An energy storage apparatus and article of manufacture is disclosed. In one embodiment, the energy storage apparatus comprises a jelly roll, having a first and second sheet and a first and second separator member, and at least one terminal element. In another embodiment, an article of manufacture comprising forming a cylindrical housing and stamping a longitudinal indentation on an exterior surface of the cylindrical housing is disclosed. In one alternate embodiment, the longitudinal indentation is adapted to slowly fracture under pressure exerted on an interior surface of the cylindrical housing, thereby preventing catastrophic failure, such as for example an explosion.
