Patent number: 10319988Abstract: 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.Type: GrantFiled: June 15, 2017Date of Patent: June 11, 2019Assignee: Sion Power CorporationInventors: Tracy Earl Kelley, Savannah V. Burnside-Joubert, Ruediger Schmidt, Holger Schneider, Klaus Leitner, Joern Kulisch

Patent number: 9577267Abstract: 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).Type: GrantFiled: June 18, 2015Date of Patent: February 21, 2017Assignees: Sion Power Corporation, BASF SEInventors: Chariclea Scordilis-Kelley, Ruediger Schmidt, Holger Schneider, Tracy Earl Kelley, Savannah V.

Patent number: 9419274Abstract: 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.Type: GrantFiled: October 30, 2014Date of Patent: August 16, 2016Assignee: Sion Power CorporationInventors: William F. Wilkening, Christopher T. S. Campbell, Savannah V. Burnside-Joubert
