    摘要： A battery cell includes an electrode assembly and a first tab. The electrode assembly includes a separator. An outer surface of the electrode assembly includes a first lateral face and a second lateral face disposed opposite to each other along a first direction, and a first end face and a second end face disposed opposite to each other along a second direction. One end of the first tab is electrically connected to the first electrode plate, and another end of the first tab extends out from the first end face. The first tab includes a first surface and a second surface. The first surface is oriented toward the first lateral face, and the second surface is oriented away from the first lateral face. The first end face includes a first region. The first region is located between the first surface and the first lateral face.

    摘要： An apparatus for manufacturing an electrode assembly includes a separator supply unit, a table, a separator guide, and a pair of upper adhesive supply units. The separator supply unit is configured for supplying a separator sheet from which a separator is formed. The table is configured for supporting an electrode and a portion of the separator sheet. The separator guide is configured for guiding the separator sheet to fold in a particular folding direction. The pair of upper adhesive supply units are configured for applying an adhesive to at least a part of an uppermost electrode supported by the table. The separator guide and the pair of upper adhesive supply units are configured for translation over and relative to the table. The electrode assembly is manufactured by a process using the apparatus.

    摘要： Provided is a technology that can obtain an electricity storage device including a wound electrode body with high productivity. In an aspect of the electricity storage device disclosed herein, a separator has a first adhesive layer and a second adhesive layer on at least one surface of the separator. In plan view of the separator, the first adhesive layer is partially formed, and the second adhesive layer is partially formed. The first adhesive layer is composed of an adhesive layer that exhibits adhesiveness to the positive electrode by contacting the positive electrode facing the first adhesive layer at ordinary temperature. The second adhesive layer is composed of an adhesive layer that has no adhesiveness to the positive electrode when the first adhesive layer adheres to the facing positive electrode, and thereafter exhibits adhesiveness to the positive electrode when some physical means is applied.

    摘要： Described herein are electrode-separator integrated assemblies, lithium-metal electrochemical cells comprising such assemblies, and methods of fabricating such assemblies and cells. An assembly can be formed as one continuous structure comprising one type of electrodes (referred to as an assembly electrode) wrapping around multiple other-type electrodes (referred to as non-assembly electrodes). Either positive or negative electrodes can be assembly electrodes, i.e., parts of electrode-separator integrated assemblies. The assembly also comprises a first separator portion and a second separator portion such that the assembly electrode is positioned between the two separator portions. The separator portions can be adhered to the assembly electrode. The separator portions can be independent separate sheets or parts of a single monolithic sheet wrapping around the inner edges of the assembly electrode. A portion of the assembly electrode extends from the separator portions for making electrical connections to other electrodes and or cell tabs.

    摘要： Regarding a herein disclosed battery, on each of two electrode assemblies, a positive electrode winding-start end part includes a first area elongating along a flat part, and a negative electrode winding-start end part includes a second area elongating along the flat part, and a third area elongating from an end part of the folding part along the flat part. An electrode starting-end laminate part is provided where the area are overlapped in a thickness direction. An electrode starting-end laminate part of the first electrode assembly and an electrode starting-end laminate part of the second electrode assembly are mutually arranged at different sides with respect to a surface being along a wound axis of the first electrode assembly and a wound axis of the second electrode assembly.
