NEGATIVE ELEKTRODEN ZUR VERWENDUNG IN AKKUS, DIE AUF DEM PRINZIP DER INSERTION UND EXKLUSION VON IONEN ODER DER LEGIERUNGSBILDUNG BERUHEN, UND AKKU, DER EINE SOLCHE ELEKTRODE UMFASST

摘要

The invention relates to a negative electrode for a battery operated according to the principles of ion insertion and decompression and / or alloy formation and detachment-The first surface of the collector contains a first layer of active substance deposited through the surface of the collector（-The second layer (7) contains an active material deposited on a second surface of the current collector (5) through one of its surfaces, and the first surface is opposite to the second surface;It is characterized in that the current collector (5) has a through hole ((6) for connecting the first layer to the second layer, and the first layer is coated with a layer composed of metal (1, 1, 1, 4). The corresponding cations are cations in the process of ion insertion or detoxification and / or in the formation and removal of alloys in the active materials of the first and second layers.
