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： A hermetic sample holder for use in performing microanalysis of a sample under a controlled atmosphere environment. The sample holder comprises a sample holder body with a sample cavity to receive the sample and a cover movably mounted to the holder body between an open position to allow access to the cavity and a closed position to seal the cavity. The cover is secured in and released from the closed position at least in part by a pressure differential between the cavity and the ambient atmosphere. The cover may be biased toward the open position. The cover may be pivotally mounted about an axis that is perpendicular to a sealing surface of the cover and/or movable in a direction along the pivot axis. A valve may be provided to allow direct evacuation of the cavity to create a pressure differential. An adjustable clamp may be located in the cavity to secure the sample.
