An accumulator may include a housing with at least two mutually opposite housing walls, accumulator cells arranged between the housing walls and following one another in a stacking direction, and at least one intermediate piece arranged in the housing between at least one of the accumulator cells and one of the housing walls and that retains the accumulator cells in the housing. At least one intermediate piece may be configured as a mutable intermediate piece in such a way that the mutable intermediate piece may be changeable between a first state having a first thickness extending in a spacing direction between the associated housing wall and the associated at least one of the accumulator cells, and a second state having a second thickness extending in the spacing direction, wherein the second thickness may be greater than the first thickness. In the state in which the mutable intermediate piece and the accumulator cells may be arranged in the housing, the mutable intermediate piece may be changed into the second state.
