The EV battery industry is developing rapidly, pressing the need for advanced materials that are thinner, lighter and safer. Engineers are increasingly turning to mica as an important solution that helps improve vehicle reliability and safety by containing thermal runaway. Pressure-sensitive adhesive (PSA) tapes, meanwhile, have emerged as a popular solution for bonding mica materials to the battery pack.
Our new white paper examines the common challenges associated with using mica. Referring to laboratory data, this report provides guidance to engineers and others involved in the design and assembly of these materials. It provides insight into how PSA tapes offer many benefits when combined with mica for EV battery packs including, but not limited to:
- Safety: PSA tapes do not require special protocols for handling hazardous materials.
- Assembly optimization: PSAs provide raw power almost immediately with a treatment time measured in seconds rather than hours or days. Tapes can also hold parts in place while the package is assembled.
- Consistency: PSAs provide consistent intensity upon application. Each battery pack that comes out of the assembly will have the same amount of adhesive as all the other packs.
- Versatility: PSA tapes can be aminated into foams, strips and films, and cut to specifications. Adhesives can be formulated with properties that improve ease of use (such as ease of removal/reposition), long-term durability and flame resistance
The white paper describes the properties to consider in Muscovite and Phlogopite mica and the effect of paste pattern, tape construction, and peel angle on the properties. This study was developed in partnership with Asheville Mica Energy Solutions.
