Abstract
An electrode comprising a metallic lithium strip (1) and on at least one of its surfaces, at least one open-worked current collector strip (2), the ratio of the widths of the current collector strip(s) to the width of the metallic lithium strip ranging from 0.3 to 0.8, the proportion of openwork of each current collector strip ranging from 30 to 95%, the metallic lithium strip and the at least one current collector strip(s) being of substantially identical lengths. This electrode is advantageously used as the anode of a primary lithium electrochemical generator for example of the liquid cathode type such as Li/SO.sub.2, of the Li/MnO.sub.2 type or of the Li/CF.sub.x type with x comprised between 0.5 and 1 in order to reduce the quantity of non-discharged residual lithium.
