Temperatures that are too low reduce charging and discharging efficiency. Thermally conductive adhesives, sealants, and gap fillers are critical in EV battery thermal management and safety.
The selection of adhesives and sealants depends on the desired strengths, service considerations and to a great extent on the manufacturing requirements. A wide spectrum of adhesive systems offers the industrial designer new technology options and thermal management solutions for high-voltage batteries.
According to Billotto, these adhesive materials act as interfaces between the battery cells and the cooling plates, ensuring heat is efficiently dissipated during charging and discharging. These adhesives enhance battery longevity by helping keep the batteries within the optimal temperature range (typically 35-60°C).
These adhesives keep the cells firmly in place throughout the vehicle's lifespan. Adhesive technology plays a vital role in the assembly and performance of electric vehicle battery packs. From ensuring structural integrity to managing heat and enhancing safety, adhesives, and sealants contribute significantly to the success of EVs.
An essential contribution of adhesives to EV battery design is that they allow for greater simplicity. For example, adhesives help reduce or eliminate mechanical fasteners, reducing battery complexity. Some formulations eliminate the need for primer, reducing the materials needed in production and VOCs associated with primer use.
For this reason, thermal adhesives are used at several locations in battery modules, such as between individual cells, or between cells and cooling plates. Structural adhesives are used in EV battery packs to create bonds that can withstand various environmental conditions and mechanical loads.
Dupont's BETAMATE (5) and BETAFORCE (7) are part of a broad portfolio of adhesives for numerous EV applications. The next generation of EV batteries is witnessing the emergence of cell-to-pack designs. These designs integrate battery cells into the pack using thermal structural adhesives.
It is therefore expected that the latest round of tightening regulations on technology export for cathode, lithium processing, and lithium refining will have a significant impact on the battery supply chain globally, in particular, on joint ventures, technology licensing or technical service arrangements.
These materials are indispensable in the production of lithium-ion batteries and other components vital to renewable energy and electric vehicles. "China is still set to be the dominant player," said Tony Alderson, a senior analyst at Benchmark Mineral Intelligence.
