Zircotec, a UK firm, is introducing a high-tech coating for EV batteries that can replace heavy and expensive steel casings with lighter, less expensive materials. This new approach aims to improve the efficiency of cooling plates in lithium-ion batteries, reducing the risk of thermal runaway. The ceramic-based coating allows automakers to use aluminum and polymer composites for battery casings and cooling plates, ultimately cutting costs and weight.
The company already has experience in ceramic thermal coatings through its products used in motorsports like F1 racing. However, to adapt this technology for the EV market, Zircotec has launched a new R&D cycle under the UK Ceramics for BEVs project. This program, with Zircotec as the lead partner for product development, aims to deploy ceramic technology to reduce the cost of EV batteries and produce more efficient vehicles with lighter materials.
Lightweight materials are crucial for improving the performance and efficiency of electric vehicles. The US Department of Energy emphasizes the importance of using lightweight materials in hybrid and electric vehicles to offset the weight of power systems like batteries and electric motors. By using lightweight structural materials, vehicles can carry advanced emission control systems, safety devices, and integrated electronics without increasing overall weight.
In addition to lightweight materials for EV battery casings, there is also a need for lightweight batteries themselves. A study from Chalmers University describes a new lightweight carbon fiber battery that could increase EV driving range by up to 70%. This structural battery design allows the carbon fiber electrode material to act as reinforcement, electrical collector, and active material in the anode and cathode, reducing the weight and cost of the battery.
The Chalmers research team’s work on the carbon fiber battery builds on a breakthrough from 2018, which demonstrated the material’s ability to function as electrodes in lithium-ion batteries. This innovation has the potential to revolutionize the EV battery market by making batteries lighter, more efficient, and sustainable. Carbon fiber replaces traditional materials like copper, aluminum, cobalt, and manganese, offering a more sustainable solution for next-generation batteries.
Overall, the development of lightweight materials and coatings for EV batteries is essential for improving the performance and cost-effectiveness of electric vehicles. By leveraging advanced technologies like ceramic coatings and carbon fiber electrodes, companies like Zircotec and research institutions like Chalmers University are paving the way for a future where EVs are more efficient, affordable, and sustainable. Stay tuned for more advancements in lightweight EV battery technology as the industry continues to evolve.
