Abstract: Disclosed are an electrode assembly for sulfur-lithium ion batteries that uses a lithium-containing compound as a cathode active material and a sulfur-containing compound as an anode active material and a sulfur-lithium ion battery including the same.

Abstract: The present invention provides a battery management apparatus and method which connect a plurality of batteries having different energy densities to each other and control power supplied through the plurality of batteries to control the driving of the driving body.

Abstract: The present invention relates to a cathode active material for a lithium-sulfur battery and a method of preparing the same, and more particularly, to a cathode active material for a lithium-sulfur battery comprising: an amphiphilic polymer comprising hydrophilicity parts and hydrophobicity parts; and a sulfur-carbon composite, and a method of preparing the same. When a lithium-sulfur battery is prepared using the cathode active material, there is an effect which may enhance the electric conductivity in an electrode, cycle characteristics and capacity.

Abstract: The present disclosure relates to a lithium electrode, comprising a porous metallic current collector; and lithium metal inserted into pores present in the metallic current collector. The lithium electrode according to the present disclosure can increase contact surface between lithium metal and a current collector to improve the performances of a lithium secondary battery, and can exhibit uniform electron distribution therein to prevent the growth of lithium dendrites during the operation of a lithium secondary battery, thereby improving the safety of a lithium secondary battery.
