Frequently Asked Questions about Cylindrical Cell Adhesives
What are the challenges of cylindrical cell adhesives used in electric vehicles
The efficiency of the assembly line is one of the most critical challenges for the adhesive in the OEM production process. Firstly, a cylindrical cell doesn’t pack as efficiently as prismatic and pouch cells. Due to its circular cross-section, the cylindrical cell pack is larger and heavier than other cells types. Thus, the curing speed at room temperature and the bonding strength (cell-to-cell and cell-to module) are essential characteristics of cylindrical cell adhesion.
Which adhesive technology could be used for cylindrical cell assembly?
You may need an adhesive compatible with a fully automated process, short curing times, and multi-substrate adhesion for the cylindrical cell assembly. Acrylic adhesives (MMA) are suitable thanks to their short setting time, multi-surface bonding, and high bonding strength. Other technologies such as UV curing (UV acrylic, UV cyanoacrylate) can also be used.
What are Methyl Methacrylate MMA adhesives?
Methyl methacrylates (MMA) are structural adhesives adapted to bond metals, plastics, and composites. Bostik’s MMAs are designed to be tough, flexible, easy to use, and are made of resin and hardener. Most MMAs also contain rubber and strengthening agents.
They cure quickly at room temperature and have high bonding strength shortly after application. They also resist shear, peel, and stress. As a result, MMA is a good option for assembling cylindrical cells.
Bostik MMA SAF range mainly consists of unmatched impact resistance and flexibility performance. This is possible thanks to our patented MMA adhesives using specific tailor-made Nanostrength® (Acrylic-block-copolymers tougheners) by Arkema.
