LITHIUM-SULFUR BATTERY AND METHODS OF REDUCING INSOLUBLE SOLID LITHIUM-POLYSULFIDE DEPOSITIONS

摘要

An improved electrolyte including a strontium additive suitable for lithium-sulfur batteries, a battery including the electrolyte, and a battery including a separator containing a strontium additive are disclosed. The presence of the strontium additive reduces sulfur-containing deposits on the battery anode, thereby providing a battery with relatively high energy density and good partial discharge performance.
