Powder Hopper for the Gravity-Driven Feeding of Powdered Electrode Precursor Material Into a Nip of a Dry Electrode Caldender, Corresponding Assembly, and Corresponding Method

Abstract

The invention relates to a powder hopper (101) for the gravity-driven feeding of powdered electrode precursor material (102) into a nip of a dry electrode calendar (2), said powder hopper comprising: a powder feed opening (105) for feeding powdered electrode precursor material (102) into the powder hopper; and a powder outlet opening (106) for metering the powdered electrode precursor material from the powder hopper into a nip, the cross-section of the powder hopper tapering between the powder feed opening and the powder outlet opening, and the powder hopper having a level detection means (103) for detecting the powder level of the powder hopper. The invention also relates to: a corresponding assembly consisting of a powder hopper and a first and a second roller that form a nip; and a method for operating a powder hopper.
