Description

Apparatus and system for impregnating separator with electrolyte}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for impregnating an electrolyte solution in a separator, and more particularly, to an electrolyte solution impregnation device and system for improving the impregnation property of an electrolyte solution by a simple device.

Recently, as the demand for portable electronic products such as notebooks, video cameras, portable telephones, etc. is rapidly increased, and development of electric vehicles, energy storage batteries, robots, satellites, and the like is in earnest, high-performance secondary batteries capable of repeatedly charging and discharging are possible. There is an active research on.

Commercially available secondary batteries include nickel cadmium batteries, nickel hydride batteries, nickel zinc batteries, and lithium secondary batteries. Among them, lithium secondary batteries have almost no memory effect compared to nickel-based secondary batteries, and thus are free of charge and discharge. The self-discharge rate is very low and the energy density is high.

On the other hand, as the trend of higher capacity of the secondary battery and the unit size of the electrode plate of the secondary battery increases, the importance of the impregnation of the electrolyte is increasing. The manufacturing process of the secondary battery generally includes a process in which a liquid electrolyte, that is, an electrolyte solution, is injected while the electrode assembly is accommodated in the battery case, and the battery case is sealed.

Here, the electrolyte solution is permeated by capillary force between the positive electrode plate, the negative electrode plate, and the separator constituting the electrode assembly. By the way, the positive electrode plate, the negative electrode plate and the separator is a material having a high hydrophobicity, the electrolyte is a hydrophilic material, it takes a considerable time to impregnate the electrode assembly by the electrolyte solution, and the process conditions are also difficult.

If the impregnation (wetting) of the electrolyte becomes incomplete, the charge and discharge characteristics of the battery, such as the capacity of the secondary battery, as well as the deterioration of the electrode state can be intensified. As a result, there is a fear that the electrode reaction is concentrated locally, which causes a serious problem in the safety of the battery. In addition, when the size of the electrode plate is increased, the time required for impregnation of the electrolyte is increased, so there is a problem in that the productivity of the secondary battery is lowered. In addition, the poor impregnation of the electrolyte has a problem that can accelerate the degeneration of the electrode to shorten the life of the battery, although the other electrode state is good.
