Abstract: This method for producing a positive electrode slurry comprises: a step wherein an aqueous solution, in which a smectite is dissolved, is mixed with a solvent containing N-methyl-2-pyrrolidone (NMP), thereby preparing an aqueous smectite-NMP solution; a step wherein the aqueous smectite-NMP solution is subjected to thermal dehydration, thereby obtaining a smectite-containing solid content lump; and a step wherein the smectite-containing solid content lump, a positive electrode active material and the solvent containing N-methyl-2-pyrrolidone (NMP) are mixed with each other, thereby preparing a slurry.

Abstract: A double-sided coating device includes: a conveying mechanism for a base material that includes a first surface and a second surface; a first die that applies a first coating material onto the first surface; and a second die that applies a second coating material onto the second surface. The conveying mechanism includes: a roll that conveys the base material, in which the position at which the base material separates from the circumferential surface is higher than a target coating height of the base material; and a drawing section that draws the base material such as to bring the base material closer to the target coating height.

Abstract: An intermittent valve device includes: an intermittent valve capable of switching between a first state in which a coating material is supplied to a die that applies the coating material onto a material to be coated and a second state in which the supply of the coating material is stopped; and a drive unit that switches the first state and the second state of the intermittent valve. The drive unit includes a cam that rotates in one direction with a circumferential surface of the cam connected to the intermittent valve. The cam includes, on the circumferential surface, a first shape part that places the intermittent valve in the first state, and a second shape part that places the intermittent valve in the second state.

Abstract: An intermittent coating device includes a die used to apply a coating material onto a material to be coated, and a first intermittent valve and a second intermittent valve capable of switching between a first state in which the coating material is supplied to the die and a second state in which the supply of the coating material is stopped. The first intermittent valve and the second intermittent valve have different timings of switching between the first state and the second state.

Abstract: This intermittent coating device is provided with a die which applies paint to a workpiece, and a first intermittent valve and a second intermittent valve which can switch between a first state in which paint is provided to the die and a second state in which provision of paint is stopped. The first intermittent valve and the second intermittent valve have mutually different timing for switching between the first state and the second state.
