摘要： Articles and methods including layers for protection of electrodes in electrochemical cells are provided. As described herein, a layer, such as a protective layer for an electrode, may comprise a plurality of particles (e.g., crystalline inorganic particles, amorphous inorganic particles). In some aspects, at least a portion of the plurality of particles (e.g., inorganic particles) are fused to one another. For instance, in some aspects, the layer may be formed by aerosol deposition or another suitable process that involves subjecting the particles to a relatively high velocity such that fusion of particles occurs during deposition. In some cases, the protective layer may be porous.

摘要： Sulfur-based electrodes, and associated systems and methods for their fabrication, are generally described. Certain embodiments relate to sulfur-based electrodes with smooth external surfaces. According to some embodiments, relatively large forces can be applied to compositions from which the sulfur-based electrodes are made during the fabrication process. In some such embodiments, the compositions can maintain relatively high porosities, even after the relatively large forces have been applied to them. Methods in which liquids are employed during the electrode fabrication process are also described.

摘要： Electrode structures and methods for making the same are generally described. In certain embodiments, the electrode structures can include a plurality of particles, wherein the particles comprise indentations relative to their convex hulls. As the particles are moved proximate to or in contact with one another, the indentations of the particles can define pores between the particles. In addition, when particles comprising indentations relative to their convex hulls are moved relative to each other, the presence of the indentations can ensure that complete contact does not result between the particles (i.e., that there remains some space between the particles) and that void volume is maintained within the bulk of the assembly. Accordingly, electrodes comprising particles with indentations relative to their convex hulls can be configured to withstand the application of a force to the electrode while substantially maintaining electrode void volume (and, therefore, performance). Particles having indentations relative to their convex hulls also occupy a relatively small volume, compared to spheres or other particles including boundaries that fill substantially all of their convex hulls, allowing one to introduce a desired amount of void volume while reducing the percentage of volume within the electrode occupied by particulate material.

摘要翻译： 通常描述电极结构及其制造方法。 在某些实施方案中，电极结构可以包括多个颗粒，其中颗粒包括相对于其凸包的凹痕。 当颗粒彼此接近或接触时，颗粒的凹陷可以限定颗粒之间的孔。 另外，当包含相对于它们的凸包的凹痕的颗粒相对于彼此移动时，凹陷的存在可以确保在颗粒之间不产生完全接触（即，在颗粒之间保留一些空间） 体积保持在组件的主体内。 因此，包括相对于它们的凸包的凹陷的颗粒的电极可被配置为承受对电极施加的力，同时基本上保持电极的空隙体积（和因此的性能）。 与球体或其他颗粒相比，具有相对于其凸包的凹陷的颗粒也占据相对较小的体积，包括基本上填充其所有凸包的边界的边界，允许引入所需量的空隙体积同时减少 电极被颗粒材料占据。

摘要： Composite structures including an ion-conducting material and a polymeric material (e.g., a separator) to protect electrodes are generally described. The ion-conducting material may be in the form of a layer that is bonded to a polymeric separator. The ion-conducting material may comprise a lithium oxysulfide having a lithium-ion conductivity of at least at least 10−6 S/cm.
