The invention provides an electrochromic device. Prior electrochromic devices frequently suffer from poor reliability and poor performance. Some of the difficulties result from inappropriate design and construction of the devices. In order to improve device reliability two layers of an electrochromic device, the counter electrode layer and the electrochromic layer, can each be fabricated to include defined amounts of lithium. Further, the electrochromic device may be subjected to a multistep thermochemical conditioning operation to improve performance. Additionally, careful choice of the materials and morphology of some components of the electrochromic device provides improvements in performance and reliability. In some devices, all layers of the device are entirely solid and inorganic. 本发明提供了种电致变色装置。先前的电致变色装置常常存在可靠性差和性能差的问题。些问题是由装置不恰当的设计和构造引起。为改良装置的可靠性，电致变色装置的两层，即反电极层与电致变色层各自可经制造以包括规定量的锂。此外，电致变色装置可进行多步热化学调整操作以改良性能。另外，谨慎选择电致变色装置的些组件的材料和形态，以改良性能和可靠性。在些装置中，装置的所有层都是完全固体和无机的。
