摘要： A positive electrode plate includes a positive electrode current collector and a positive electrode material layer provided on at least one surface of the positive electrode current collector. The positive electrode material layer includes one-dimensional ion-conducting fiber and a positive electrode active material. The one-dimensional ion-conducting fiber has a diameter of 0.1 µm to 10 µm and a length-diameter ratio of greater than or equal to 1.5. A mass ratio of the one-dimensional ion-conducting fiber to the positive electrode active material is 0.01:1 to 0.2:1. The diameter and length-diameter ratio of the one-dimensional ion-conducting fiber as well as the mass ratio of the one-dimensional ion-conducting fiber to the positive electrode active material being controlled within the above ranges can reduce interfacial impedance between the positive electrode plate and a solid electrolyte and internal impedance of the positive electrode plate, thereby improving electrochemical performance of the electrochemical apparatus, for example, improving cycling performance and reducing impedance.

摘要： A battery system includes: a battery case (90); a battery (10) housed in the battery case (90), the battery (10) being composed of a sulfide-based all-solid-state battery; a first detection unit (71) located on a bottom surface (91a) of the battery case (90) inside the battery case (90) and configured to detect hydrogen sulfide; a second detection unit (72, 73) located vertically above the bottom surface (91a) inside the battery case (90) and configured to detect hydrogen sulfide; and a control device (150). The control device (150) includes an abnormality processing unit configured to perform an abnormality process based on detection results from the first detection unit (71) and the second detection unit (72, 73). The abnormality processing unit is configured to perform a first abnormality process when hydrogen sulfide is detected only by the first detection unit (71), and to perform a second abnormality process when hydrogen sulfide is detected by the second detection unit (72, 73).
