APPARATUS AND METHOD FOR COATING CURRENT COLLECTORS

摘要

Apparatus and process for continuously coating a web (11) of current collectors with an electrically conductive adhesive material for electrochemical cells and batteries. The apparatus includes: (a) a source of the web of current collector material; (b) a reservoir (26) containing the liquid composition (28); (c) a first rotatable roller (20) having an exterior surface that is at least partially submerged in the liquid composition whereby liquid composition adheres to the exterior surface of the first rotatable roller (24) which comes into contact with the liquid composition; and (d) a second rotatable roller that is positioned adjacent to the first rotatable roller and wherein an exterior surface of the second rotatable roller and an exterior surface of the first rotatable roller defines a nip (21) through which the web of current collector material traverses.
