Title:
【発明の名称】ナトリウム―硫黄電池に用いられる高抵抗層の形成方法
Document Type and Number:
Japanese Patent JP2667551
Kind Code:
B2
Abstract:
PURPOSE:To improve the recoverability of the electric charging of a positive pole active material and also arrange so as not to give distortion to a solid electrolyte tube, by providing a high resistance layer between the solid electrolyte tube and a multi-bore quality electron conduction material within a positive pole chamber. CONSTITUTION:A high resistance layer 6 is provided between a solid electrolyte tube 1 and a multi-bore quality electron conduction material 5 filled within a positive pole chamber 4. The layer 6 consists of short fibre of an insulation quality and is arranged in a tube 1 length direction. As a result, sulfur atoms exiting to the vicinity of the tube 1 at the time of charging is restrained, so the charging recovery power of a positive pole active material becomes strong. In addition, even if the volume of the positive pole active material is decreased due to electricity charging, spreading is made uniformly and smoothly to the upper part of the tube 1, so no distortion is applied on the tube 1.
