A method of manufacturing a formed body for an electrode including: a step of jetting an electrode material containing an electrode active material from an outlet toward a surface Fof a first support while relatively moving the outlet jetting the electrode material and the first support in a plane direction of the first support, in which in the step, a contact member having a contact surface Fthat is brought into contact with the electrode material is used, and in a case where a wall friction angle between the contact surface Fof the contact member and the electrode material is denoted by θ1, and a wall friction angle between the surface Fof the first support and the electrode material is denoted by θ2, a relationship (1) 1°≤θ1<15° and a relationship (2) 15°≤θ2 are satisfied.

Method of manufacturing formed body for electrode

The present disclosure provides a method of manufacturing a formed body for an electrode including: a step of preparing an electrode material containing an electrode active material; a step of supplying the electrode material onto the support; and a step of pressurizing the electrode material on the support by sandwiching the support and the electrode material between a first roll that is brought into contact with the electrode material and a second roll that is brought into contact with the support, in which a temperature T1 of the first roll and a temperature T2 of the second roll satisfy a relationship T1>T2.

A method of manufacturing a formed body for an electrode includes a first step of dropping an electrode material containing an electrode active material into a gap between a pair of transport belts and introducing the electrode material between transport surfaces of the pair of transport belts; a second step of belt-transporting and pressurizing the introduced electrode material with the pair of transport belts; and a third step of transferring the electrode material after the belt transporting and the pressurization, on a deposition belt, in which a transport direction in a transport, passage through which the electrode material is transported, of the deposition belt intersects a transport direction in a transport passage, through which the electrode material is transported, of the pair of transport belts.

The present disclosure provides a method of manufacturing a formed body for an electrode including: a step of preparing an electrode material containing an electrode active material; a step of forming at least two projecting portions containing the electrode material and placed side by side on a support in a width direction of the support by supplying the electrode material onto the support; and a step of leveling the projecting portions on the support.

The present disclosure provides a method of manufacturing a formed body for an electrode comprising in order: a step of preparing an electrode material containing an electrode active material; a step of supplying the electrode material to a forming mold which has a frame-shaped side wall portion defining a space portion accommodating the electrode material and has a first support placed on a bottom surface of the forming mold; a step of forming the electrode material along an internal shape of the forming mold; and a step of taking out the electrode material from the forming mold.

A method of manufacturing a formed body for an electrode includes: preparing an electrode material; placing a shape retaining member having an rectangular tubular shape with one opening portion L thereof facing down, and supplying the electrode material into the shape retaining member from the other opening portion M thereof; and discharging the electrode material onto a support from the opening portion L while relatively moving the opening portion L and the support, to form a film, a bulk density Dof the electrode material in the first step and a bulk density Dof the electrode material at the opening portion L satisfying a relationship of D/D=1.1 to 30, and a width Tof the opening portion L in a short side direction and a distance Tbetween the end portion X of the opening portion L and the support satisfying a relationship of width T&#x3e;distance T.

A web joining apparatus and related method. The apparatus includes a turret arm which supports an old roll and a new roll around which band-state flexible support bodies are wound, a front pasting drum including a holding device holding the tip end of the band-state flexible support body of the new roll and a cutting drum provided with a cutting member with substantially the same length as the width of the band-state flexible support body. A projection amount is set so that only a single sheet of the band-state flexible support body can be cut off. The flexible support body of the old roll is cut off and the tail end of the flexible support body of the old roll and the tip end of the flexible support body of the new roll are joined as the band-state flexible support body is conveyed.
