Boom of new energy electric vehicle drives engineers to improves thermal management of battery pack. Cell to pack structural battery pack is one of solutions to optimize thermal management and increase energy density, extending range of mileage, thermally conductive adhesive is ideal for “cell to pack” battery pack. Compared with regular thermal gap pad and two-component thermal gap filler, thermally conductive adhesive provides strong bonding strength besides thermal performance and gap filling. At present, there is no technical standard for theramlly conductive adhesive which will be applied to EV battery pack. In such a situation, GLPOLY developed XK-D series of thermally conductive adhesive for “cell to pack” battery pack. GLPOLY XK-D series is an epoxy based, high performance, electrically isolating, high bonding strength structural adhesive. GLPOLY XK-D series thermally conductive epoxy adhesive cures at room temperature also can be accelerated with extra heat. This kind of materials provides high bonding strength for application where structural bonding is required, eliminating the need for fasteners and maintaining structural bond in severe environments.

It becomes a trend that thermally coonductive adhesives will be applied in electrical vehicle battery pack instead of encapsulant. What kind of material is thermally conductive adhesive? GLPOLY thermally conductive adhesive XK-D20 is two-component, epoxy based, dispensable adhesive. It has a thermal conductivity of 2.0W/mK. XK-D20 thermally conductive adhesive (thermal gap filler) has a high bond strength with room temperature cure. The strong bonding eliminates the need for mechanical fasteners and maintains structual bond in severe environments. It is supplied in two-component format, mix ratio 1:1 by volume and suitable for automated dispensing equipments, improving productivity and saving cost. Bergquist Liqui-Bond EA1085 is the most famous one, let’s check it out what material it contains and how about the thermal performance is. Bergquist Liqui-Bond EA1085 is a epoxy based, dispensable adhesive, it has a thermal conductivity of 1.8W/mK, it provides a lower performance than GLPOLY XK-D20 thermally conductive adhesive. Absolutely, GLPOLY XK-D20 can substitute for Bergquist Liqui-Bond EA1805. GLPOLY XK-D20 will deflect easily under very low compressive forces resulting in thin bondliness and very low stress applied on fragile components. It is recommended for filling irregular surface. XK-D20 thermally conductive adhesive provides high thermal performance, strong bonding and vibration dampening, it is ideal for thermal management of electrical vehicle battery pack.

How should we select Al or Al-plastic film in “cell to pack” structure of blade-like battery and “811”battery? GLPOLY thermally conductive structrual adhesive is overturning the market. With the boom of “cell to pack” structure of battery pack, a dramatic increase in energy density raised. But battery pack thermal management is lagging behind. In such a situation, GLPOLY has launched XK-D series of thermally conductive structural adhesive to solve thermally conductive and bonding strength problems of “cell to pack” battery pack. Here is the analysis for your reference. 1) According to our DFEAM , when the Al-plastic film used, we found that the bonding strength of Al-plastic film is less than 1.0MPa, “Al-plastic film” structural battery pack will be destroyed, even cause explosion easily in disaster impact. Al-Al is the best for reliability, security and enviromental adaptability, even the cost. 2) At present, there is a dozen varieties of three kind of categories, including”Al-Epoxy film”, “Al-PVC film” and “Al-Acrylic film” at least, even more fake products. 3) Cost: “Al-Al” structure is the most economical way at present. 4) More seriously, many engineers deemed that thermally conductive epoxy adhesive is brittle and raised resistance to our XK-D series of thermally conductive epoxy adhesive. Actually, our XK-D products provide a better elasticity than nylon. 5) Some engineers prefered Polyurethane based thermally conductive adhesive to Epoxy based thermally conductive structural adhesive. If the “Al-Plastic film” was not abandoned, the polyurethane could not bring you any benefits too. This will offer market space to fake products. GLPOLY two-component thermally conductive structural adhesive has been applied to celle to pack battery pack in several car makers and battery pack manufacturers. GLPOLY has partnered with dJI, Huawei Marine, DT Mobile, Han’s Laser etc top-class brands, providing high performance thermal interface materials for them to protect their brand reputation for performance and reliability.
