Development of Graphene Batteries for Use in Aviation Applications

This project aims to develop a technology for the preparation of scalable graphene batteries. The anodes are comprised of functionalized graphene sheets with basal plane nanoholes and assembled in a densely-packed covalently-linked framework. The anodes are prelithiated using a commercially scalable process, which enriches the electrodes with Li ions and forms a stable interface for increased cycling stability. The fabricated graphene-based anodes are assembled in full cells with standard cathodes to demonstrate energy density capability and cycling performance (500-1,000 cycles in Phase I). Both coin cells and pouch cells will be assembled and tested using standard electrochemical techniques.
