Structural battery with record performance (IMAGE)
Caption
Doctor Johanna Xu with a newly manufactured structural battery cell in Chalmers' composite lab, which she shows to Leif Asp. 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. 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.
