Process for producing nano graphene reinforced composite particles for lithium battery electrodes

A process for producing solid nanocomposite particles for lithium metal or lithium ion battery electrode applications is provided. In one preferred embodiment, the process comprises: (A) Preparing an electrode active material in a form of fine particles, rods, wires, fibers, or tubes with a dimension smaller than 1 μm; (B) Preparing separated or isolated nano graphene platelets with a thickness less than 50 nm; (C) Dispersing the nano graphene platelets and the electrode active material in a precursor fluid medium to form a suspension wherein the fluid medium contains a precursor matrix material dispersed or dissolved therein; and (D) Converting the suspension to the solid nanocomposite particles, wherein the precursor matrix material is converted into a protective matrix material reinforced by the nano graphene platelets and the electrode active material is substantially dispersed in the protective matrix material. For a lithium ion battery anode application, the matrix material is preferably amorphous carbon, polymeric carbon, or meso-phase carbon. Such solid nanocomposite particles provide a high anode capacity and good cycling stability. For a cathode application, the resulting lithium metal or lithium ion battery exhibits an exceptionally high cycle life.

Broadband power combining device using antipodal finline structure

A broadband power combining device includes an input port, an input waveguide section, a center waveguide section formed by stacked wedge-shaped trays, an output waveguide section, and an output port. Each tray is formed of a wedge-shaped metal carrier, an input antipodal finline structure, one or more active elements, an output antipodal finline structure, and attendant biasing circuitry. The wedge-shaped metal carriers have a predetermined wedge angle and predetermined cavities. The inside and outside surfaces of the metal carriers and surfaces of the cavity all have cylindrical curvatures. When the trays are assembled together, a cylinder is formed defining a coaxial waveguide opening inside. The antipodal finline structures form input and output arrays. An incident EM wave is passed through the input port and the input waveguide section, distributed by the input antipodal finline array to the active elements, combined again by the output antipodal finlines array, then passed to the output waveguide section and output port. A hermetic sealing scheme, a scheme for improving the power combining efficiency and thermal management scheme are also disclosed. The broadband power combining device operates with multi-octave bandwidth and is easy to manufacture, well-managed thermally, and highly efficient in power combining.

Method for sending and detecting downlink control information

The invention provides a method for sending and detecting downlink control information, a base station carries the downlink control information in a physical downlink control signal channel, the physical downlink control signal channel is sent through a component carrier, wherein the base station carries the first type of downlink control information on the main component carrier and carries the third type of downlink control information on the first component carrier, the first type of downlink control information carries uplink and / or downlink scheduling information and / or uplink power control information of the component carrier in which the first type of downlink control information is located, the second type of downlink control information carries uplink and / or downlink scheduling information of one or a plurality of component carriers, and the third type of downlink control information carries indication information of the second type of downlink control information. A terminal detects the first type of downlink control information on the main component carrier and detects the third type of downlink control information on the first component carrier. The method has better scheduling flexibility, compatibility and error code performance, lower blind detection times and lower signaling cost.
