摘要： The present invention relates to a negative electrode for lithium secondary battery and a lithium secondary battery including the same. The negative electrode includes a negative electrode active layer comprising lithium, and a protective layer disposed on the negative electrode active layer, wherein the protective layer comprises a polymer matrix having a three dimensional crosslinked network structure of polymer or includes a non-crosslinked linear polymer, and an electrolyte in the polymer matrix in the amount of 100 to 1000 parts by weight based on 100 parts by weight of the polymer matrix. The negative electrode according to the present invention has no concern about loss of electrolyte and the resulting deterioration of battery life characteristics even during the repetitive charging/discharging of the battery and has improved battery stability due to the inhibition of growth of lithium dendrite.

摘要： There is provided a bipolar laminated all-solid-state lithium-ion rechargeable battery including bipolar electrodes and solid electrolyte layers that are alternately laminated. When viewed from a lamination direction of the battery, a current collector layer of each bipolar electrode has its outer edge inside the outer edge of a positive electrode layer and a negative electrode layer of the bipolar electrode. At least one of the positive electrode layer and the negative electrode layer of each bipolar electrode is provided with at least one electrical insulating portion in an outer edge region on the surface where it is in contact with the current collector layer of the bipolar electrode. When each bipolar electrode is viewed from the lamination direction, the perspective projection of the at least one electrical insulating portion configures the entire periphery of the outer edge. The bipolar electrodes and the solid electrolyte layers form a sinter-bonded body.

摘要： A multilayer conductive film includes a layer 1 including a conductive material containing a polymer material 1 having an alicyclic structure and conductive particles 1 and a layer 2 including a material having durability against positive electrode potential. The multilayer conductive film has stability in an equilibrium potential environment in a negative electrode and stability in an equilibrium potential environment in a positive electrode, has low electric resistance per unit area in the thickness direction, and has excellent barrier properties for a solvent of an electrolytic solution. A battery including a current collector employing the multilayer conductive film can achieve both weight reduction and durability.

摘要： The present invention provides a battery or supercapacitor current collector which is prelithiated. The prelithiated current collector comprises: (a) an electrically conductive substrate having two opposed primary surfaces, and (b) a mixture layer of carbon (and/or other stabilizing element, such as B, Al, Ga, In, C, Si, Ge, Sn, Pb, As, Sb, Bi, Te, or a combination thereof) and lithium or lithium alloy coated on at least one of the primary surfaces, wherein lithium element is present in an amount of 1% to 99% by weight of the mixture layer. This current collector serves as an effective and safe lithium source for a wide variety of electrochemical energy storage cells, including the rechargeable lithium cell (e.g. lithium-metal, lithium-ion, lithium-sulfur, lithium-air, lithium-graphene, lithium-carbon, and lithium-carbon nanotube cell) and the lithium ion based supercapacitor cell (e.g, symmetric ultracapacitor, asymmetric ultracapacitor, hybrid supercapacitor-battery, or lithium-ion capacitor).
