Project introduction:

Project_3-1
Utilisation hierarchy

This project aims to develop a product development process for battery systems that enables closed material flows throughout all life phases and thus counteracts the ongoing shortage of raw materials. With regard to the recyclability of current and future cells, modules and packs, the storability, the dismantlability of components and the reparability of materials as well as the technological incompatibility of materials and structural solutions must be considered. With the development of new concepts and design guidelines in mind, it should be possible in the course of the investigations to assess and evaluate recycling scenarios and dismantling strategies and to quantify the influence of certain recycling-orientated measures.

Specific objectives:

  • Establishment of a development process for recycling-friendly battery and system designs (possibility of second- or third-use / recycling as prioritisation).
  • Assessment and evaluation of recycling scenarios and dismantling strategies
  • Integration of suitable sensor technology (smart battery)
  • Enable pure material separation through suitable material selection and dismantling interfaces - Trade off: function integration vs. function separation
  • Modelling of the system environment and the relevant interfaces (holistic system description)

Expected outcome:

  • System model covering all hierarchical levels of battery systems, which interconnects the requirements of the Li-ion battery and the recycling processes in a component-specific context
  • Connecting design options with associated potential environmental impacts
  • Sustainable cell & pack concepts
