  • Publication number: 20220302438
    Abstract: The present disclosure relates generally to an electrode produced with a non-toxic solvent, resulting in a homogeneous mixture with uniform distributions of a conductive additive and a binder. Electrodes produced according to the present disclosure feature narrow binder particle size distribution, which distinguishes such electrodes from typical electrodes produced via a N-Methyl-Pyrrolidone (NMP) process. The resulting microstructure promotes the flow of current through the electrode and has an improved cycling stability due, in part, to the binder's and the conductive additive's ability to bind with the active material particles used in the fabrication of the electrode.

  • Patent number: 10153482
    Abstract: The present invention relates to a method for manufacturing slurry for coating of electrodes for use in lithium ion batteries, wherein the method comprises mixing active materials with a binder into a binder solution, and adding an organic carbonate to the binder solution to generate the slurry. The present invention also relates to a method for manufacturing electrodes for a lithium battery cell, wherein the method comprises mixing active materials with a binder into a binder solution, adding an organic carbonate to the binder solution to generate slurry, wherein the above adding step is carried out at temperature above melting temperature of the organic carbonate, coating electrode material with the slurry, drying the coating on the electrode material by drying the organic carbonate, and surface treatment of the slurry so that the electrode is prepared for use in a lithium ion battery cell.

  • Patent number: 9173814
    Abstract: The present invention relates to a container for liquids, a method of filling it and the use of the container according to the invention for holding and storing radioactive substances. The container for a liquid comprises a cavity for holding the liquid, the cavity being bounded by walls (1) at the sides and at the bottom, an opening for filling the cavity with the liquid, a closure for closing off the cavity, the closure having a piercing region for inserting a cannula into the cavity, a bottom casing (20) which surrounds the walls of the cavity in the standing area, a top casing (10) which surrounds the pierceable closure with the exception of the piercing region, and a film (30) which extends from the top casing to the bottom casing and surrounds those areas of the walls of the cavity which are not already surrounded by the top casing or bottom casing.

  • Patent number: 6202855
    Abstract: An invention provides a process for the selection from a particulate pharmaceutical product of particles of a preselected size, said process comprising (i) obtaining a substantially homogeneous suspension of said particulate pharmaceutical product in a fluid suspension medium which is immiscible with said product and is of different density to said product, (ii) carrying out a size selection procedure to set an effective lower or upper size limit on the articles in the final particulate product, wherein step (ii) comprises either allowing said suspension to settle for a predetermined period, separating said suspension into a first and second component in a predetermined volume ratio, said first component deriving from an upper layer of said suspension and said second component deriving from a lower layer of said suspension, adding further suspension medium to said first component where said medium is more dense than the pharmaceutical product or to said second component where said medium is less dense than th
