Abstract
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.
