Abstract

A battery-module (100) is provided which comprises a first battery-cell and a second battery-cell (101), and a heat-spreader (103) for passively dissipating heat from the first to the second battery-cell (101). The heat-spreader (103) has a first section (105) and a second section (106). The first section (105) comprises a first volume (107) and a first contact-portion (201), wherein the first contact-portion (201) restricts the first volume (105) in a direction towards the first battery-cell (101) and is in thermally conductive physical contact with the first battery-cell (101) such that the first battery-cell (101) and the heat-spreader (103) can exchange heat at the first section (105). The second section (106) comprises a second volume (108) and a second contact-portion (202), wherein the second contact-portion (202) restricts the second volume (108) in a direction towards the second battery-cell (101) and is in thermally conductive physical contact with the second battery-cell (101) such that the second battery-cell (101) and the heat-spreader (103) can exchange heat at the second section (106). The heat-spreader (103) has a cooling-medium (109, 111; 431, 433) for 2-phase cooling of the first and second battery-cells (101). The first and the second section (105, 106) communicate with each other such that a transition from the first to the second aggregate-state of the cooling-medium (109, 111; 431, 433) causes a transport of cooling-medium (109, 111; 431, 433) from the first volume to the second volume (107, 108).
