Description

Technical Field

[0001] The utility model relates to the technical field of sodium ion battery pole pieces, in particular to a tablet pressing device for sodium ion battery pole pieces. Background Art

[0002] Sodium-ion batteries stand out among the current new energy storage devices because of their high safety, strong thermal stability and excellent electrochemical performance, and are expected to partially replace or supplement lithium-ion batteries. In the preparation process of sodium-ion battery pole pieces, the battery pole pieces need to be coated, and qualified positive / negative pole pieces are prepared after drying and pressing.

[0003] In order to improve the energy density and conductivity of the sodium ion battery pole pieces, the sodium ion battery pole pieces need to be pressed when necessary, so a pressing device is needed.

[0004] When the existing pressing device is used to press the sodium ion battery pole pieces, the sodium ion battery pole pieces are usually fixed manually and then pressed manually. This method is not only time-consuming and laborious, but also very easy to be offset during the pressing process. The offset sodium ion battery pole pieces will affect the subsequent pressing process. In addition, the manual fixing method is very easy to apply excessive pressure to the sodium ion battery pole pieces due to excessive manual strength, thereby causing damage to the sodium ion battery pole pieces. To address this problem, we propose a pressing device for sodium ion battery pole pieces. Utility Model Content
