| Abstract Scope |
New battery technologies are necessary to cover the increasing demand in the green transition, and the novel Na-ZnCl<sub>2</sub> battery has been suggested as a solution to a cheap SALT battery, exploiting abundant materials such as Na and Zn. It is, however, important to develop a recycling route for new batteries, making sure that end-of-life products do not go to landfill, and that the materials used can be reused for the same or different applications. The present study has therefore investigated how Na-ZnCl<sub>2</sub> battery cells can be safely decommissioned and recycled. Characterization of the disassembled battery components has been carried out, and it is concluded that the electrode materials and current collectors can be integrated in today’s recycling process of the state-of-the-art Na-NiCl<sub>2</sub> battery. This is also the case for solid β’’-Al<sub>2</sub>O<sub>3</sub> membrane and the liquid NaAlCl<sub>4</sub> electrolyte. |
