Abstract: A pressure relief apparatus includes a pressure relief body and a plurality of score grooves. The pressure relief body includes a pressure relief portion, and the pressure relief portion has a first surface and a second surface opposite to each other in a thickness direction of the pressure relief portion. A plurality of score grooves are sequentially arranged at the pressure relief portion in a direction from the first surface to the second surface. In two adjacent score grooves in the thickness direction, a maximum width of a score groove farther away from the first surface is less than a minimum width of a score groove closer to the first surface.

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.

Abstract: Provided are a method for preparing an organic light-emitting display panel, an organic light-emitting display panel, and a display device.

Abstract: This application discloses a content recommendation method performed at a computer device and belongs to the field of artificial intelligence. The method includes: acquiring a target user vector of a target user; determining n groups of seed user vectors according to the target user vector, each group of seed user vectors corresponding to a respective piece of candidate recommendation content; invoking a look-alike model to calculate a similarity between the target user vector and each group of seed user vectors, the look-alike model being used for calculating a similarity between user vectors based on an attention mechanism; and determining, among the n pieces of candidate recommendation content, target content to be recommended to the target user according to the respective similarities of the corresponding n groups of seed user vectors. This application can resolve a problem of relatively low accuracy of a recommendation method in the related art.
