    • Articles, systems, and methods related to the configuration of electrically non- conductive materials and related components in electrochemical cells are generally described. Some inventive electrochemical cell configurations include an electrically non-conductive material (e.g., as part of the electrolyte) that is configured to wrap around the edge of an electrode to prevent short circuiting of the electrochemical cell. In some embodiments, the electrically non-conductive material layer can be arranged such that it includes first and second portions (one on either side of an electrode) as well as a third portion adjacent the edge of the electrode that directly connects (and, in some cases, is substantially continuous with) the first and second portions. The electrically non- conductive material layer can be relatively thin while maintaining relatively high electrical insulation between the anode and the cathode, allowing one to produce an electrochemical cell with a relatively low mass and/or volume. The arrangements described above can be formed, for example, by forming a multi-layer structure comprising an electrode and an electrically non-conductive material layer (e.g., as a coating), and folding the multi-layer structure such that the electrically non-conductive material covers the convex surface portion of the resulting crease.
    • 通常描述与电化学电池中的非导电材料和相关组分的配置相关的制品,系统和方法。 一些本发明的电化学电池构造包括被配置为围绕电极的边缘缠绕的非导电材料(例如,作为电解质的一部分),以防止电化学电池的短路。 在一些实施例中,非导电材料层可以被布置成使得其包括第一和第二部分(一个在电极的任一侧上)以及与电极的边缘相邻的第三部分,其直接连接(和, 一些情况,基本上连续)第一和第二部分。 电非导电材料层可以相对较薄,同时在阳极和阴极之间保持相对较高的电绝缘,从而允许产生具有相对较低质量和/或体积的电化学电池。 上述布置可以例如通过形成包括电极和非导电材料层(例如,作为涂层)的多层结构而形成,并且折叠多层结构, 导电材料覆盖所产生的折痕的凸表面部分。

    • Methods and articles relating to separation of electrolyte compositions within lithium batteries are provided. The lithium batteries described herein may include an anode having lithium as the active anode species and a cathode having sulfur as the active cathode species. Suitable electrolytes for the lithium batteries can comprise a heterogeneous electrolyte including a first electrolyte solvent (e.g., dioxolane (DOL)) that partitions towards the anode and is favorable towards the anode (referred to herein as an "anode-side electrolyte solvent") and a second electrolyte solvent (e.g., 1,2 - dimethoxyethane (DME)) that partitions towards the cathode and is favorable towards the cathode (and referred to herein as an "cathode-side electrolyte solvent"). By separating the electrolyte solvents during operation of the battery such that the anode- side electrolyte solvent is present disproportionately at the anode and the cathode-side electrolyte solvent is present disproportionately at the cathode, the battery can benefit from desirable characteristics of both electrolyte solvents (e.g., relatively low lithium reactivity of the anode-side electrolyte solvent and relatively high polysulfide solubility of the cathode-side electrolyte solvent).
    • 提供了关于在锂电池中分离电解质组合物的方法和制品。 本文所述的锂电池可以包括具有锂作为活性阳极物质的阳极和具有硫作为活性阴极物质的阴极。 用于锂电池的合适电解质可以包括非均相电解质,其包括朝向阳极分隔并且有利于阳极(在本文中称为“阳极侧电解质溶剂”)的第一电解质溶剂(例如,二氧戊环(DOL)),以及 第二电解质溶剂(例如,1,2-二甲氧基乙烷(DME)),其分隔成阴极并且有利于阴极(并且在本文中称为“阴极侧电解质溶剂”)。 通过在电池操作期间分离电解质溶剂使得阳极侧电解质溶剂在阳极处不成比例地存在,并且阴极侧电解质溶剂在阴极处不成比例地存在,电池可以受益于两种电解质溶剂的期望特性( 例如阳极侧电解质溶剂的锂反应性相对较低,阴极侧电解质溶剂的多硫化物溶解度相对较高)。
