  • Patent number: 10601027
    Abstract: A method of making an electrode includes the step of dispersing an active electrode material and a conductive additive in a solvent to create a mixed dispersion. The solvent has a surface tension less than 40 mN/m and an ozone forming potential of no more than 1.5 lbs. ozone/lb. solvent. A surface of a current collector is treated to raise the surface energy of the surface to at least the surface tension of the solvent or the mixed dispersion. The dispersed active electrode material and conductive additive are deposited on the current collector. The coated surface is heated to remove solvent from the coating.

  • Publication number: 20180323422
    Abstract: A method of making an electrode includes the step of mixing active material particles, radiation curable resin precursors, and electrically conductive particles to create an electrode precursor mixture. The electrode precursor mixture is electrostatically sprayed onto a current collector to provide an electrode preform. The electrode preform is heated and calendered to melt the resin precursor such that the resin precursor surrounds the active particles and electrically conductive particles. Radiation is applied to the electrode preform sufficient to cure the radiation curable resin precursors into resin.

  • Patent number: 9689822
    Abstract: A system and a method for characterizing a dielectric material are provided. The system and method generally include applying an excitation signal to electrodes on opposing sides of the dielectric material to evaluate a property of the dielectric material. The method can further include measuring the capacitive impedance across the dielectric material, and determining a variation in the capacitive impedance with respect to either or both of a time domain and a frequency domain. The measured property can include pore size and surface imperfections. The method can still further include modifying a processing parameter as the dielectric material is formed in response to the detected variations in the capacitive impedance, which can correspond to a non-uniformity in the dielectric material.

  • Patent number: 9337470
    Abstract: A method of drying casted slurries that includes calculating drying conditions from an experimental model for a cast slurry and forming a cast film. An infrared heating probe is positioned on one side of the casted slurry and a thermal probe is positioned on an opposing side of the casted slurry. The infrared heating probe may control the temperature of the casted slurry during drying. The casted slurry may be observed with an optical microscope, while applying the drying conditions from the experimental model. Observing the casted slurry includes detecting the incidence of micro-structural changes in the casted slurry during drying to determine if the drying conditions from the experimental model are optimal.

  • Patent number: 8834829
    Abstract: The invention provides a method of making a battery anode in which a quantity of graphite powder is provided. The temperature of the graphite powder is raised from a starting temperature to a first temperature between 1000 and 2000° C. during a first heating period. The graphite powder is then cooled to a final temperature during a cool down period. The graphite powder is contacted with a forming gas during at least one of the first heating period and the cool down period. The forming gas includes H2 and an inert gas.

  • Publication number: 20140178602
    Abstract: A method of making a cathode for a battery includes the steps of depositing a precursor cathode film having a first crystallinity profile. The precursor cathode film is annealed by irradiating the precursor cathode film with from 1 to 100 photonic pulses having a wavelength of from 200 nm to 1600 nm, a pulse duration of from 0.01 ?s and 5000 ?s and a pulse frequency of from 1 nHz to 100 Hz. The photonic pulses are continued until the precursor cathode film has recrystallized from the first crystallinity profile to a second crystallinity profile.

  • Patent number: 7620980
    Abstract: A secure data broker has been developed, which provides a restricted message based data exchange between a client application and a secured information resource by allowing registered or verified messages to be brokered across a security barrier. In some configurations, both requests and responses are validated and brokered across the security barrier. In other configuration, either requests or responses are validated. To support validation, messages are formatted in accordance with a predefined message specification for at least part of a transaction path between a client application and an information resource accessed by the client application.

  • Patent number: 7325128
    Abstract: A security architecture has been developed in which a single sign-on is provided for multiple information resources. Rather than specifying a single authentication scheme for all information resources, the security architecture associates trust-level requirements with information resources. Authentication schemes (e.g., those based on passwords, certificates, biometric techniques, smart cards, etc.) are employed depending on the trust-level requirement(s) of an information resource (or information resources) to be accessed. Once credentials have been obtained for an entity and the entity has been authenticated to a given trust level, access is granted, without the need for further credentials and authentication, to information resources for which the authenticated trust level is sufficient.
