ALKALI METAL-SULFUR SECONDARY CELL |
摘要 |
[Problem to be Solved] The present invention provides an alkali metal-sulfur-based secondary battery in which coulombic efficiency is improved by suppressing a side reaction during charge, and a reduction in discharge capacity by repetition of charge and discharge is suppressed and which has a long battery life and an improved input/output density. [Solution] The alkali metal-sulfur-based secondary battery includes a positive electrode 2 or a negative electrode containing a sulfur-based electrode active material; an electrolyte solution containing an ether compound such as THF and glyme and a solvent such as a fluorine-based solvent, wherein at least a part of the ether compound and the alkali metal salt forms a complex; and a counter electrode 4. |
