    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 an electrode assembly manufacturing process comprising the following steps. First, wrapping a second separator around a laminate structure having alternating layers of positive electrodes, first separators, and negative electrodes. Second, simultaneously pressing the upper end and the lower end of the laminate structure including the second separator-3-2 to strengthen the adhesive strength between each layer of the laminate structure. Third, bonding the excess portions of the second separator-3-2 surrounding the structure, thereby adjusting to meet the standard requirements of the laminate structure. And fourth, bonding each of the bonded portions of the second separator to a respective adjacent portion of the second separator in the lateral dimension. The electrode assembly manufacturing process minimizes damage to the initial structure and allows the wrapping to suit the size of the structure, thereby increasing the utilization value of the electrode assembly.

    摘要: New, improved or optimized battery separators, components, batteries, industrial batteries, inverter batteries, batteries for heavy or light industrial applications, forklift batteries, float charged batteries, inverters, accumulators, systems, methods, profiles, additives, compositions, composites, mixes, coatings, and/or related methods of water retention, water loss prevention, improved charge acceptance, production, use, and/or combinations thereof are provided or disclosed. More particularly, the present invention is directed to one or more improved battery separators having various improvements that may result in decreased water loss for a battery in which such a separator is incorporated, enhanced charge acceptance, or combinations thereof. Additionally, the present invention relates to one or more improved battery separators having various improvements with regard to shape, and/or physical profile, and/or chemical(s), additives, mixes, coatings, and/or the like used to make such battery separators (such as oil(s), and/or chemical additive(s) or agents used to coat, finish or improve such battery separators (such as surfactant(s))). The improved battery separators of the instant invention are particularly useful in or with industrial batteries, such as inverter batteries, batteries for heavy or light duty industrial applications, and so forth.

    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: An outer edge of a negative electrode (200) covered with a first adhesive member (410) is substantially aligned with an outer edge of a positive electrode (100) covered with the first adhesive member (410) in a direction from a stacked body (10) toward the first adhesive member (410) or a direction from the first adhesive member (410) toward the stacked body (10). Specifically, the outer edge of the negative electrode (200) covered with the first adhesive member (410) is positioned within a distance equal to or more than 0% and equal to or less than 200% of a thickness of the negative electrode (200) from the outer edge of the positive electrode (100) covered with the first adhesive member (410) in the above direction.
