Abstract

The invention relates to the production of composite cathodes and anodes for lithium batteries, and the cathodes and anodes thereby produced. The active mass in the form of a thin film is incorporated into a material, or the active mass together with a matrix metal or a matrix alloy is deposited on a substrate. The invention also relates to a metallized, textile material made of insulating fibres which have been made conductive and which have been completely galvanically or electrolessly plated. The fibres lying on crossovers are not baked with other fibres, but can move freely. The surface of the material is thereby optimally used. Said material is preferably used as an anode or a cathode for batteries, especially a lithium battery, and fuel cells. During the galvanizing or electroless application stage in the production of the material, the fibres in the material move relatively to each other in order to avoid baking. A device for said production process comprises first rollers (13) with an elliptical cross-section and second rollers (14) with a diagonal circumferential profile (15), which extend or move the material (10) passing thereover, and conveyed thereby, in the longitudinal and lateral direction.
