Designing new batteries with end-of-life in mind can improve recyclability. But to keep the batteries marketable, the collaboration must develop new designs that trade minimal loss in energy-density performance for the ability to use cheaper, new recycling processes at end of life.

The center collaboration will explore new designs for wound, prismatic, and pouch cells that enables them to be flushed clean of waste materials at end-of-life and refilled for use as reconstituted components in new batteries. To enable this flush-and-fill concept, new cell geometries will be designed and tested. A rinse liquid will be flushed through cathode and anode to renew the surface before adding new electrolyte.

This area of the ReCell Center has room for growth. As new ideas/projects are identified they will be added to this focus area and investigated.

Learn more about the individual projects in these areas in our Quarterly Reports.

One potential new configuration is shown here of a multiple cell designs with added external port(s) or oversized packaging of cells for injecting fresh electrolyte and rinsing SEI on the aged electrodes. This could aid the flowability of solution (i.e., electrolyte) in spent cells for rejuvenation.
