Structural Battery Composites (SBCs) refer to a class of structural power composites designed to provide lightweight energy storage for electrically powered structural systems. Integrating carbon fibers, epoxy resin, or other lightweight, high-strength materials, structural battery composites can store energy in a similar manner to traditional lithium-ion batteries.
While structural battery composites are in the early stages of commercialization, the concept of the technology has evolved over the past couple of decades, driven by advances in materials science, particularly in the fields of composite materials, batteries, and electrochemistry.
Why Structural Battery Composites Matter?
The key driver behind the development of structural battery composites (SBCs) is the potential to accomplish significant weight reductions in various applications.
By removing separate battery enclosures, SBCs offer a path towards lighter and more energy-efficient designs, particularly appealing in industries where weight is a critical factor. Structural Battery Composites can also lead to diversity and decentralized energy material supply chains.
Applications of Structural Battery Composites (SBCs)
Since the structural battery composite is in its infancy, the technology holds immense potential for diverse sectors:
Electric Vehicles (EVs): Imagine a vehicle’s body panels can store energy and function as battery components, boosting range and rigidity while lowering overall vehicle weight.
Aerospace: Structural battery composites could redefine aircraft design by enabling energy-storing fuselages and wing structures. This results in significant fuel savings and enhanced performance, potentially enabling all-electric aircraft in the future.
Drones: Structural battery composite (SBC) wings or fuselages could improve drone frames, doubling drone flight times, making it crucial for applications like surveillance, mapping, and delivery.
