US Patent:
20130273422, Oct 17, 2013
Filed:
Sep 1, 2011
Appl. No.:
13/882224
Inventors:
Marcus Wegner - Leonberg, DE
Jens Grimminger - Leonberg, DE
Martin Tenzer - Unterensingen, DE
Timm Lohmann - Mountain View CA, US
International Classification:
H01M 4/1395
US Classification:
429212, 429209, 296235
Abstract:
In a method for producing an anode for a lithium cell, and/or a lithium cell as well as anodes and lithium cells of this type, to extend the service life of the lithium cell and to selectively form a first protective layer including electrolytic decomposition products, on an anode including metallic lithium, a first electrolyte is applied on the anode ex situ, i.e., prior to assembling the lithium cell to be produced. To stabilize the first protective layer, a second protective layer is applied in a subsequent method step.
