Active Lithium Reservoir For Lithium-Ion Batteries |
摘要 |
The present invention relates to methods for providing an active lithium reservoir to reduce the irreversible initial losses and as a general lithium source of or for electrode materials and lithium batteries, and a powdered lithium-donating material having an electrochemical potential of 0.5 and 2 V vs. Li/Li+, which has been selected from the group of lithium hydride, lithium amide, lithium imide and tetra-lithium ammonium hydride, is used as a general lithium source. |

1. A method for providing an active lithium reservoir for lithium batteries, characterized in that at least one hydrogen-containing lithium-donating additive selected from the group of lithium hydride, lithium amide, lithium imide and tetra-lithium ammonium hydride is used, which is electrically contacted by a potential which is at least equal to the standard oxidation potential in such a manner that it decomposes under release of lithium and formation of gaseous by-products. |
