Structural battery with record performance

This video clip has no sound, which is intentional as it’s intended as raw material for journalists. Manufacturing of a structural battery cell in Chalmers’ composite lab by Doctor Johanna Xu, Chalmers University of Technology, Sweden. 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. Analysis of a multicell laminate manufactured in Chalmers’ composite lab, by Doctor Johanna Xu and Professor Leif Asp. Three structural batteries have been connected in series and laminated as part of a larger composite laminate. Each structural battery cell has a nominal voltage of 2.8 V. The laminate has a total voltage of 8.4 V and a stiffness in the plane of just over 28 GPa.
