Abstract: A nonaqueous electrolyte secondary battery includes: an electrode body; a nonaqueous electrolyte liquid; a metal-made exterior package receiving the electrode body and the nonaqueous electrolyte liquid; and a pressing member provided between the electrode body and the exterior package. An outer circumference surface of the electrode body includes an exposing section to which a surface of a negative electrode collector forming the negative electrode is exposed. In addition, the pressing member expands when absorbing the nonaqueous electrolyte liquid and presses the exposing section of the electrode body to an inner surface of the exterior package.

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 electrode plate has a band-shaped core, and an active material layer formed on both surfaces of the core, and a current collector lead is connected to an exposed part at which the core is exposed. The exposed part is placed on the longitudinal direction portion of the core, and an identification display part that can specify the history of the manufacturing process is formed at a position different from the current collector lead in the exposed part. In the core, the active material layer is placed at a position on the opposite side to the identification display part in the core thickness direction.

Abstract: This non-aqueous electrolyte secondary battery has an electrode body comprising a positive electrode and a negative electrode which are wound around while sandwiching a separator therebetween, and housed in a cylindrical housing member. The positive electrode has a positive electrode collector and a positive electrode active substance layer extending above the positive electrode collector. The negative electrode has a negative electrode collector, a negative electrode active substance layer extending above the negative electrode collector, and a negative electrode lead connected to the negative electrode collector. The negative electrode lead is disposed more toward the wound core of the electrode body than the end portion of the negative electrode active substance layer and the end portion of the positive electrode active substance layer.
