Abstract

Electrodes suitable for electrochemical cells are produced by PA1 a) applying a mixture comprising PA2 .alpha.) a solid III which can reversibly take up or release lithium ions in an electrochemical reaction and PA2 .beta.) a binder IV, or a compound which can be converted into a binder IV, to an electrically conductive support V by means of a coating apparatus II with essentially linear relative motion (R) of the support V relative to the coating apparatus II in such a way that an uncoated zone remains on the support V at each of the two margins of the coating apparatus II running parallel to the relative motion (R) and PA1 b) cutting the support V at an angle of from 5 to 85 degrees to the normal to the direction of relative motion (R) to give essentially parrallel strips.
