The structural battery composite is a class of composite materials with ability to provide mechanical integrity in a structural system while simultaneously store electrical energy (i.e. work as a battery). In this paper a framework to estimate the mechanical and electrical performance of laminated structural battery composites is proposed.
Specifically, multifunctional composites within structural batteries can serve the dual roles of functional composite electrodes for charge storage and structural composites for mechanical load-bearing.
The research areas addressed include: carbon fibre electrodes, structural separators, multifunctional matrix materials, device architectures and material functionalization. Material characterization, fabrication and validation are also discussed. The paper focuses on a patented battery composite material technology.
Structural batteries can be made using a traditional laminated battery architecture similar to that of a fibre reinforced polymer composite laminate in which the positive electrode is also reinforced with carbon fibres coated with lithium iron phosphate. Figure 2. Structural battery aircraft structure.
Both conventional batteries and composites are laminated structures. However, there is an inherent problem to make laminated structural battery composites: the use of a solid polymer electrolyte/matrix material. Wetzel (2004) and his team at ARL developed the first laminated structural battery composite material.
Wetzel (2004) and his team at ARL developed the first laminated structural battery composite material. ARL built a device using a metal mesh coated with a positive electrode material, a carbon fibre fabric acting as a negative electrode, a fibre glass separator layer, and a structural solid block co-polymer electrolyte matrix (Wong et al 2007).
