Abstract
The present invention relates to a kind of preparation methods of precious metal simple substance adulterated vanadate nano-electrode material, belong to nanometer material and electrochemical technology field.Metal salt, ammonium metavanadate, two oxalic acid hydrates, six four ammoniums of methylene are dissolved in deionized water by a certain percentage, ultrasonic dissolution obtains presoma, presoma is moved into the autoclave containing substrate and carries out hydro-thermal reaction, there is the substrate of vanadate nano wire to clean load after reaction, it is dry, there is the substrate of vanadate nano wire to be immersed in soluble precious-metal salting liquid at 10 100 DEG C load later, takes out, cleans, is dry, finally using H again2High temperature reduction method under atmosphere, the precious metal ion being inserted into vanadic acid salt deposit by ion exchange is reduced to precious metal simple substance, obtain a kind of precious metal simple substance adulterated vanadate nano-electrode material, preparation process of the present invention is simple, reaction condition is mild and the reaction time is short, overall process non-secondary pollution object generates, and the electrode material of preparation has excellent chemical property.
Description
Technical field
The present invention relates to a kind of preparation methods of precious metal simple substance adulterated vanadate nano-electrode material, belong to nano material
With electrochemical technology field
Technical background
In recent years, due to economic sustained and rapid development, market is greatly have stimulated to changes such as coal, oil, natural gases
The demand of the stone energy.Up to now, more and more big environmental pollution and the energy weary pressure of hideing are increasingly prominent, find new replace
It is increasingly urgent for the energy, development energy conservation and environmental protection tool.Therefore, development new energy is to realize sustainable economic development, is solved increasingly
The effective way of serious environmental pollution.Wherein, lithium ion battery is especially noticeable due to unique superiority, such as ring
The advantages that border close friend, high-energy density, operating temperature range be wide, memory-less effect, has gradually attracted the sight of world community.With
Application the widening to the extensive energy storage field such as electric vehicle, intelligent grid of lithium ion battery, industry is to its cost and electricity
Chemical property has higher requirement, wherein the exploitation of high performance electrode material of new generation is the key that break through to apply bottleneck.And
Positive electrode is the key that lithium ion battery development, it is not only the restraining factors and lithium-ion electric of lithium ion battery price
The important determinant of pond power density and energy density.Therefore, low cost, high power capacity, high-power lithium ion battery anode material
The exploitation of material becomes the research hotspot of recent domestic academia.Vanadate intercalation materials of li ions is due to of low cost, synthetic method
