Electrolyte of lithium-sulfur batteries and lithium-sulfur batteries comprising the same

摘要

An electrolyte for use in a lithium-sulfur battery includes salts having imide anions. The electrolyte may further include salts having organic cations. When lithium-sulfur batteries include salts having imide anions as electrolytes, the sulfur utilization is increased, and cycle life characteristics and discharge characteristics such as discharge capacity and average discharge voltage are improved.
