Abstract: Electrodes are formed by, as a dry method, alternately applying electrode active material and electrolyte particles as thin-film layers. Furthermore, the films are formed wholly or partially by employing an aerosol deposition method. Moreover, high-density layers can be formed and adhesion is improved by, as a wet method, impactfully and alternately colliding, with a target object, slurry made primarily from an electrode active material and solvent and a slurry made primarily from electrolyte particles and a solvent, adhering same in thin films and layering same. A slurry made primarily from a conductivity aid and a solvent is independently prepared, and a small quantity thereof is applied diffusely at a desired position. Moreover, by using no binder or keeping binder content low, residual carbon can be eliminated or kept low so as to improve battery performance.

Abstract: [Problem] To lower electrical resistance by increasing the interfacial surface area and the adhesion between a current collector and an active material or an electrolyte, or between the active material and the electrolyte in an all-solid-state battery. In addition, to improve battery performance by eliminating or minimizing residual carbon originating from a binder. [Solution] According to the present invention, a slurry, composed of an electrode active material and a solvent, and a slurry, composed of electrolyte particles and a solvent, can be impacted against a target and thereby attached thereto to form a high-density layer and improve adhesion. Moreover, residual carbon is eliminated or minimized by eliminating or minimizing the content of binders, thereby improving battery performance.

Abstract: A preliminary container upstream of a slurry container, a tube or pipe of a compressed air discharge line from the slurry container is inserted into the preliminary container, so that, even if a slurry flows back, the slurry is retained in the preliminary container and the slurry is prevented from flowing back upstream of the preliminary container. In addition, minute droplets are prevented from flowing back upstream, by using a protector, or an air-permeable screen.

Abstract: Provided is an LED production method that can produce a great number of high-quality LEDs at low production cost. A binder-rich layer is formed on LEDs to increase the adhesiveness between the LEDs and a substrate; a phosphor layer or phosphor-rich layer is formed over the layer with a mask put on the layer; and the phosphor or a mixture of the phosphor and binder on the mask is recovered and reused.

Abstract: [PROBLEM TO BE SOLVED] To provide a method and apparatus for applying a coating material that reacts at ordinary temperatures and increases in viscosity with lapse of time or a coating material that is difficult to handle, such as an unstable slurry in which sedimentation occurs at high rate, to a high-value-added object to be coated.[SOLUTION] Before at least applying coating material to an object to be coated, the coating amount is automatically measured using a highly-accurate measuring device set in an atmosphere that does not substantially affect the measurement to control the coating amount during production. Therefore, high-quality products can be mass-produced with a low production cost.

Abstract: A high-density layer can be formed and adherence increased by causing a slurry formed primarily from an electrode active material and a solvent and a slurry formed primarily from electrolyte particles and the solvent to alternately collide with a subject material with an impact force and to adhere and be layered thereon in thin film. A slurry formed primarily from a conductive additive and the solvent is separately created and is coated in a dispersed manner in a small quantity at a desired position. Carbon residue is eliminated or greatly reduced and battery performance improved by eliminating a binder or greatly reducing the binder content.

Abstract: [Problem] Upon application or film formation of a particulate matter to/on an object, the particulate matter moving with a speed is heated in a time duration from a suction port for particulate matter to the object, thereby softening or melting at least some of the particulate matter when the particulate matter is applied to the object.
[Solution] A particulate matter is heated by means of induction heating or laser in a time duration from a suction port for particulate matter to an object, so that at least some of the particulate matter is softened or melted at a relatively low temperature on the object in synergy with the collision energy of the particulate matter with the object, thereby enabling the application or film formation of the particulate matter.
