Abstract
Abstract This research focuses on the simultaneous maintenance of mechanical and electrochemical properties of laminated structural batteries (LSBs), using co‐continuous structural electrolytes and carbon fiber‐reinforced plastic (CFRP) composites. A comparison is made between the electrochemical performance of LSB encapsulated by glass fabric composites and those directly integrated into coin cells. The electrochemical properties of LSB with different lay‐up configurations are evaluated using charge/discharge cycling, and tensile/bending tests were carried out to evaluate their mechanical properties. The effect of lay‐up configurations on the multifunctional performance of LSB is also investigated. The results show that the self‐designed encapsulating method improves the load‐carrying capacity of batteries while sacrificing some electrochemical properties. The multifunctional performances of LSB having a CFRP composite anode with [0] 2 lay‐up is the best among the four structures with different lay‐up configurations. Although further research is required to improve the electrochemical properties of LSB, the proposal and verification of this new encapsulating method are a significant contribution in the development of LSB.
