3.4 Some Alternative Approaches to Electrochromism:
A Brief Sketch
There is a multitude of alternatives to the oxide-based ''battery-type'' electro-
chromic device (Mortimer
2013
). One well-published option is to use a metal
hydride either on its own or in conjunction with an electrochromic film. The
hydride can attain a reflecting state under ion insertion, which offers principle
