提供离子导电复合电解质，其包括路径工程化的离子导电陶瓷电解质颗粒和固体聚合物基质。该路径工程化的颗粒特征在于具有各向异性晶体结构，以及晶体结构在与路径工程化的颗粒的个晶面相关的较佳的电导率方向H上的离子电导率大于晶体结构在与路径工程化的颗粒的另个晶面相关的降低的电导率方向L上的离子电导率。把该路径工程化的颗粒形成到所需尺寸并设置在聚合物基质中，从而大多数路径工程化的颗粒冲破基质主体的两个相对的主表面并在聚合物基质中取向，从而与降低的电导率方向L相比，较佳的电导率方向H更接近地对齐横跨基质主体厚度的最小路径长度。 An ion-conducting composite electrolyte (10) is provided comprising path-engineered ion-conducting ceramic electrolyte particles (20) and a solid polymeric matrix (30). The path-engineered particles (20) are characterized by an anisotropic crystalline structure and the ionic conductivity of the crystalline structure in a preferred conductivity direction H associated with one of the crystal planes of the path-engineered particle is larger than the ionic conductivity of the crystalline structure in a reduced conductivity direction L associated with another of the crystal planes of the path-engineered particle. The path-engineered particles are sized and positioned in the polymeric matrix (30) such that a majority of the path-engineered particles breach both
