Abstract

The embodiments of the present application relate to the technical field of battery production, and disclose a formation system, comprising a clamp, a suction nozzle, and a negative pressure source, the clamp being used to clamp a battery, the suction nozzle being disposed corresponding to a liquid injection hole of the battery to collect formation exhaust gas from the battery, and the negative pressure source being connected to the suction nozzle to provide negative pressure environment for the suction nozzle, wherein there is a preset distance between the suction nozzle and the liquid injection hole of the battery to prevent electrolyte in the battery from being drawn out. The formation system according to the embodiments of the present application can prevent the loss of electrolyte caused by the electrolyte inside the battery being drawn out of a housing.

Claims (45)

1 . A formation system for formation of a battery, wherein that the formation system comprises:

a clamp for clamping the battery;

a suction nozzle disposed corresponding to a liquid injection hole of the battery to collect a formation exhaust gas of the battery; and

a negative pressure source connected to the suction nozzle to provide negative pressure environment for the suction nozzle;

wherein there is preset distance between the suction nozzle and the liquid injection hole to prevent electrolyte in the battery from being drawn out.

2 . The formation system according to claim 1 , wherein

the clamp comprises at least two limiting members disposed opposite each other at an interval, the battery is held between the two adjacent limiting members, and the two adjacent limiting member are movable relatively to change a clamping force on the battery.

3 . The formation system according to claim 2 , wherein

the clamp further comprises a base, on which each of the limiting members is movably disposed.

4 . The formation system according to claim 2 , wherein

the clamp further comprises a buffer member that is disposed on the side of the limiting member close to the battery and that abuts against the battery.

5 . The formation system according to claim 4 , wherein

the buffer member has a first surface that abuts against a second surface of the battery, with the projection of the first surface on the battery being within the second surface.

6 . The formation system according to claim 4 , wherein

the first surface of the buffer member is of an arched structure with the middle protruding outwardly.

7 . The formation system according to claim 1 , wherein

the suction nozzle is internally provided with a funnel-shaped channel, with the end of the channel having a larger area being disposed facing the liquid injection hole of the battery, and the other end being connected to the negative pressure source.

8 . The formation system according to claim 1 , wherein

the formation system further comprises an enclosure, with one end of the enclosure being sleeved on the suction nozzle, and the other end of the enclosure being disposed facing and close to the liquid injection hole of the battery.

9 . The formation system according to claim 1 , wherein
