Cylindrical Cell Electrolyte Filling and Vacuum Degassing Machine for Laboratory Use
l The cylindrical cell electrolyte filling & vacuum degassing machine is equipment applied to electrolyte filling and vacuum degassing processes for cylindrical cells.
l This equipment adopts a desktop design. The operator places cells into the fixture, presses the start button, and the machine performs automatic filling. After filling is completed, it automatically performs vacuum degassing.
l The equipment can be used inside a dry room, and is an ideal choice for laboratories and research institutes for pouch cell sample production.
Operator places the cell into the fixture and presses the start button → Automatic electrolyte filling & vacuum degassing → Operator removes the cell

1 |
Fixture |
1 |
a) Place 18650 cells on the fixture in a 5 × 5 layout.
b) When changing models, only the fixture needs to be replaced.
c) The fixture is equipped with dowel pins for precise positioning. |
|

Filling mechanism |
1 |
a) Y-axis of filling adopts a module for position movement; spacing and number of fillings can be set.
b) Z-axis of filling adopts a cylinder.
c) Filling nozzle material: SUS316. |
|
3 |
Vacuum degassing |
1 |
a) Perform vacuum degassing on the cell after filling (time adjustable).
b) Vacuum can be controlled ≤ −90 kPa.
c) Pressure-holding time and cycles ≤ 6.
d) Equipped with analog vacuum gauge (vacuum set on touchscreen).
e) Vacuum leakage per minute ≤ −3 kPa.
f) With power-off / air-loss protection. |

Filling pump (metering pump) |
1 |
a) Filling amount adjusted by micrometer, simple and convenient.
b) Precision ceramic valve with reciprocating rotary motion.
c) Static seals: EPDM.
d) Ceramic pump core material: alumina, wear-resistant.
e) Filling accuracy: ≤ ±5‰ g.
f) Single maximum filling amount: 5 g, multiple fillings can be realized. |
|
5 |
Electrolyte tank system |
1 |
a) Equipped with two tanks: storage tank and filling tank.
b) Automatic liquid feeding.
c) Storage tank has degassing function—rotating while vacuuming; after bubble removal, flows into the filling tank.
d) Inlet equipped with filter screen.
e) Storage tank low-material alarm.
f) Filling tank low-material alarm causes machine stop.
g) Tank material: SUS316.
h) Seals: corrosion-resistant (EPDM).
Each storage tank capacity ≥ 2 L; each storage tank must be installed with 4 level sensors, to detect level status. During liquid feeding, if the level does not change, the equipment shall alarm. |
