CCDC ARL

A structural battery includes an anode, cathode and electrolyte which, taken collectively, have sufficient mechanical strength to allow the battery to be used as a structural component of an article of manufacture. The combined anode, cathode and electrolyte have a stiffness between 10 MPa-1000 GPa, and in certain instances have a stiffness between 50 MPa-100 GPa. Also disclosed are solid electrolytes which may be used in structural batteries. The electrolytes are comprised of salts dissolved in a solvent such as a body of polymeric material. The electrolyte has good ionic conductivity and good mechanical properties. The solid electrolyte may be comprised of a body of uncrosslinked polymer or an at least partially crosslinked polymer such as a multifunctional polymer having segments comprised of linear resins and segments comprised of crosslinking resins. Also disclosed are methods for manufacturing the structural batteries.
