An electrochemical energy storage cell includes: a housing; and at least one cell coil accommodated in the housing. The housing is closed at at least one end face by a cover. The cover forms a part of the housing. At least one insulation element is arranged between the at least one cell coil and the housing. The at least one insulation element is made of an electrically insulating and thermally conductive material.

Electrochemical energy storage cell

The invention relates to the use of a composite material, comprising a backing layer and a liquid-absorbing layer fixed on the backing layer, the liquid-absorbing layer containing fixed superabsorbent particles, there being, on the side of the liquid-absorbing layer facing away from the backing layer, a liquid-distributing layer which is in liquid-conducting contact with the liquid-absorbing layer and absorbs and distributes, in the plane of the composite material, a liquid to be absorbed, for absorbing and distributing liquids in actively- and/or passively-cooled current-carrying systems—in particular, in actively- and/or passively-cooled energy storage systems.
