A battery container for containing battery elements includes large thickness sections formed on the outer rims of walls that compose the container and small thickness areas formed in the areas surrounded by the large thickness sections. A spacer that is formed of straight-line ribs, a combination of latticed ribs and projections, cylindrical projections or the like is disposed on the small thickness areas and the outer surface of the spacing means protruded out of the outer surfaces of the large thickness sections, thereby ensuring the mechanical strength and durability of the container and at the same time allowing cooling air to circulate efficiently along the walls of the battery envelope. This facilitates the transfer of heat produced inside of the battery to the outside.
