Wall#E: Fibre-Reinforced Spacecraft Walls for Storing Energy


The idea behind Wall#E involves integrating energy storage functions into the support structures of spacecraft, which will significantly reduce the mass and volume of satellites without sacrificing performance. To this end, Wall#E utilises fibre-reinforced structures (which enjoy more and more popularity in aerospace engineering) infiltrated with innovative solid-state battery materials. While this project‘s initial focus is on satellites, the underlying concept can easily be adapted to launch systems, space stations, and ground-based e-mobility applications.

  • Reduced satellite mass
  • Simpler, more compact constructions
  • Lower costs of development/Launch
