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： The present invention relates to the use of porous structures comprising sulfur in electrochemical cells. Such materials may be useful, for example, in forming one or more electrodes in an electrochemical cell. For example, the systems and methods described herein may comprise the use of an electrode comprising a conductive porous support structure and a plurality of particles comprising sulfur (e.g., as an active species) substantially contained within the pores of the support structure. The inventors have unexpectedly discovered that, in some embodiments, the sizes of the pores within the porous support structure and/or the sizes of the particles within the pores can be tailored such that the contact between the electrolyte and the sulfur is enhanced, while the electrical conductivity and structural integrity of the electrode are maintained at sufficiently high levels to allow for effective operation of the cell. Also, the sizes of the pores within the porous support structures and/or the sizes of the particles within the pores can be selected such that any suitable ratio of sulfur to support material can be achieved while maintaining mechanical stability in the electrode. The inventors have also unexpectedly discovered that the use of porous support structures comprising certain materials (e.g., metals such as nickel) can lead to relatively large increases in cell performance. In some embodiments, methods for forming sulfur particles within pores of a porous support structure allow for a desired relationship between the particle size and pore size. The sizes of the pores within the porous support structure and/or the sizes of the particles within the pores can also be tailored such that the resulting electrode is able to withstand the application of an anisotropic force, while maintaining the structural integrity of the electrode.

摘要翻译：本发明涉及在电化学电池中使用包含硫的多孔结构。这样的材料可用于例如在电化学电池中形成一个或多个电极。例如，本文所述的系统和方法可以包括使用包括导电多孔支撑结构的电极和包含基本上包含在支撑结构的孔内的硫（例如，作为活性物质）的多个颗粒。发明人意外地发现，在一些实施例中，多孔支撑结构内的孔的尺寸和/或孔内的颗粒的尺寸可以被调整为使得电解质和硫之间的接触增强，而电极的导电性和结构完整性保持在足够高的水平以允许电池的有效操作。此外，可以选择多孔支撑结构内的孔的尺寸和/或孔内的颗粒的尺寸，使得可以在保持电极中的机械稳定性的同时实现硫与载体材料的任何合适比例。本发明人还意外地发现，使用包含某些材料（例如金属如镍）的多孔支撑结构可导致电池性能的相对较大的增加。在一些实施方案中，用于在多孔载体结构的孔内形成硫颗粒的方法允许颗粒尺寸和孔径之间的所需关系。多孔支撑结构内的孔的尺寸和/或孔内的颗粒的尺寸也可以被调整，使得所得的电极能够承受施加各向异性的力，同时保持电极的结构完整性。
