Zircotec, the thermal technologists that have owned the science of heat management for more than 30 years, have secured government funding through the Advanced Propulsion Centre UK (APC) to develop a single proprietary ceramic coating that will unlock the use of lightweight materials – including aluminium and plastic composites – across EV battery enclosures and cooling plates.
 
The Government-supported ‘CeraBEV’ (Ceramics for BEVs) project, which forms part of the government’s work to ensure the UK remains at the cutting-edge of battery technology, will last for 12 months. Zircotec has been installed as the lead partner, while Cranfield University is the project partner responsible for coating testing and evaluation.
 
In almost all cases, battery enclosures on today’s EVs are manufactured from heavy-duty steel. In a bid to reduce the weight of EVs and improve their range, alternative and lightweight materials are needed. Examples include aluminium and plastic composites. Alongside this, the efficiency of aluminium cooling plates within the battery pack is hampered by the required electrical insulation coupled with its typically low level of thermal conductivity. Significant improvements in cooling plate efficiency can be achieved through thin, high-performance electrical insulation with enhanced thermal conductivity.

Dominic Graham, Zircotec Engineering Director, said: “The key to unlocking the use of new, lightweight materials across battery enclosures and cooling plates in EVs is being able to develop and effectively apply high-performance coatings that ensure the safe thermal and electrical operation of the substrate. The Advanced Propulsion Centre ‘CeraBEV advanced route to market demonstrator’ project allows our engineers to develop world-first, all-in-one dielectric and flameproof ceramic coatings that will address and overcome the significant thermal management and electrical insulation challenges associated with the lightweight materials OEMs want to use on their vehicles.”
 
Andrew Donachie, Zircotec COO, said: “We’re delighted to be selected to receive this APC funding through APC which will not only enable Zircotec to extend its current ceramic coating expertise within the EV sector, but will also accelerate the UK’s battery energy storage technology capability through ceramic coating research that has the power to transform material use in the battery electric vehicle sector.”
 
Ian Constance, APC CEO, said: “The Advanced Route to Market Demonstrator delivers cutting-edge technology in a short period of time. With the investment from both industry and government, the projects will not only demonstrate the strength and breadth of the zero-emission automotive sector in the UK, but hopefully the acceleration of these to commercialisation. We will certainly see concepts that will go into real-world every-day vehicles, helping the UK achieve its net zero goals.”
