Structural batteries for efficient vehicles
The project aims at development of structural batteries, i.e. structural polymer composite materials with intrinsic electrochemical energy storing capability. Such devices are desired for their potential to both reduce weight and provide the energy needs for future electric vehicles. Carbon fibres are particularly attractive for this type of multifunctional use as they commonly are used in high performance reinforcements and additionally have the ability to intercalate and coordinate Li-ions. The design approach is relatively new and faces significant research challenges. However, storage capacity of carbon fibres structural batteries with a gravimetric energy density well in parity with state-of-the-art battery cells for electric vehicles are within reach. The project will rely on intense collaboration between different disciplines and will be conducted by four graduate students and two post-docs under joint supervision of an experienced team of scientists.
