Problems solved by technology

For this reason, the flow velocities at the discharge units 16a, 16b, 16c corresponding to the backing plates 14a, 14b, 14c separated by the non-coating portion 15 are different from each other (see image 3 Graph of ), therefore, different amounts of fluid are applied by the discharge units 16a, 16b, 16c, which will make the uniformity of the final product worse

Abstract

Disclosed is a slot coater, which includes a feeding unit having a passage through which a coating fluid flows in, a manifold for accommodating the coating fluid supplied through the feeding unit, a discharge unit communicating with the manifold to discharge the coating fluid accommodated in the manifold, a plurality of shim plates arranged at regular intervals in a length direction of the manifold, and a temperature control unit for generating a temperature difference between a shim plate located relatively closer to the feeding unit and a shim plate located respectively farther from the feeding unit.

Description

technical field [0001] The present invention relates to a slot coater, and more particularly, to a slot coater configured to control a discharge flow rate of a coating liquid to achieve uniform coating. [0002] This application claims Korean Patent Application No. 10-2015-0132579 filed with the Korean Intellectual Property Office on September 18, 2015 and Korean Patent Application No. 10-2014-0143576 filed with the Korean Intellectual Property Office on October 22, 2014 , and the priority benefit of Korean Patent Application No. 10-2014-0143579 filed with the Korean Intellectual Property Office on October 22, 2014, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] In general, a secondary battery includes a battery case and an electrode assembly housed in the battery case together with an electrolyte. [0004] The electrode assembly has a structure in which positive electrodes, separators and negative electrodes are a...
