It is a trend that thermally conductive structural adhesive will be used in “CTP” battery pack? Not only for better heat transfer, but for simplifying module structure to increase energy density and extend service life.
GLPOLY thermally conductive structural adhesive XK-D12 is in trial production in AIWAYS Motor and Lixiang Motor, exhibiting the most excellent performance and strongest bonding strength among competitive products.
As the boom of electric vehicle, internal strucutre of power battery pack is undergoing great change, non-modularization becomes more and more popular, and it’s been applied initiately by CATL company. Then some automakers and battery manufacturers were following suit. What’s the difference between CTP battery pack and traditional module battery pack? Obviously, there is no extra housings, all the cells are bonded by thermally conductive structural adhesive, combining functions of gap filling, heat transfer and structure bond. GLPOLY thermally conductive structural adhesive is such a gap filling material that designs to improve thermal management and range of “CTP” battery pack.
What are advantages of GLPOLY thermally conductive structural adhesives?
Firstly, it has 8MPa bonding strength while competitive products only provides 5MPa, even lower, eliminating the need of mechanical fasten, simplifying structure and increasing energy density and service life.
Secondly, thermal conductivity is optional from 1.2 to 13W/mK, improving not only the bonding issue, but also heat transfer.
Thirdly, GLPOLY had carried out accelerated aging test to prove that this material provided a 25-years service life, PU based products would never achieved this.
GLPOLY is the first one to introduce automated production lines to eliminate human error, and keep consistency of products.
GLPOLY thermally conductive structural adhesive has been applied to EV battery pack in volume production with high performance and reliability. If you want to learn more about this product or have any queries, please feel free to contact GLPOLY.
