    Abstract: A composite material suitable for an inexpensive cathode material for a lithium-sulfur cell. The composite material is obtained by thermally treating a mixture, wherein the mixture comprises: (A) a fluorinated polymer and (B) carbon in a polymorph containing at least 60% sp2-hybridized carbon atoms; or (A) a fluorinated polymer and (C) a sulfur-containing component; or (A) a fluorinated polymer, (B) carbon in a polymorph containing at least 60% sp2-hybridized carbon atoms, and (C) a sulfur-containing component, in which the proportion of the sum of the proportions by weight of starting components (A) and (B), (A) and (C), or (A), (B), and (C) in the respective mixture prior to the thermal treatment, based on the total weight of the mixture, is 90 to 100% by weight, and wherein the thermal treatment of the mixture containing the above starting components is performed at a temperature of at least 115° C.

    Abstract: Disclosed herein is a process for making an electrode active material, including: (a) forming a mixture, (b) transferring the mixture into saggars, crucibles or open cups, (c) calcining the mixture at a temperature in the range of from 700 to 1000° C., (d) cooling down the resultant electrode active material, (e) applying a robot to take at least two samples of 10 mg to 10 g of every saggar, crucible or open cup to be analyzed, or per defined period of time, respectively, (f) transferring the samples to another robot or to another part of the same robot, where the robot makes an electrode material mix from samples of the same saggar, crucible or open cup, and (g) transferring the electrode material mix to a test unit to perform electrochemical tests, where the robot performs steps (f) to (g) with several samples in parallel.

    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.
