Method of at least partially filling an electrochemichromic device.

摘要

A method of filling an electrochemichromic device comprises providing the device with a filling aperture and evacuating it, lowering the device into an electrochemichromic solution and exposing the electrochemichromic solution to an inert gas at a pressure above that of the inside of the evacuated device to cause the solution to enter the device. The aperture in the device is then sealed.
