Zusammenfassung:A positive electrode including a positive electrode active material layer disposed on at least one surface of a positive electrode current collector, the positive electrode active material layer including a lithium transition metal phosphate, a fluorine-based binder, and a conductive material. The lithium transition metal phosphate includes a carbon coating layer formed on a surface thereof, and a ratio (B/A) of a total weight (B) of the fluorine-based binder to a total weight (A) of carbon of the conductive material and the lithium transition metal phosphate in the positive electrode active material layer is 0.7 to 1.7.
