    Abstract: 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.

    Abstract translation: 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。
