    摘要: Disclosed herein is an integrated electrode assembly including a cathode, an anode, and a separation layer disposed between the cathode and the anode. The cathode, the anode, and the separation layer are integrated with each other. The separation layer includes 3 phases including a liquid-phase component containing an ionic salt, a solid-phase component supporting the separation layer between the cathode and the anode, and a polymer matrix in which linear polymers and cross-linked polymers form a viscoelastic structure with the liquid-phase component and the solid-phase component being incorporated in the polymer matrix. The polymer matrix is coupled to each of the cathode and the anode. The liquid-phase component of the separation layer flows into the electrodes (i.e., the cathode and anode) during preparation of the integrated electrode assembly to greatly improve wetting properties of the electrodes and to increase ionic conductivity of the electrodes.

    摘要: 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.

    摘要: Disclosed herein is an electrolyte for lithium secondary batteries comprising: a chelating agent, which forms complexes with transition metal ions in the battery, and at the same time does not react and coordinate with lithium ions; a non-aqueous solvent; and an electrolyte salt, as well as a lithium secondary battery comprising the electrolyte. The chelating agent, which is contained in the electrolyte for lithium secondary batteries, can suppress a side reaction in which transition metal ions are reduced and deposited as transition metals on the anode. Also, the chelating agent can suppress internal short-circuits in the battery and the resulting voltage drop of the battery and a reduction in the safety and performance of the battery, which can occur when transition metals are deposited on the anode.

    摘要: The present invention relates to a lithium secondary battery comprising an overdischarge-preventing agent. Particularly, the present invention provides a lithium secondary battery comprising an overdischarge-preventing agent having superior effects for an overdischarge test and showing 90% or more capacity recovery after the test, by introducing lithium nickel oxide into a cathode for a lithium secondary battery comprising a lithium transition metal oxide capable of occluding and releasing lithium ions as an overdischarge-preventing agent to supply lithium ions such that irreversible capacity of an anode can be compensated or better, thereby lowering voltage of a cathode first to prevent voltage increase of an anode during the overdischarge test.
