Energy storage device and preparation method thereof.
Background technique
The consumption of the energy in modern architecture accounts for a big chunk of mankind's energy wastage in bulk or weight, is mainly derived from system
Heat, refrigeration, the demand of illumination aspect.The use of electrochromic intelligent window can effectively reduce the consumption of the modern architecture energy.It is electroluminescent
After application of a voltage, light transmission will change correspondingly off-color material, macroscopically show as electrochromic material color
Variation, and have stable, required voltage compared with small, light transmission adjustable range is big, can meet the excellent of a variety of demands of people simultaneously
Point.By the way that electrochromic material is fabricated to so-called " intelligent window ", user can adjust " smart window according to their own needs
The variation of the light transmission at family ", indoor shading value, temperature can be adjusted therewith.
Most of electrochromic device suffers from five-layer structure, is successively transparency conducting layer, electrochromic layer, ionic conduction
Layer, ion storage, transparency conducting layer.Transparency conducting layer is generally divided into tin-doped indium oxide glass (ITO) and fluorine-doped tin oxide glass
Glass (FTO)；Electrochromic layer is the core of entire electrochromic device, and generally electrochromic layer should have biggish
Spectrum adjustable range has higher electronics and ionic conductivity；Electrolyte layer can be liquid or solid, used at present exhausted
Major part is liquid electrolyte, but solid electrolyte is not due to having the problem of liquid electrolyte leakage gradually to be favored yet；
Ion storage primarily serves the effect of balancing charge.Electrochromic material is broadly divided into organic and inorganic two major classes, Organic Electricity
Cause off-color material for example: polyaniline, polypyrrole etc.；Inorganic electrochromic material is for example: Prussian blue, tungstic acid, titanium dioxide
Titanium etc..By taking tungstic acid as an example, it is blue in colored state, corresponding to W that tungstic acid, which is colorless and transparent in bleached state,6+
With W5+Transformation between ionic valence condition.
Although required voltage is smaller for electrochromic material, but still needs external power supply, this makes total more multiple
It is miscellaneous.Then people are sought for being not required to the method that external power supply can allow electrochromic material transmissivity to change, by solar-electricity
It is exactly an effective method that pond and electrochromic material, which are combined together to form a new photovoltaic electrochromic device,.
Wherein, dye-sensitized cell (DSSC) was particularly subject to due to the advantages that its is of simple structure and low cost, environmentally protective
The concern of people.The Chinese patent literature that patent publication No. is CN102183863A disclose a kind of Photoelectrochromic device and its
Preparation method, for light anode using the titanium dioxide for adsorbing dyestuff, electrochromic layer is that polythiofuran derivative class is electroluminescent
Optically variable films, electrolyte are the carbonic allyl ester solution of lithium iodide, and transparent conductive substrate is TCO glass, are had under light illumination
38% optics regulation rate and more excellent cycle performance, but the not function of energy stores.
For another example G.Leftheriotis et al. (Solar Energy Materials&Solar Cells, 2012,96,86-
92) a kind of part cover type photovoltaic electrochromic device is assembled, is that deposited by electron beam evaporation method makes three oxygen on ito glass
Change W film, layer of titanium dioxide film is then made on WO 3 film, dyestuff is anchored on titanium deoxid film, platinum
It being plated on another ito glass and makees to electrode, centre is the carbonic allyl ester solution of lithium iodide and iodine, under sunlight irradiation,
Become coloured state from transparent state；Under no illumination, tungstic acid becomes transparent state again.Though the photovoltaic electrochromic device has centainly
Optics degree of regulation and cycle performance, but the also not no function of energy stores.
