Description

The present invention relates to a battery cell chemical device capable of quickly loading and unloading a battery cell, and particularly to a battery cell chemical device that sandwiches a battery cell in the process of chemical conversion of a pouch-type lithium battery cell and charges and discharges the battery cell.

Lithium battery cells need to be formed before they become commercial products. "Chemical formation" is a state in which power is supplied to the electrodes of a pouch-type lithium battery cell (semi-finished lithium battery cell) to solidify the fluid components of the pouch-type lithium battery cell and store electric energy. To briefly explain the chemical conversion process, first, an unsolidified pouch-type lithium battery cell (pouch-type battery) is fixed to the partition plate of the restraint tray, and then the restraint tray is appropriately pressed by a pressing pressure maintaining mechanism. The pouch-type lithium battery cell is sandwiched between the partition plates, and finally the battery cell is charged and discharged to solidify the battery cell.

TW201943120A1 Patent Document 1 (“Battery cell tray” of TW201943120A1) proposes a conventional battery cell chemical conversion tray. In Patent Document 1, a pouch-type battery is mounted on a partition plate, a through hole is formed as a guide portion on the partition plate, and a guide rod as a connecting member extends through the through hole, whereby the partition plate is a connecting member. It is disclosed that it is arranged so as to slide along. However, when loading and unloading the battery cell, for example, when loading a new pouch-type lithium battery cell, it is necessary to temporarily remove almost all members such as the upper plate, the partition plate, the pressing plate and the transmission device in order to take out the partition plate. It is very inconvenient because there is.

CN209515883U On the other hand, Patent Document 2 (CN209515883U “Constant pressure restraint tray for quickly loading and unloading soft packages”) has been filed in response to the need for quickly loading and unloading battery cells. Patent Document 2 discloses that four fixing plates are provided on a plate for mounting a battery cell, a notch is formed in each fixing plate, and the plate is hung on a connecting rod by the notch. .. It is also disclosed that all plates are connected to each other by four braided strips fastened to the side end faces of the plates with screws. When loading and unloading the battery cell, it is necessary to remove the screws and braided strips before removing the plate from the connecting rod.

Compared to Patent Document 1 in which the guide rod extends through the through hole, the configuration of Patent Document 2 is certainly quicker and more convenient to load and unload the battery cell, but it requires work to remove a plurality of screws. If the position of the notch on the fixing plate shifts or the machining accuracy drops, if one or more of the four contact points of the plate in contact with the connection rod do not contact the connection rod, it will be hooked on the connection rod. The plate is easily rattled. In addition, it is possible for the braided strip to produce debris by tightening, shrinking or pulling, which can easily contaminate equipment or battery cells and become an uneasy factor.

Therefore, there is a demand for a battery cell chemical conversion device that can quickly load and remove battery cells by a simple arrangement, does not contaminate the battery cells, and reduces costs.
