battery pack
New energy vehicle battery packs are developing towards high energy density, high integration and long life, which puts forward higher requirements for structural reliability, thermal management and electrical safety. MCOTI adhesives have multiple functions such as structural bonding, thermal conductive potting, sealing protection and insulation protection. They can effectively improve the overall strength and sealing performance of the battery pack, optimize heat conduction paths, alleviate thermal stress, and ensure the safe and stable operation of the battery system under high and low temperatures, vibration and complex working conditions.

In order to adapt to the assembly needs of different end products, batteries are available in a variety of sizes. Common shapes include cylindrical, square and soft-packed cells. When integrating CTP/CTC integrated battery packs, there are dual requirements: mechanical fixation of cells + charge and discharge heat extraction. For the bonding needs of cells of different shapes, MCOTI series products can be used to effectively solve various bonding challenges during the battery pack assembly process.

The square aluminum shell power battery uses fast-response PU structural adhesive, which has a fast curing speed and can quickly dissipate a large amount of heat generated by fast charging of the battery core, accurately control the module temperature difference, and reduce the risk of thermal runaway;

Cylindrical power batteries can use acrylic thermally conductive structural adhesive, which has both stable thermal conductivity and high peel strength. It is suitable for large cylindrical CTC integrated chassis solutions and meets the automated glue coating assembly of batch modules;

The soft-packed laminated power battery uses PU structural glue for flexible buffering and heat conduction; it is suitable for large-capacity energy storage soft-packed batteries. The highly elastic adhesive layer can absorb the expansion and deformation of the soft-packed cells during charging and discharging, while balancing the heat dissipation of the module.
