Method for improved preloading of battery electrodes with metal ions, and preloaded battery electrodes with improved electrical properties

Abstract

The present invention relates to a process for producing an electrode for an alkaline ion ac-cumulator, wherein the process comprises at least the process steps: a) Providing an electrode layer pre-loaded with alkali ions and b) currentless contacting of the pre-loaded electrode layer provided in process step a) with a solution comprising an organic solvent and at least one additive dissolved therein, the addi-tive being selected from the group consisting of carbon dioxide, organic carbonates, organic silanes, derivatives thereof or mixtures of at least two additives from this group, and cur-rentless deposition of at least part of the additive onto the pre-loaded electrode layer in the absence of an electrolyte salt. Furthermore, the present invention relates to pre-loaded elec-trodes produced by the process according to the invention and to the use of the process for producing electrodes for alkaline ion accumulators.
