Abstract:
PROBLEM TO BE SOLVED: To provide an electro chromic medium enabling selection and maintenance of colors. SOLUTION: The electro chromic medium contains at least three kinds of electroactive materials having absorption spectra to be added together so that pre-selected colors can be obtained by individually selecting concentrations of at least three kinds of electroactive materials. The electro chromic medium retains colors pre-selected and sensed in a whole normal voltage range. The three kinds of electroactive materials contain one kind of electrochemically reducible material (cathodic material), one kind of electrochemically oxidizable material (anodic material), and one additional electroactive material which may be either an anodic or cathodic material. Three kinds of electroactive materials are in the medium and at least two kinds of them are anodic or cathodic materials. The selectable colors are, for example, red, orange, yellow, green, blue, and violet. At present, the color of the electrochromic mirror for vehicles is gray. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a color-stabilized electrochromic device having an electrochromic medium comprising one or more kinds of additives which serve to substantially preclude the formation of undesirable residual color within the electrochromic medium while the device is in its high transmission state. SOLUTION: The electrochromic medium (124) for use in a normally operating electrochromic device (100) comprises: (a) an anodic material and a cathodic material, wherein both are electroactive and at least one of the anodic material and the cathodic material is an electrochromic material; (b) an additive; (c) and a means associated with the additive for maintaining a colorless or nearly colorless electrochromic medium (124) while the electrochromic medium is in a high transmission state relative to an electrochromic medium (124) without the additive.

Abstract:
PROBLEM TO BE SOLVED: To provide an electrochromic device having one or more slow diffusive electroactive materials and an electron shuttle which improves the loss and/or the complexity associated with incorporating one or more slow diffusive electroactive materials into a medium of the electrochromic device. SOLUTION: An anode material and a cathode material are both electroactive. At least either one of the anode material and the cathode material is electrochromic. At least either one of the anode material and the cathode material is slow diffusive. The electron shuttle works to reduce a switching time of the electrochromic device having electron shuttle compared to a device without electron shuttle. COPYRIGHT: (C)2010,JPO&INPIT
