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

A non-aqueous electrochemical cell including a lithium anode, a solid cathode, a first separator and a second separator disposed between the anode and the cathode, and an electrolyte in fluid communication with the anode, the cathode, and the first and the second separators, the first separator having a higher melting point (or shut-down) temperature than the melting point (or shut-down) temperature of the second separator.

High energy density non-aqueous electrochemical cell with extended operating temperature window

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.

Lithium-sulfur battery and methods of preventing insoluble solid lithium-polysulfide deposition

The present disclosure relates generally to a high capacity cathode material suitable for use in a non-aqueous electrochemical cell that comprises copper manganese oxide, which may be in amorphous or semi-crystalline form, and optionally fluorinated carbon. The present disclosure additionally relates to a non-aqueous electrochemical cell comprising such a cathode material and, in particular, to such a non-aqueous electrochemical cell that can deliver a higher capacity than conventional cell.

Non-aqueous cell having amorphous or semi-crystalline copper manganese oxide cathode material

The present disclosure relates generally to indicating an end of life condition of an electrochemical device, and more particularly to systems and methods for sensing and determining an end of life condition in a cell comprising a high capacity cathode material suitable for use in a non-aqueous electrochemical cell. The high capacity cathode material has an amorphous or semi-crystalline form of copper manganese oxide, and optionally fluorinated carbon. The present disclosure additionally relates to transmitting the determined end of life condition to a user or monitoring device of the cell.

End of life indication system and method for non-aqueous cell having amorphous or semi-crystalline copper manganese oxide cathode material

An improved cathode suitable for lithium-sulfur batteries, a battery including the cathode, and a battery including a separator containing inorganic fillers are disclosed. The cathode includes sulfur and a metal oxide and optionally includes an additional polymeric material. The metal oxide reduces dissolution of sulfur at the cathode and reduces sulfur-containing deposits on the battery anode, thereby providing a battery with relatively high energy density and good partial discharge performance. The separator also reduces unwanted diffusion of sulfur species.
