Cell assembly

The second phase of cell production: building the electrode–separator stack by winding or stacking, welding the tabs, inserting it into the case and filling the electrolyte. Most of it happens in the dry room.

Cell finishing

The third phase of cell production: formation, degassing, aging and end-of-line testing. It is slow and ties up capital — cells sit for weeks — which is why shortening it is a major research goal.

Electrode manufacturing

The first phase of cell production: mixing a slurry, coating it on foil, drying it, calendering to density and slitting to width. It is run as a continuous roll-to-roll line, and its consistency decides most of the final cell’s quality.

Gigafactory

A cell plant with an annual output of at least a few gigawatt-hours, enough for tens of thousands of electric cars. The term began as one company’s name for its plant and is now used for any large battery factory.
