. The thin zone of the wall is encased by over-pressure inside the container. An independent claim is also included for a watertight storage battery comprising a container, and positive and negative current terminals.
