Grüne Keramikplatte für eine poröse Schicht, elektrochemisches Element, bei dessen Herstellung die grüne Keramikplatte verwendet wird, und Verfahren zur Herstellung des Elements

摘要

A ceramic green sheet which is fired to give a porous ceramic structure, and which is formed of a composition which principally consists of a ceramic powder, a binder, and a multiplicity of planar or elongate flakes which disappear upon application of heat, and which are oriented in the ceramic green sheet in a direction substantially parallel to opposite major surfaces of the green sheet. Also disclosed is an electrochemical element having a protective layer covering at least one electrode, which layer is prepared from the ceramic green sheet indicated above, and has a multiplicity of planar or elongate pores corresponding to the planar or elongate flakes included in the green sheet. A method of producing the electrochemical element is also disclosed.
