Abstract: The present application relates to a gluing nozzle and a gluing device. The gluing nozzle comprises an inner lined glue nozzle and an outer glue nozzle, wherein the inner lined glue nozzle comprises at least two sub-linings, and the at least two sub-linings are detachably connected and enclosed to form a glue cavity with a glue outlet; and the outer glue nozzle is detachably arranged on an outer side of the inner lined glue nozzle, such that the at least two sub-linings are relatively fixed. The gluing nozzle can solve the current problem that the production cost is increased since frequent replacement of a new glue discharging nozzle is required to ensure the uniformity of glue discharging.

Abstract: This application provides a battery and an electric device. The battery provided in this application is provided with a blocking member between two adjacent rows of battery cells along the length direction of the battery cell. In the process of assembling the battery cells in the box, the adhesive at the bottom of the battery cell, when spreading under compressing from the gap created by the housing chamfers to the end cover, will be blocked by the blocking member, thus preventing the adhesive from overflowing to the end cover, improving the safety performance of the battery.
