Electrode arrangement for nickel-cadmium accumulators and process of manufacture

摘要

A nickel-cadmium battery electrode structure is produced by stacking fibrous electrodes with an interposed separator material which has a different gas permeability in different directions and has cavities for temporary gas storage. A nickel-cadmium battery electrode structure is produced by stacking fibrous positive and negative electrode plates with interposed separator material to form an electrode packet, connecting electrodes of the same type together by pole bridges and pressing the electrode packet to compress and fix the separator material in a shape stable state. The separator material has a different gas permeability in different directions at least in the pressed and fixed state, so that gas transfer is prevented in the direction parallel to the surface of the electrode plates but is possible in the transverse direction, and has cavities for temporary storage of gas. An Independent claim is also included for a nickel-cadmium battery electrode structure produced by the above stacking, electrode connection and compression operations, the electrode packet being positioned between mechanical clamping elements. Preferred Features: The separator material is a fiber fleece of permanently elastic material.
