Abstract
Overview

In weight-sensitive applications such as ground and air vehicles with electric propulsion, the energy storage device and the structural frame are usually the heaviest components. Naturally, significant weight saving can be achieved by combining these functionalities through the development of structural energy storage. Besides, the energy density associated with electric vehicles can be significantly increased by replacing the car body parts with structural energy storage parts. However, the introduction of state-of-the-art multifunctional energy storage technologies to the market is predominantly hindered by poor energy density.

Technology

Fig. 1 shows the steps involved in the fabrication of multi-layered ZIHSCs.

  1. Fabrication of unidirectional highly-porous carbon nanofibers via hot-drawing the electrospun PAN: PMMA precursors;
  2. Preparation of the antifreezing electrolyte;
  3. Assembling of the ZIHSCs by blade coating of the zinc foil electrode with the antifreezing electrolyte solution; and
  4. Fabrication of sandwich structure including unidirectional fiber mat, electrolyte and zinc foil.
