  • the invention relates to a heat dissipation element and its use for temperature control of a Li-ion battery in automobiles, trucks or pedelecs.
  • the object of the present invention is therefore to provide heating elements for Li-ion batteries, which can stabilize the temperature of the Li-ion battery to a predetermined temperature and with which the above-mentioned disadvantages of the prior art are overcome.
  • the object is achieved by the use of at least one heat dissipation element for tempering a Li-ion battery in the automobile, truck or pedelec comprising graphite and microencapsulated phase change material (PCM).
  • at least one heat dissipation element for tempering a Li-ion battery in the automobile, truck or pedelec comprising graphite and microencapsulated phase change material (PCM).
  • the heat dissipation elements are arranged in the Li-ion battery between the so-called pouch cells, so that depending on the structure of the Li-ion battery one or more heat dissipation elements are used.
  • the graphite is selected from the group consisting of natural graphite, synthetic graphite, expanded graphite or mixtures thereof.
  • graphite such as natural graphite is usually mixed with an intercalate such as nitric acid or sulfuric acid and heat-treated at an elevated temperature of, for example, 600 ° C to 1200 ° C. (DE10003927A1)
  • Expanded graphite represents a graphite that is expanded by a factor of 80 or more, for example, compared to natural graphite in the plane perpendicular to the hexagonal carbon layers. Due to the expansion, expanded graphite is characterized by excellent formability and good intermeshability. Expanded graphite may be used in sheet form, preferably using a film having a density of 0.7 to 1.8 g / cm 3 . A film having this density range has thermal conductivities of 150 W / (mK) to 500 W / (mK). The thermal conductivity is determined by the Angstrom method (Angstrom's Method of Measuring Thermal Conductivity, Amy L. Lytle, Physics Department, The College of Wooster, Theses).
  • phase change material is understood as meaning a material which undergoes a phase transition when heat is supplied or discharged. This can be, for example, a transition from the solid to the liquid phase or vice versa.
  • phase transition point is reached, the temperature remains constant until the material is completely transformed.
  • latent heat The heat supplied or removed during the phase transition, which does not cause a temperature change in the material, is called latent heat.

  • the choice of PCM depends on the temperature range in use.

In addition, these temperatures are rare, so that the material held almost exclusively without function is carried. To prevent this, the temperature range between -20 ° C and 130 ° C is selected.
  • the temperature of the Li-ion battery is stabilized, for example, the temperature can be stabilized at 6 ° C during cooling at night.
  • phase transition preferably the entire phase transition
  • at least part of the phase transition (preferably the entire phase transition) of the PCM takes place in a temperature range from 20 to 0 ° C. This can be determined calorimetrically by measuring and recording the temperature in the heat sink, exposing the heat sink in a calorimeter to a defined temperature atmosphere, and continuously ramping that temperature 20K above the melting point of the PCM (highest melting point) , 1 K / min decreases, up to one
  • Phase-change microcapsulated phase-change material in this temperature range is available from Mikrotek Laboratories Inc., Dayton, Ohio 43459, and is available under the designations MPCM 6 and MPCM 18.

On many winter mornings, the PCM will then provide exactly the energy that would otherwise have to be supplied to the Li-ion battery prior to startup with active supply of heat with heating elements.
