A lithium-ion battery in an e-mobile works perfectly within the temperature window of 20-40 ° C. As soon as the battery gets too hot or too cold, it loses a certain share of its performance and ages faster, and this consistently.
Solutions using conventional thermal management systems often reach their limits here and cannot meet the high safety requirements of e-mobility - in contrast to heat dissipation or cooling systems based on SIGRATHERM graphite materials. The high anisotropy e.g. of our flexible graphite foil leads to effective spreading of the heat across the entire foil surface and thus acts additionally as a thermal protection shield.
SGL Carbon’s SIGRATHERM high-density flexible graphite foil is made of high quality natural graphite without binders or fillers. It can be easily cut to shape, punched and even applied with an adhesive coating. Thus, it allows optimum from closure to other components or their surfaces. Excellent chemical and corrosion resistance as well as high temperature resistance and no aging behavior are additional advantages of this our sophisticated heat dissipation product.
SIGRATHERM products made of flexible graphite are designed to meet the old and new challenges of temperature management.
We use our experience we have made in the sealing business to develop products suited to the demands of tomorrow – in particular in the field of intelligent thermal management to increase battery lifetime and prevent them from aging and loosing capacity.
