Structural battery composites (SBCs) represent an emerging multifunctional technology in which materials functionalized with energy storage capabilities are used to build load-bearing structural components.
Structural battery composites are one type of such a multifunctional material with potential to offer massless energy storage for electric vehicles and aircraft. Although such materials have been demonstrated, their performance level and consistency must be improved. Also, the cell dimensions need to be increased.

The structural battery composite cells were made from the following materials. A 14 mm wide TeXtreme unidirectional carbon fiber spread tow was used as the negative electrode. The ultrathin spread tow UD tapes of T800SC-12 k-5 °C PAN-based carbon fibers with a linear tow weight of 0.52 g m −1 were supplied by Oxeon AB, Sweden.
However, the composite did not work as a battery due to poor electrical insulation. Later, Ekstedt et al (2010) and Carlson (2013) were able to build working laminated structural battery composites.
