Unveiling the Multifunctional Carbon Fiber Structural Battery (Adv. Mater. 48/2024)

Multifunctional Structural Batteries The concept of massless energy storage is realized by integrating mechanical load-bearing capabilities within the battery, offering the potential to extend vehicle range and reduce energy consumption in transportation. The cover illustration highlights the versatility of structural batteries in cars, ships, airplanes, and the possibility of ultra-thin, credit card-sized mobile phones. In article number 2409725, Chaudhary Richa, Leif E. Asp, and co-workers developed an all-carbon fiber-based structural battery, evaluating its electrochemical and mechanical performance in a dual-phase solid-liquid electrolyte system that provides both structural integrity and efficient ion transport. Present cost-effective approach ensures multifunctionality at every stage–from electrode fabrication to maintaining the mechanical properties of LFP-coated carbon fibers, enhancing rigidity through the biphasic electrolyte, and increasing the battery's overall stiffness.
