Definitions
- the present invention relates to a powder conveying system and a powder conveying method, and more particularly, when the powder showing the powder form is conveyed along the conveying line, it smoothly passes the precisely metered powder in a vertical pipe installed vertically among the conveying lines.
- it relates to a powder conveying system and a powder conveying method for preventing the powder from remaining or stagnating in the vertical pipe.
- aqueous electrolyte-based lithium secondary batteries and capacitors that can be applied to fields requiring high output characteristics are attracting attention.
- Such an electrochemical device generally includes a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode.
- the positive electrode and the negative electrode are generally applied to the surface of the current collector by applying an electrode active material slurry containing a solvent for dissolving the polymer binder for uniform mixing of the electrode active material, the polymer binder, and the electrode active material to form the electrode active material layer. manufactured.
- the electrode active material slurry may further include a conductive material to improve electrical conductivity of the electrode. Meanwhile, in order to form an excellent electrode, a dispersing material for uniformly dispersing at least one of the electrode active material and the conductive material may be further included. This is because the shape of the electrode is changed according to the degree of dispersion of the electrode active material and the conductive material, and thus the performance of the battery is also changed.
- An object of the present invention is to solve the problems of the prior art, and when the powder representing the powder form is transported along the transport line, the precisely metered powder passes smoothly in a vertical pipe installed vertically among the transport lines, while the powder To provide a powder conveying system and a powder conveying method to prevent remaining or stagnation in the vertical pipe.
