    • Disclosed herein are inner electrodes of a multilayered ceramic capacitor including metal powders including graphene layers formed on a surface thereof and a multilayered ceramic capacitor including the inner electrodes. An exemplary embodiment of the present invention can include metal powders including graphene layers formed on a surface thereof as inner electrode materials of a multilayered ceramic capacitor to more effectively prevent necking of the metal powders than the related art including only dielectric ceramic powders, thereby increasing necking temperature and necking and control inner electrode shrinkage, thereby reducing a thickness of the inner electrode and defects such as short/cracks, and the like, of the inner electrode. Therefore, it is possible to provide the multilayered ceramic capacitor with excellent reliability by minimizing a difference in shrinkage between the dielectric layer and the inner electrodes.
    • 这里公开了包括形成在其表面上的石墨烯层的金属粉末和包括内部电极的多层陶瓷电容器的多层陶瓷电容器的内部电极。 本发明的一个示例性实施例可以包括金属粉末,其包括形成在其表面上的石墨烯层作为多层陶瓷电容器的内部电极材料,以比仅包括介电陶瓷粉末的现有技术更有效地防止金属粉末的颈缩,从而增加颈缩 温度和收缩和控制内部电极收缩,从而减小内部电极的厚度以及内部电极的短路/裂纹等的缺陷。 因此,通过最小化介电层和内部电极之间的收缩差异,可以提供具有优异的可靠性的多层陶瓷电容器。
