A liquid injection assembly, a sealing assembly, a cover plate and a battery

Abstract

The utility model provides a kind of battery's liquid injection assembly, hole sealing assembly, cover and battery, for with the liquid injection hole of battery connection, to inject electrolyte, this liquid injection assembly includes liquid injection suction nozzle, the bottom outside of liquid injection suction nozzle is equipped with first slope, the first slope gradually contracts inward from top to bottom, the top inside of liquid injection hole is equipped with second slope, the second slope gradually expands outward from bottom to top, the first slope is used to with the second slope and is set to fit;The liquid injection hole of the application is provided with second slope in head, and the liquid injection suction nozzle corresponding to the first slope is set, the contact area of liquid injection suction nozzle and liquid injection hole can be reduced, and residual electrolyte can be drained into the inside of battery, improve the injection precision, while effectively prevent electrolyte from remaining on receiving concave.
