方案优势

The automotive industry is moving towards a brighter, more positive, and sustainable future, with lightweight design, structural bonding, and optimized thermal management of power batteries being the key to addressing the "mileage anxiety", "safety anxiety", and "charging anxiety" of electric vehicles.

Adhesives are used to bond the same or different materials for bonding, thermal conductivity, sealing, or vibration reduction. Battery adhesive is mainly used to meet three major functional requirements:

Structural adhesive
Bonding different battery components or modules, taking into account a certain degree of thermal conductivity, is used for bonding between cells, bonding between cells and side panels, fixing the bottom of the battery, fixing the battery bracket, and so on.

Thermal conductive adhesive
Conducting the heat generated during the operation of the battery cell to the external heat dissipation components, while also taking into account the structural bonding requirements, for heat conduction between the cooling plate and the battery module, as well as between the battery cell and the battery pack.

Sealing and potting adhesive
Long term sealing and sealing of important components to resist the invasion of liquids and gases, and to withstand collision impacts, used for sealing the upper and lower covers of battery packs, etc.

Based on the leading enterprise in the Chinese adhesive industry and the innovation and industrialization advantages of organic silicone, polyurethane, epoxy and other professional adhesives, Zhijiang Company has the qualifications of a national high-tech enterprise and a national enterprise technology center. Relying on national CNAS laboratories and national postdoctoral research workstations, and with the assistance of international experts, it can provide excellent organic silicone for the structural bonding, thermal bonding, and thermal management of power batteries Polyurethane, epoxy adhesive, modified adhesive and other series of products provide high-performance product guarantee for the long-term operation of batteries.
