It is important to analyse the test specimen to achieve the right testing system configuration. Of relevance to us are parameters such as dimensions, energy density and type of test specimen – is it a cell, a module or a pack? Beyond that, it is crucial, whether the test specimen is in prototype construction or already in series production.

For an energy storage technology, the stored energy per unit can usually be assessed by gravimetric or volumetric energy density. The volumetric energy storage density, which is widely used for LAES, is defined as the total power output or stored exergy divided by the required volume of storage parts (i.e., liquid air tank).
