Battery Manufacturing EquipmentHangke vacuum electrolyte filling station
Hangke's vacuum electrolyte filling station injects electrolyte into cells under vacuum with automatic, intelligent control. Hangke gives an injection precision of ±1%. The station sits between cell assembly and formation, and the dose, vacuum sequence and electrolyte are set for each cell design with the supplier.
The ±1% precision figure and what to ask
Hangke lists precision, automation and intelligent control, with no model, dose range, dosing mechanism, nozzle count or vacuum level. It does not say whether ±1% is measured against target mass, delivered volume or a calibration condition. Ask Hangke for the reference, the dose it applies to and the repeatability figure.
Send the cell opening drawing, electrolyte formula, temperature and target dose. Ask for the configuration offered and confirm the wetted materials suit your electrolyte. The offer should name the wetted parts, pumping and metering method and seals. Ask which vacuum, hold and vent steps are included and which pressure reference is used.
| Parameter | Published value | Record status |
|---|---|---|
| Published injection precision | ±1 % | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Checking the dose that reaches the cell
Agree how the delivered dose is checked against traceable references, and how liquid held in the nozzle, drips and line residue are handled. The pump setting and the amount left in the cell can differ. If weighing is offered, specify the scale, tare sequence and the timing of the before-and-after weights used for comparison.
Run your target dose and electrolyte through the supplied sequence and keep the settings and each result. Include the planned start and restart and any dose change. Agree how an incomplete fill, a wrong cell ID and an out-of-limit reading are handled. Hangke gives no rate or wetting data, so measure fill rate and wetting time on your own cells.
Environment, services and the next step
With the supplier and your site team, specify the working environment and the containment and handling needed for your electrolyte. List drying and purging, exhaust, vacuum services, transfer vessels and maintenance access where needed. Ask whether a dry room, solvent treatment or a leak-tested link to the sealing station is part of the offer, or must be sourced separately.
Define how the filled cell is passed on, the longest allowed wait and the temporary or final closure that follows. Ask for cleaning, changeover, line-emptying and interrupted-cycle instructions. Base acceptance on the measured delivered dose and the agreed sequence on your own cells, and use it for any comparison with other filling machines.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| What does ±1% refer to? | The catalogue gives ±1% with no dose range, units or measuring conditions. | Fix the reference dose and a traceable method for checking delivered dose. |
| Does the vacuum sequence match the cell? | The catalogue names vacuum filling without a pressure-time recipe. | Approve the cell drawing and the fill, hold and vent sequence. |
| Where does the filled cell go next? | The catalogue does not describe transfer or closure after filling. | Define transfer state, maximum wait and closure interface. |
