Manufacturing techniques for composite structure batteries: laminates and sandwich panels

The laminated and sandwich composite structural batteries can efficiently store energy and bear loading while effectively saving mass and volume. To prepare these two types of composite structure batteries, an experimental platform of vacuum-assisted resin transfer process was constructed, and the preparation processes of laminated and sandwich plates were studied. The comparative analysis of the open-circuit voltage with SOC at different temperatures demonstrated the stability and reliability of the preparation processes for composite structure batteries.
