Description
Technical field
The present invention relates to a kind of preparation method of Optical devices, particularly relate to a kind of have that good lithium ion embeds and the electrochromism electrode of the nickel oxide layer of moving out with and preparation method thereof, wherein this electrode can be used for the heat-tinting electrode in a kind of electrochromism device.
Background technology
The characteristic of electrochromism membrane electrode generally is to change over colored state or be varied to vitreous state from colored state from vitreous state for changing its optical property when the embedding of positively charged ion and electronics or when moving out membrane structure, and its colour-change is a reversing process.This kind electrochromic material has many industrial application, for example: intelligent type energy saving window, sun roof, glareproof mirror, indicating meter and transmitter etc.
The coloring mode of electrochromic material can be divided into two kinds: first kind is called negative electrode painted (cathodiccoloration), painted when being positively charged ion and electronics embedding membrane electrode, and when positively charged ion and electronics are moved out membrane electrode, discolor, with this kind/thin-film material of the mode of discoloring has Tungsten oxide 99.999, molybdenum oxide, titanium oxide, Viology and PEDOT etc.; Second kind is called anode painted (anodic coloration), discolor when being positively charged ion and electronics embedding membrane electrode, and painted when positively charged ion and electronics are moved out membrane electrode, with this kind/thin-film material of the mode of discoloring has nickel oxide, iridium oxide and Prussian blue etc.
Nickel oxide film is the common painted electrochromic material of anode, presents vitreous state when positively charged ion and electronics embed film, and presents chocolate when positively charged ion and electronics are moved out film.The preparation method of nickel oxide film electrode has hot evaporation, sputter, sol-gel method and electrochemical deposition etc.In these preparation methods, electrochemical deposition method is a most convenient and cheap, and easily by adjusting size of current, solution composition and depositing temperature come the thickness of controlled oxidation nickel film.
During the electrochromism characteristic of most of research nickel oxide film electrode, all with the basic metal aqueous solution as ionogen, and the painted reaction of nickel oxide film can be expressed as follows:
Ni(OH)
2+OH
-→NiOOH+H
2O+e
-
Transparent (transparent) dark (darken)
The nickel oxide of divalence is oxidized to tervalent nickel oxide in the following formula, and film becomes chocolate by transparent transition.When above-mentioned reaction reversed, nickel oxide film was transformed into clear, colorless.Yet in complementary type electrochromism assembly (tungsten oxide film is that the working electrode nickel oxide film is a counter electrode), the basic metal aqueous solution is not suitable for as the ionogen in the assembly, because aqueous alkaline electrolyte can cause the dissolving of tungsten oxide film electrode.Therefore, based on the non-aqueous electrolyte of lithium ion, as lithium perchlorate (LiClO
4) be dissolved in the ionogen that propylene carbonate (propylene carbonate) forms and then select for the ionogen of complementary assembly the best, this kind ionogen can make assembly have secular operational stability.Therefore, the lithium ion character that embeds/move out nickel oxide film just seems suitable important.In order to make the process that lithium ion can carry out fast and reversible embeds and moves out in the nickel oxide film, traditional nickel oxide film need utilize electrochemical method to carry out the program of so-called initial activation.One of method of initial activation nickel oxide is exactly to apply repeatedly Eo+ to being immersed in the membrane electrode that contains in the lithium-ion electrolyte, makes lithium ion partly embed and form the lithium nickel oxide film in the nickel oxide film that its chemical equation is as follows:
NiO
x+yLi
++ye
-→Li
yNiO
x
Wherein, the initial lithium ion that embeds has activated the agent structure of nickel oxide film, makes this film can subsequently carry out the process that the reversible lithium ion embeds/moves out.Yet, the redox potential that applies how many cycle indexes just can make it to have the process that good lithium ion embeds/moves out in the nickel oxide membrane electrode, main according to script nickel oxide depositing of thin film condition, need to carry out tens of inferior film reactivation processs usually at least.But, if needing to carry out activation treatment earlier in electrolytic solution before use, could use membrane electrode, can increase the programstep of extra cleaning film electrode like this, and cause the complexity on the processing procedure, and increase manufacturing cost.
In view of this, people such as M.Rubin uses LiNiO
2As target, directly deposit the lithium nickel oxide membrane electrode in the mode of sputter, reduce the required activatory cycle index of film for once.But, use the sputtering method deposit film to need expensive vacuum apparatus, can't effectively reduce manufacturing cost.
