Abstract
Electrodes suitable for electrochemical cells are produced by a) applying a mixture comprising .alpha.) a solid III which can reversibly take up or release lithium ions in an electrochemical reaction and .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 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.

A process for producing electrodes (I) suitable for electrochemical cells, which comprises
- a) applying, by means of a coating apparatus (II), a mixture comprising
- .alpha.) a compound (III) which can reversibly take up or release lithium ions in an electrochemical reaction and
- .beta.) a binder (IV), or a compound which can be converted into a binder (IV), to an electrically conductive support (V) 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
- b) dividing 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.
