Abstract
The disclosure relates to a method for clamping a lithium ion accumulator, which has a lithium ion accumulator cell stack having a top surface, a base surface opposite the top surface and a peripheral surface having four side surfaces, and at least two prismatic lithium ion accumulator cells. The lithium ion accumulator cell stack is clamped by at least one tension strap apparatus which is arranged and tensioned in the region of the peripheral surface, the ends of the tension strap meanwhile being kept free of tension. While free of tension, the ends of the tension strap are connected to each other directly or indirectly by using one or two plates, which are arranged on a side surface or two mutually opposite side surfaces of the peripheral surface. The disclosure further relates to a lithium ion accumulator and a motor vehicle having a lithium ion accumulator.
