    Abstract: Electrochemical cells for lithium-sulfur batteries include a cathode comprising a sulfur containing material, an anode comprising lithium, a separator between the anode and cathode and an interlayer extending from a perimeter of the separator in a direction perpendicular to a stacking direction. The interlayer is configured to prevent polysulfide migration from the cathode to the anode.

    Abstract: A method of making an electrode for a lithium ion battery includes providing a restricting media having a main body with opposing planar surfaces and depositing alloying particles on the opposing planar surfaces to form a restrained active particle layer. The restricting media can be a magnetic, electrochemically inactive material with an affinity for the alloying particles. The restricting media restrains expansion of the alloying particles during lithiation to a respective side of the restricting media. Electrodes include a current collector and an electrode material layer adjacent the current collector including the restricting media, the alloying particles deposited on the restricting media to form a restrained active particle layer, and a carbon material in contact with the alloying particles.

    Abstract: Methods and apparatus are provided for discharging a Li—S battery having at least one battery unit comprising a lithium-containing anode and a sulfur-containing cathode with an electrolyte layer there between. One method comprises electrochemically surface treating the sulfur-containing cathode during discharge of the battery. A method of electrochemically surface treating a cathode of a lithium-sulfide battery comprises applying at least one oxidative voltage pulse during a pulse application period while the lithium-sulfur battery discharges and controlling pulse characteristics during the pulse application period, the pulse characteristics configured to affect a morphology of lithium sulfide forming on the sulfur-containing cathode during discharge.

    Abstract: Electrodes having at least one current correcting layer between the current collector and the separator drive electron flow in a direction perpendicular to the X-Y plane. Such an electrode includes a current collector, a first active material layer coated on the current collector, a first current correcting layer on the first active material layer opposite the current collector and a second active material layer on the first current correcting layer opposite the first active material layer. The first current correcting layer is a highly conductive, porous material that is not electrochemically active, the first current correcting layer being uniformly formed along an X-Y plane of the electrode.
