Abstract: Provided are a separator having an inorganic protective film and a lithium battery using the separator. The separator has suppressed self discharge and reduced internal shorting.

Abstract: Provided is a lithium metal anode having a lithium metal layer and a porous polymer film integrated with a surface of the lithium metal layer. The lithium metal anode further includes a current collector attached to the surface of the lithium metal layer opposite the porous polymer film. The lithium metal anode further includes a protective coating layer between the porous polymer film and the lithium metal layer, the protective coating layer having lithium ionic conductivity and impermeable to an electrolyte.

Abstract: Provided is a cathode electrode including a current collector, and a cathode electrode active material layer laminated on the current collector, a method of making the cathode electrode, and a battery including the cathode electrode. The cathode electrode active material includes particles having a core-shell structure with a sulfur-containing active material core, a conductor coating disposed on a surface of the active material core, and a binder coating disposed on the conductor coating. A high-performance lithium sulfur battery can be manufactured using the cathode electrode, since sufficient bondability can be attained with only a small amount of a binder.

Abstract: Disclosed is a cathode electrode having a cathode active material layer stacked on a current collector. The cathode active material layer includes a porous conductive material having a surface coated with sulfur and/or a sulfur-containing organic compound and/or pores filled with sulfur and/or a sulfur-containing organic compound. A lithium secondary battery employing the cathode electrode also is disclosed. The cathode electrode is structurally stable during charging and discharging since the structure of the cathode active material layer can be maintained even at the phase transition of sulfur during charging and discharging.
