Abstract [en]

In this article a novel energy-storing composite electrode is investigated with regards to its mechanical and electrochemical properties. This composite electrode consists of carbon fibers, which provide both the mechanical reinforcement and the negative electrode in the battery cell. Also, this carbon fiber composite electrode consists of a polymer matrix that can conduct lithium ions, in order to simultaneously act as the electrolyte in the battery cell.

Electrochemical tests were performed on the manufactured composite electrode and show extremely promising results for the battery performance. Furthermore, mechanical tests show that the composite electrode has acceptable mechanical properties for structural use.

It is shown that the internal distances in the composite are large, and volume fraction of fibers is low. This is not only significantly limiting the mechanical properties of the composite, but also the electrochemical properties.

Overall, the carbon fiber composite electrode is found to have suitable characteristics for further research, where many further research topics are found in order to improve and characterize the composite further.
