The present application provides a kind of lithium ion battery electrode coating with flow uniformity gasket and its coating method, to solve the problem of poor consistency of coating caused by uneven distribution of slurry flow rate in traditional slot coating process.The core structure is flow uniformity gasket, and the flow uniformity gasket body wall surface is symmetrically provided with integrated flow uniformity structure, the flow uniformity structure includes the wall surface that is narrowed upstream and expanded downstream along the slurry incoming flow direction.Through the above structure, the flow uniformity gasket can effectively suppress the Poiseuille effect of "low on both sides, high in the middle" in traditional slot coating, and realize the uniform distribution of slurry flow rate at slot outlet.The slot coating method using the flow uniformity gasket can ensure the uniformity and consistency of film coating thickness while avoiding the increase of additional pipeline load;Its efficient, convenient, low energy consumption and low cost characteristics can significantly improve the coating yield and economic benefit.
