Structural batteries – enabling more sustainable aircraft

Activity: Talk or presentation / LecturePresentation at a scientific conference / workshop

Description

Multi-functional electrical energy storage or so-called structural batteries aim at implementing energy storage within loadbearing structures. This technology offers considerable weight and cost savings compared to functional separation and is considered one of the key building blocks for realizing more electric aircraft.
The main challenge relies in finding an alternative to the highly flammable, toxic and environmentally hazardous liquid electrolyte used in conventional lithium-ion batteries. One approach relies in immobilizing poorly flammable ionic liquid electrolytes by gelation using high performance polymers, resulting in inherently safe and scalable structural electrolytes.
For refining the properties of the electrolytes, addition of filler materials offer a vast design space. Improvements of the electrochemical and/or mechanical properties of the electrolyte can be achieved by a rational selection of suitable fillers. In this study we investigated the impact of active filler materials on the electrochemical and mechanical properties of the resulting electrolytes and compared them with inactive ones. Furthermore, we explored the possibility to add 1D filler materials for increasing the mechanical properties of the gel electrolytes. The obtained data allows to draw a map, which enables a more rational gel electrolyte design for structural batteries.
This talk will also look into the potential of multifunctional electrical energy storage for next generation commercial aircraft.
