ELECTROLYTE ADDITIVE FOR LITHIUM-SULFUR DIOXIDE ELECTROCHEMICAL CELL

摘要

The degradation of organic electrode separators in rechargeable lithium-sulfur dioxide electrochemical cells which utilize chemically uncombined aluminum chloride as an electrolyte component can be reduced by incorporating an additive into the electrolyte which is effective to provide a redox couple having a potential in the range which is above that of the SO2/S2O4-2 couple and below that of the Cl2/Cl- couple.
