Abstract
Official abstract text for this publication.
A battery pressing device includes a roller and a transport device. The roller is configured to rotate at a rotational speed when pressing a battery cell in which is disposed a battery element having electrodes and separators layered inside an external packaging. The transport mechanism is configured to transport the battery cell at a transport speed that is synchronized with the rotational speed of the roller when the battery cell is being pressed by the roller.
First claim
Opening claim text (preview).
The invention claimed is: 1. A battery pressing device comprising: a pair of rollers configured to rotate at a rotational speed around a vertical rotating shaft when pressing a battery cell in which is disposed a battery element having electrodes and separators layered inside an external packaging; a driving unit configured to rotate the pair of rollers; and a transport mechanism configured to transport the battery cell in a vertically standing state at a transport speed that-matches a tangential speed of the pair of rollers, wherein the battery cell is pressed by sandwiching the battery cell in the vertically standing state between the pair of rollers. 2. The battery pressing device according to claim 1 , wherein the transport mechanism and the pair of rollers are mechanically synchronized. 3. The battery pressing device according to claim 1 , wherein the rotational speed of the pair of rollers is synchronized with the transport speed of the battery cell. 4. The battery pressing device according to claim 3 , wherein the transport mechanism is configured to transport the battery cell by holding an edge of the external packaging without sandwiching the battery element. 5. A battery pressing method for pressing a battery cell in which is disposed a battery element having electrodes and separators layered in an external packaging, the battery pressing method comprising: pressing the battery cell by sandwiching the battery cell in a vertically standing state between a pair of rollers which rotate around a vertical rotating shaft at a rotational speed; and transporting the battery cell in the vertically standing state by a transport mechanism at a speed that matches a tangential speed of the pair of rollers. 6. The battery pressing method according to claim 5 , further comprising mechanically synchronizing the transport mechanism and the pair of rollers.
