    摘要： Electrolyte materials for use in electrochemical cells, electrochemical cells comprising the same, and methods of making such materials and cells, are generally described. In some embodiments, the materials, processes, and uses described herein relate to electrochemical cells comprising sulfur and lithium such as, for example, lithium sulfur batteries. The electrolyte can comprise a polymeric material and, in some cases, an absorbed auxiliary material. For example, the electrolyte material can be capable of forming a gel, and the auxiliary material can comprise an electrolyte solvent. In some instances, the electrolyte material can comprise at least one organic (co)polymer selected from polyethersulfones, polyvinylalcohols (PVOH) and branched polyimides (HPI). The non-fluid material in the electrolyte, when configured for use, can, alone or in combination with the optional absorbed auxiliary material, have a yield strength greater than that of lithium metal, in some embodiments.

    摘要： 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).

    摘要： 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.
