Abstract: A pressure relief apparatus, a battery cell, a battery, and an electrical device are provided in embodiments of the present application. The pressure relief apparatus includes a pressure relief body and a score groove. The pressure relief body includes a pressure relief portion configured to be opened to relieve a pressure inside the battery cell when an internal pressure or temperature of the battery cell reaches a threshold. The score groove is arranged on the pressure relief body and includes a first arc-shaped groove and a second arc-shaped groove. The arc-shaped design of the first arc-shaped groove and the second arc-shaped groove makes it less likely that the pressure relief portion cannot be opened in a large area, thereby improving the safety of the battery cell.
