| 1. An electrochromic device comprising:
a first electrode comprising one of an electrochromic electrode layer and a counter electrode layer,
a second electrode comprising the other of said electrochromic electrode layer and said counter electrode layer,
an ion-conductor layer for conducting ions between said first and second electrodes comprising at least two ion transport
layers and a buffer layer, said at least two ion transport layers and said buffer layer alternating within said ion conductor
layer such that said ion transport layers are in communication with said first and second electrodes,
a first conductive layer, and
a second conductive layer,
said first and second electrodes and said ion-conductor layer being sandwiched between said first and second conductive layers.
