  • Patent number: 11646425
    Abstract: A battery having an electrode assembly comprising a cathode having a cathode collector coated, partially or entirely, with a cathode active material, an anode having a nano-web layer on both sides of an anode collector coated, partially or entirely, with an anode active material, and a separation membrane interposed between the cathode and the anode; an electrolytic solution; and an exterior material which encapsulates the electrolyte solution and the electrode assembly together. Since the battery has a porous nano-web layer, even if the temperature inside the battery increases to cause shrinkage or melting of the separation membrane, a contact between the cathode and the anode is prevented such that ignition and/or explosion of the battery does not occur, ion exchange is not disturbed such that the battery performance does not deteriorate, and the nano-web layer is not molten or released towards the separation membrane even at high temperatures.

  • Publication number: 20070111074
    Abstract: Disclosed is an ionic conductor comprising a metal composite oxide characterized by comprising oxygen defects and metal defects in a cryolite lattice. An electrochemical device comprising the ionic conductor is also disclosed. The metal composite oxide has an improved ion conductivity, because formation of an open space within a lattice is ensured by the defects of metal ion sites in the lattice. Therefore, the metal composite oxide is useful for an ionic conductor or an electrochemical device requiring ionic conductivity.

  • Publication number: 20060051278
    Abstract: Disclosed is metal composite oxides having the new crystal structure. Also disclosed are ionic conductors including the metal composite oxides and electrochemical devices comprising the ionic conductors. The metal composite oxides have an ion channel formed for easy movement of ions due to crystallographic specificity resulting from the ordering of metal ion sites and metal ion defects within the unit cell. Therefore, the metal composite oxides according to the present invention are useful in an electrochemical device requiring an ionic conductor or ionic conductivity.
