Title
(DE) EX-SITU-HERSTELLUNG EINER LITHIUMANODENSCHUTZSCHICHT

Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer Anode für eine Lithiumzelle und/oder einer Lithiumzelle sowie derartige Anoden und Lithiumzellen. Um die Lebensdauer der Lithiumzelle zu verlängern und gezielt eine erste, Elektrolytzersetzungsprodukte umfassende, Schutzschicht (2) auf einer, metallisches Lithium umfassenden Anode (1) auszubilden, wird ex situ, also vor dem Zusammenfügen der herzustellenden Lithiumzelle, ein erster Elektrolyt auf die Anode (1) aufgebracht. In einem nachfolgenden Verfahrensschritt kann zur Stabilisierung der ersten Schutzschicht (2) eine zweite Schutzschicht (3) aufgebracht werden.
(EN)
The present invention relates to a process for producing an anode for a lithium cell and/or a lithium cell and also to such anodes and lithium cells. In order to increase the service life of the lithium cell, and to specifically form a first protective layer (2) comprising electrolyte decomposition products on an anode (1) comprising metallic lithium, a first electrolyte is applied to the anode (1) ex situ, i.e. before the lithium cell to be produced is assembled. In a subsequent process step, a second protective layer (3) can be applied to stabilize the first protective layer (2).
(FR)
L'invention concerne un procédé pour produire une anode pour pile au lithium et/ou une pile au lithium ainsi que des anodes et des piles au lithium. L'invention vise à prolonger la durée de vie de la pile au lithium et à réaliser une première couche de protection (2), comprenant des produits de décomposition électrolytique, sur une anode (1) comprenant du lithium métallique. A cet effet, un premier électrolyte est appliqué sur l'anode (1) ex situ, en d'autres termes, avant assemblage de la pile au lithium à produire. A l'étape suivante dudit procédé, une seconde couche de protection (39 peut être appliquée pour stabiliser la première couche de protection (2).
