    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. 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. In some embodiments, the electrochemical cell (e.g., the electrolyte) can be configured such that the electrochemical cell can be cycled at relatively high temperatures without experiencing thermal runaway.

    摘要： Electrode protection in electrochemical cells, and more specifically, electrode protection in both aqueous and non-aqueous electrochemical cells, including rechargeable lithium batteries, are presented. In one embodiment, an electrochemical cell includes an anode comprising lithium and a multi-layered structure positioned between the anode and an electrolyte of the cell. A multi-layered structure can include at least a first single-ion conductive material layer (e.g., a lithiated metal layer), and at least a first polymeric layer positioned between the anode and the single-ion conductive material. The invention also can provide an electrode stabilization layer positioned within the electrode, i.e., between one portion and another portion of an electrode, to control depletion and re-plating of electrode material upon charge and discharge of a battery. Advantageously, electrochemical cells comprising combinations of structures described herein are not only compatible with environments that are typically unsuitable for lithium, but the cells may be also capable of displaying long cycle life, high lithium cycling efficiency, and high energy density.

    摘要： Li-based anodes for use in an electric current producing cells having long life time and high capacity are provided. In certain embodiments, the Li-based anode comprises at least one anode active Li-containing compound and a composition comprising at least one polymer, at least one ionic liquid, and optionally at least one lithium salt. The composition may be located between the at least one Li-containing compound and the catholyte used in the electric current producing cell. In some embodiments, the at least one polymer may be incompatible with the catholyte. This configuration of components may lead to separation between the lithium active material of the anode and the catholyte. Processes for preparing the Li-based anode and to electric current producing cells comprising such an anode are also provided.
