Claim Text:
1. An ion-conducting composite electrolyte comprising ion-conducting ceramic electrolyte particles and a solid polymeric matrix, wherein: the solid polymeric matrix comprises a first major face, a second major face opposing the first major face, a matrix body defined between the first and second major face, and a minimum path length x spanning a thickness of the matrix body; the ion-conducting ceramic electrolyte particles are characterized by an anisotropic crystalline structure comprising a plurality of crystal planes; each ion-conducting ceramic electrolyte particle of a majority of the ion-conducting ceramic electrolyte particles comprises a first crystal plane and a second crystal plane; the first crystal plane extends in a direction H and comprises a first ionic conductivity in the direction H; the second crystal plane extends in a direction L different from the direction H and comprises a second ionic conductivity in the direction L; the first ionic conductivity in the direction H is larger than the second ionic conductivity in the direction L; each ion-conducting ceramic electrolyte particle of the majority of the ion-conducting ceramic electrolyte particles is oriented in the solid polymeric matrix such that the direction H is more closely aligned with the minimum path length x than is the direction L; and each ion-conducting ceramic electrolyte particle of the majority of the ion-conducting ceramic electrolyte particles is sized and positioned in the solid polymeric matrix to breach both the first and the second major faces of the solid polymeric matrix.
