no. 1 Embodiment approach

[0040] Figure 4 It is a front view showing the state of pressing the battery cell with the battery pressing device, Figure 5 Is from Figure 4 The side view of the battery pressing device seen in the V-V direction, Image 6 Is from Figure 5 The top view of the battery pressing device as seen in the VI direction.

[0041] Such as Figure 4 ~ Figure 6 As shown, the battery pressing device 50 has a conveying mechanism 60, a pressing mechanism 70 and a connecting mechanism 80. The structure of each mechanism will be described in the order of the conveying mechanism 60, the pressing mechanism 70, and the connecting mechanism 80.

[0042] The transport mechanism 60 transports the battery cells 10 in a state where the short sides of the rectangle are vertically erected. The battery cell 10 is input to the conveying mechanism 60 using another conveying device not shown, for example, a conveying robot that suspends the battery cell 10 in the air and conveys it.

Abstract

The present invention provides a battery pressing device that can press a battery cell in such a way that the battery elements inside the battery cell do not cause lamination deviation, remove gas, air, etc. in the battery element, and instead allow the electrolyte solution to further infiltrate into the battery cell. inside the battery element. The battery pressing device (50) of the present invention has: a roller (72) that presses the battery cell (10) while rotating, and the battery cell (10) has a battery element in which electrodes and separators are stacked in an outer package; and A transport member (60) transports the battery cell (10) at a speed synchronized with the rotational speed of the roller (72) when the battery cell (10) is pressed by the roller (72).

Description

Technical field [0001] The present invention relates to a battery pressing device and a battery pressing method. Background technique [0002] In recent years, battery cells have been used in various products. The battery cell is formed by arranging a battery element in which a positive electrode, a separator, and a negative electrode are laminated in an outer package. The battery element is immersed in the electrolyte in the outer package, and generates electricity through a chemical reaction. [0003] In the process of manufacturing such a battery cell, an electrolyte is injected into the outer package with the battery element arranged in the outer package. The electrolyte solution gradually penetrates from the periphery of the battery element toward the inside. Therefore, air may remain inside the battery element. [0004] In addition, after the electrolyte solution is injected, a part of the electrolyte solution may become a gas due to a chemical reaction, and may accumulate ...
