Technical Field

[0001] The utility model relates to the technical field of button battery production equipment, in particular to a novel liquid injection device for button battery production. Background Art

[0002] A button battery, also known as a button cell, is a battery that looks like a small button. The button battery is composed of a positive electrode cover, a rubber ring and a negative electrode cover that are pressed together.
