Electrochemical cells with sulphur electrode and reversible dual-ion charge transfer

摘要

The invention concerns an electrochemical cell made of an electrode with a smaller electrode and an electrode with a higher redox potential compared to a reference electrode system M-124M; M+ and an electrolyte, the electrode with the lower redox potential being an electrode with sulphur as an active material, the electrode with the higher redox potential includes an electrode with an anion-absorbing active material;during loading/unloading, both the electrolyte's cations into the electrode with the lower and the anions into the electrode with the higher redox potential are deposited and deposited. Furthermore, the present invention concerns the use of the electrochemical cell of the invention in an alkali based on the dual-ion mechanism,Erdalkali,Aluminium or zinc-based energy storage.
