- the invention also relates to a method for producing a tank arranged to receive a component capable of releasing heat during its operation, in particular this component being an electrochemical energy storage module, the method comprising the steps following:
- the method comprises the following step:
- the double plate structure is heated in an oven.
- the double plate structure is folded in contact with a mandrel, in particular of cylindrical shape, to form the rounded corner(s).
- the double plate structure is wrapped around a mandrel and stretched at the same time in order to limit crushing of the channels.
