An improved electrolyte including a fire-retardant additive suitable for application in wide temperature cell and/or battery operation with safer cell design, a battery including the electrolyte and a separator optionally containing a fire-retardant additive, improved electrical and thermal conductive electrodes are disclosed. The presence of the fire-retardant additive reduces flammability of the electrolyte and improved the overall safety of the battery.

Electrolyte, a battery including the same, and methods of reducing electrolyte flammability

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.

Lithium-sulfur battery and methods of reducing insoluble solid lithium-polysulfide depositions

An improved lithium-sulfur battery containing a surface-functionalized carbonaceous material. The presence of the surface-functionalized carbonaceous material generates weak chemical bonds between the functional groups of the surface-functionalized carbonaceous material and the functional groups of the polysulfides, which prevents the polysulfide migration to the battery anode, thereby providing a battery with relatively high energy density and good partial discharge efficiency.
