Abstract
A process for the disposal of rechargeable storage cells based on sodium and sulphur includes embedding each storage cell in a wax-like, solid material and then opening the storage cells. After opening, the sodium is first removed from the storage cell. Subsequently, the storage cell is opened further, and reaction products, a second reactant and components of the storage cell are taken out for re-utilization or processing to form waste materials that are free of pollutants and capable of disposal.
