1. A battery device comprising:
an outer packaging having two outer side walls;
at least first battery cell group and a second battery cell group disposed in parallel between the two outer side walls, and
the first battery cell group and the second battery cell group each comprising a plurality of laminated battery cells that have at least one orthogonal surface that is an outer surface of the plurality of laminated battery cells and orthogonal to the lamination direction;
a retaining mechanism which is disposed between the first battery cell group and the second battery cell group, and retains the first battery cell group and the second battery cell group within the outer packaging, by applying a first pressure against the first battery cell group orthogonal surface in a first direction towards a first outer side wall and applying a second pressure against the second battery cell group orthogonal surface in a second direction opposite the first direction toward the second outer side wall, the first pressure and second pressure separate the first battery cell groups and the second battery cell groups,
wherein the outer packaging is an extrusion molded article with a direction following a lamination direction of the battery cells as an extruded direction, and
the plurality of battery cells are disposed in parallel in a direction orthogonal to the extrusion direction.
