Separator for battery and method for manufacturing the same

電池用セパレータ及びその製造方法

Abstract

<P>PROBLEM TO BE SOLVED: To provide a separator for a battery for being compatible with high current and to provide a method for manufacturing the same. <P>SOLUTION: A solid electrolyte battery 100 is composed of a negative electrode 20/a solid electrolyte 10/a positive electrode catalyst 50/and an aqueous electrolyte 40, and a recessed and projecting shape having a surface roughness Ra of 2-100 μm is formed on the surface on the positive electrode catalyst side of the solid electrolyte 10. Since particles of the positive electrode catalyst 50 are densely filled in a recessed part 12, the contact surface between the surface of the solid electrolyte and the positive electrode catalyst is increased and high current is made possible. <P>COPYRIGHT: (C)2010,JPO&INPIT
【課題】大電流化に対応可能な電池用セパレータ及びその製造方法を提供すること。 【解決手段】この固体電解質電池100は、負極20/固体電解質10/正極触媒50/水系電解質40で構成されており、固体電解質10の正極触媒側表面には表面粗さRaが2μm以上100μm以下の凹凸形状が形成されている。正極触媒50の粒子は凹部12内に密に充填されている状態であり、これによって固体電解質表面との接触面積を増加でき大電流化を可能とする。 【選択図】図2
