  • Publication number: 20180090749
    Abstract: The anode and/or the cathode of a lithium-transporting or sodium-transporting electrochemical battery cell or capacitor cell are formed of small (micrometer-size) electrode material particles having one or more channels extending through substantially each electrode particle. The through-channels are formed in the electrode particles as the particles are being formed from precursor materials. Channel-forming fibers are mixed with the electrode precursor materials when the electrode particles are being formed, and the channel forming material is removed from the formed electrode particles to leave through channels in the particles that may subsequently be infiltrated with an electrolyte for the cell.

  • Publication number: 20180034094
    Abstract: Electrodes are formed with a porous layer of particulate electrode material bonded to each of the two major sides of a compatible metal current collector. In one embodiment, opposing electrodes are formed with like lithium-ion battery anode materials or like cathode materials or capacitor materials on both sides of the current collector. In another embodiment, a battery electrode material is applied to one side of a current collector and capacitor material is applied to the other side. In general, the electrodes are formed by combining a suitable grouping of capacitor layers with un-equal numbers of anode and cathode battery layers. One or more pairs of opposing electrodes are assembled to provide a combination of battery and capacitor energy and power properties in a hybrid electrochemical cell. The cells may be formed by stacking or winding rolls of the opposing electrodes with interposed separators.

  • Publication number: 20170309888
    Abstract: Particles of active electrode material for a lithium secondary battery are coated with a precursor material which is either a carbon-based polymer or a metal and oxygen containing compound. The precursor material-coated particles are injected into a gas stream and momentarily exposed to an atmospheric plasma at a predetermined energy level and temperature up to about 3500° C. The plasma treatment converts (i) the carbon polymer to submicron size carbon particles or (ii) the metal compound to metal oxide particles on the surfaces of the particles of electrode material. In preferred embodiments of the invention the plasma treated coated active electrode material particles are carried by the gas stream and deposited onto an electrode material bearing substrate for a lithium battery cell.

  • Publication number: 20170121807
    Abstract: Layers of particles of positive or negative electrode materials for lithium-secondary cells are deposited on porous separator layers or current collector films using atmospheric plasma practices for the deposition of the electrode material particles. Before the deposition step, the non-metallic electrode material particles are coated with smaller particles of an elemental metal. The elemental metal is compatible with the particulate electrode material in the operation of the electrode and the metal particles are partially melted during the atmospheric deposition step to bond the electrode material particles to the substrate and to each other in a porous layer for infiltration with a liquid lithium ion-containing electrolyte. And the metal coating on the particles provides suitable electrical conductivity to the electrode layer during cell operation.

  • Publication number: 20170098817
    Abstract: Improved electrodes for lithium battery cells are made by coating micrometer-size anode or cathode material particles with aggregates of smaller conductive carbon black particles in two mixing steps, using a liquid dispersant in each step for the mixing particles. A first portion of carbon black is vigorously mixed with the electrode particles to coat their surfaces with the smaller carbon black particles. A second portion of carbon black is less vigorously mixed with the initially coated electrode particles to form clusters of carbon black particles at the interfaces of the previously coated electrode particles. This two-step distribution of carbon black particles increases the power capacity of the porous electrode layer bonded to its current collector and increases the life of its battery cell.

  • Publication number: 20170058389
    Abstract: A first atmospheric plasma producing nozzle is used to direct a gas-borne stream of plasma heated and activated particles of lithium battery electrode material for deposition on a surface of lithium cell member, such as a separator or current collector foil. A second atmospheric plasma producing nozzle is used to direct a gas-borne stream of plasma heated and activated metal particles at the same surface area being coated with the stream of electrode material particles. The two plasma streams are combined at the cell member surface to form a layer of electrically-conductive metal-bonded particles of electrode material. The use of multiple atmospheric plasma streams is useful in making thin, efficient, and lower cost electrode structures for lithium batteries.
