The present disclosure relates to a slot die coating apparatus for coating an electrode active material slurry onto an electrode collector, the slot die coating apparatus including: a coating roller; at least two or more dies; a discharge opening through which the electrode active material slurry is discharged in an opposite direction on which gravity acts; and an air vent installed in the die.

Slot die coating device having air vent

Provided is an electrode for a lithium secondary battery having excellent resistance and output characteristics while achieving high capacity characteristics due to a high active material content.

Electrode for lithium secondary battery

The present disclosure relates to a slot die coating apparatus for coating an electrode active material slurry onto an electrode collector, the slot die coating apparatus including a coating roller, a die comprising a lower discharge opening, through which a first electrode active material slurry is discharged, and an upper die located on the upper side of the lower die and having an upper discharge opening, through which a second electrode active material slurry is discharged, and an upper air vent may be installed in the upper die and a lower air vent may be installed in the lower die.

Provided are a polymer for an organic bottom anti-reflective coating and a bottom anti-reflective coating composition containing the same. More specifically, provided are a polymer for an organic bottom anti-reflective coating capable of relieving reflection of exposure light and irradiation light on a substrate of a photoresist layer applied on the substrate in a lithographic process of manufacturing a semiconductor device, and a bottom anti-reflective coating composition containing the same.

Polymer for organic bottom anti-reflective coating and bottom anti-reflective coatings comprising the same

A method of manufacturing an irregular electrode includes forming a first electrode line by continuously coating a first electrode slurry on a metal sheet, forming at least one second electrode line formed with a dotted line shape including uncoated portions positioned in parallel to the first electrode line by intermittently coating a second electrode slurry on the metal sheet that does not overlap the first electrode line, and forming the irregular electrode by notching the metal sheet with an irregular shape including the second electrode line and the first electrode line except for the uncoated portions of the at least one second electrode line.
