- Lithium-sulfur dioxide secondary battery having complex alkali-ion inorganic liquid electrolyte and complex alkali-ion inorganic liquid electrolyte thereof

摘要

The present invention relates to a lithium-sulfur dioxide secondary battery containing a composite alkali ion inorganic liquid electrolyte, and to the composite alkali ion inorganic liquid electrolyte. To this end, the lithium-sulfur dioxide secondary battery comprises: a lithium-containing negative electrode; a carbon material-containing positive electrode; and an inorganic liquid electrolyte containing a composite salt of sulfur dioxide and alkali ion. According to the present invention, it is possible to prevent dendrite formation of lithium metal and also to improve operational performance and stability.
