1. A method of in-line printing electrolyte patterns of electrochemical cells comprising the steps of:
- formulating an electrolyte composition having low adhesive properties;
printing the electrolyte composition having low adhesive properties in a repeating pattern along an advancing web; and
chemically transforming the electrolyte composition of the printed electrolyte patterns along the advancing web from an electrolyte composition having low adhesive properties to an electrolyte composition having high adhesive properties.

Abstract
An electrolyte is formulated as a printing ink and laid down by an in-line press for manufacturing printed electrochemical cells. A curing station transforms the electrolyte to perform additional functions such as separating electrodes, preventing leakage, bonding cell layers, and resisting evaporation.
