Electroflight’s vision is to be the world leader in the electrification of aerospace. Their focus is around the design and manufacturing of bespoke, safe, certification ready energy storage systems across the aerospace electrification system. Electroflight's all-electric 'Spirit of Innovation' designed in partnership with Rolls-Royce and YASA, is officially the world's fastest all electric aircraft, having set two world records in early 2022.
When looking at Lord’s CoolTherm® thermal management portfolio, they needed a solution that could offer structural support while also providing thermal conductivity to keep the battery cool and prevent it from overheating. Batteries operating at optimum temperature result in better efficiency and longer lifespan.
"High integrity cell bonding is critical to delivering safe, lightweight and reliable battery systems for aerospace," says Electroflight's Senior Battery Design Engineer, Matthew Moore.
As the leader in electrification solutions and thermal management, we were able to match them with an adhesive that met their key requirements.
The best technology alone doesn’t ensure success. We focus on collaboration from the very start. Among electric aircraft, there is little standardization in the design of the most critical component – battery packs.
From different cell chemistries and form factors to different performance requirements, no two designs are the same. By working closely with Electroflight, we were able to understand their unique challenges and aspirations for their first-ever electric plane.
Key requirements for the thermal interface material were:
What attracted Electroflight to our CoolTherm® portfolio of thermal management solutions was the ability to use one product to achieve both bonding and removal of heat. To accomplish this, they used CoolTherm® TC-2002. This product is a two-component adhesive that has 1.0 W/m·K thermal conductivity and a low coefficient of thermal expansion.
Electroflight was able to address four main areas of concern by introducing CoolTherm TC-2002 into their design:
Parker Lord customers have access to a team of global Application Engineers. This allows both teams to communicate, engage with and support each other from around the globe. Our Application Engineers garnered in-depth knowledge of Electroflight’s project, which expedited material requirements, testing, production, and on-site troubleshooting of this adhesive.
"We are very happy that we partnered with Lord in our initiative to ease assembly of our batteries while decreasing operating temperatures in our first electric aircraft. The benefits of the CoolTherm thermal managment portfolio in combination with continued processing and technical support have been pivotal in the development and delivery of our battery solutions."
