摘要： The present invention discloses a method of synthesizing transition metal nitride by using supercritical ammonia. Transition metal nitride such as vanadium nitride, molybdenum nitride, titanium nitride, nickel nitride, neodymium nitride, iron nitride, etc. can be synthesized in supercritical ammonia with reducing mineralizers such as potassium, sodium, lithium, magnesium, calcium, and aluminum. Since supercritical ammonia has characteristics of both gas and liquid, it can over complicated fine structure or fine particles. The new method is suitable for forming a protective coating on complicated structure or forming micro- to nano-sized particles.

摘要： The present invention provides a resin composition comprising: 1 to 20 parts by weight of a reinforcing fiber; 0.2 to 5 parts by weight of an anti-settling agent; 20 to 40 parts by weight of an epoxy resin; 0.1 to 3 parts by weight of a curing agent; and 50 to 75 parts by weight of a high dielectric constant filler. The present invention further provides a dielectric layer produced from the resin composition and a capacitor comprising the dielectric layer. In the dielectric layer made from the resin composition provided by the present invention, the fibers can be evenly dispersed and can enhance the mechanical strength of the resin composition, and cooperate with the epoxy resin to bring excellent toughness. Therefore, the mechanical strength of the produced dielectric layer can be remarkably improved, and its fragility can be effectively overcome when the dielectric layer is used in the PCB double-side etching process.

摘要： The disclosure describes an improved electrode with high voltage standoff characteristics and improved graphene-based materials and methods of making them for use therein. A graphene-based thin film material is described that may be applied or transferred to a current collector to create the improved electrode. The thin film comprises high aspect ratio graphene platelets applied to the surface of a current collector or other substrate in a known ratio to a film binder material. The film is produced with a desired layer thickness and graphene-to-binder ratio to produce a desired voltage standoff for the electrode. The film may include additional materials to achieve the desired dielectric and mechanical characteristics for the application, such as ferroelectric ceramic nanorods with a high aspect ratio and high dielectric constant and/or graphene sheets. The thin film dielectric materials may have applications in more than just the anode of the graphene electrolytic capacitor, but find application as a dielectric layer in other electrical applications, such as batteries, electrode sensor arrays, and nano-scale solid-state electronics.

摘要： A novel hybrid lithium-ion anode material based on coaxially coated Si shells on vertically aligned carbon nanofiber (CNF) arrays. The unique cup-stacking graphitic microstructure makes the bare vertically aligned CNF array an effective Li+ intercalation medium. Highly reversible Li+ intercalation and extraction were observed at high power rates. More importantly, the highly conductive and mechanically stable CNF core optionally supports a coaxially coated amorphous Si shell which has much higher theoretical specific capacity by forming fully lithiated alloy. Addition of surface effect dominant sites in close proximity to the intercalation medium results in a hybrid device that includes advantages of both batteries and capacitors.

摘要： The present invention is directed to a method of manufacture of metal or alloy powders that uses liquid phase reduction of a metal halide, or a mixture of metal halides, to produce a metal particle coated in salts produced as a reaction byproduct. The reaction conditions can be chosen to select a range of metal particle sizes, and the salt coating prevents oxidation (or reaction with other atmospheric gases) and permits a range of applications hitherto difficult to achieve using metal powders.

摘要： A solid electrolytic capacitor that contains an anode body formed from an electrically conductive powder and a dielectric coating located over and/or within the anode body is provided. The powder may have a high specific charge and in turn a relative dense packing configuration. Despite being formed from such a powder, a manganese precursor solution can be readily impregnated into the pores of the anode. This is accomplished, in part, through the use of a dispersant in the precursor solution that helps minimize the likelihood that the manganese oxide precursor will form droplets upon contacting the surface of the dielectric. Instead, the precursor solution can be better dispersed so that the resulting manganese oxide has a “film-like” configuration and coats at least a portion of the anode in a substantially uniform manner.
