Technical Field

[0001] The utility model relates to the technical field of lithium strip rolling, in particular to a lithium strip rolling lubrication device. Background Art

[0002] With the rapid development of new energy technologies, people's demand for the energy density of high-energy-density energy storage devices is increasing. Lithium metal, as a negative electrode material and pre-lithiation material, can greatly improve the energy density of existing lithium-ion batteries. Lithium metal usually exists in block or powder form. It can be processed into the required thin sheets or strips through rolling, which is convenient for the subsequent manufacture of batteries or other electrochemical devices. However, lithium metal has low strength and high viscosity, and is extremely difficult to process. Therefore, during the rolling process of lithium strips, rolling oil needs to be continuously added for lubrication.

[0003] The lithium strip rolling lubrication device can provide lubrication during the lithium strip rolling process to promote a smooth rolling process, but it still has certain problems: 1) The traditional lubrication device cannot accurately control the amount of rolling oil added and the thickness of the oil film. The high activity of lithium metal and the strong adsorption of oil make the lithium metal processing process extremely oil-intensive, and excessive oil load will cause slippage between the lithium strip and the rollers; 2) The traditional lubrication device cannot monitor the oil film thickness; therefore, in view of the above situation, there is an urgent need to develop a lithium strip rolling lubrication device to overcome the shortcomings in current practical applications and meet current needs.

Four sliding shafts 344 are horizontally welded in groups of two at both ends of the L-shaped mounting seat 341. The L-shaped mounting seat 341 is detachably connected to the mounting frame 310 through the sliding shaft 344.
