| Summary: | Structural batteries not only store energy but also serve as load-bearing components in electric vehicles (EVs), addressing the weight issue and improving efficiency and driving range. Carbon fiber (CF), known for its mechanical strength and electrical conductivity, plays a crucial role in these batteries. However, CF's chemical inertness and smooth surface challenge adhesion and performance. Therefore, interface engineering is essential to optimize material deposition and improve mechanical bonding, using surface modification techniques to enhance CF properties. Results demonstrate a specific capacity of 349 mAh g?¹ at 0.1 A g?¹. At 0.3 A g?¹, the battery retains 77% of its initial capacity over 100 cycles. Mechanical tests show tensile strengths of 310 MPa for the Zn-CF anode and 433 MPa for the MnO2-CF cathode, with the overall battery at 183 MPa. These findings highlight the effectiveness of interface engineering in enhancing both electrochemical performance and mechanical robustness, paving the way for more efficient and durable energy storage solutions in EV applications. |
