Doctor Johanna Xu and Professor Leif Asp from the Chalmers University of Technology in Sweden demonstrate the manufacturing process of a structural battery cell in the composites lab. The cell consists of a carbon fibre electrode and a lithium iron phosphate electrode, separated by a fibreglass fabric, all impregnated with a structural battery electrolyte for combined mechanical and electrical function.
As part of their analysis of a multicell laminate, three structural batteries, each with a nominal voltage of 2.8V, were connected in series and laminated as part of a larger composite laminate. The laminate has a total voltage of 8.4V and a stiffness in the plane of just over 28 GPa.
