To enable complete electrolyte impregnation of the electrode pores, the pouch cell must be exposed to a vacuum environment and then sealed. The process parameters must be controlled accurately throughout the entire process cycle; if the vacuum vent rate is too drastic, rapid gas evolution will cause electrolyte spillage and mass loss. If the final vacuum level is too low, the volatile electrolyte additives will evaporate. The heat sealing jaws must be hot enough to create a long-lasting seal but not so hot as to boil the electrolyte inside the pouch.

The Variant Energy Vacuum Sealer controls all of these critical parameters, which are stored in recipes accessible via the 7" touch screen. The unit has been specially designed to be utilized in a standard-size Ar glovebox.
