Description
Technical field
The present invention relates to electrode material technical field, more particularly to a kind of electrode material for electric capacity manufacture.
Background technology
For capacitor as a kind of energy storage device, how to improve its energy density turns into the core capabilities of capacitor development,
And core component of the electrode material as capacitor, the quality of its performance directly determine the quality of capacitor performance.
From early 1980s, Germany scientist Gleiter [2] proposes the concept of nano crystal material, then uses
Artificial prepare obtains nanocrystal first, and since carrying out systematic researches to its various physical property, nano material has caused the world
Scientific and technological circle of various countries and the extensive concern of industrial circle.Nano material refers to characteristic size nanometer scale (being often referred to 1~100nm)
Fines composition solid material.Nano material has good skin effect, that is, refer to nano-particle surface atom with
The ratio between total atom number, qualitative change is caused after increased dramatically with diminishing for particle diameter.The particle size of nano material is small, position
Volume fraction shared by atom in surface is very big, produces sizable surface energy.With the reduction of nano-particles size, compare table
Area drastically increases, and surface atom number and ratio increase rapidly.Because surface atom number increases, specific surface area is big so that surface
Atom is in naked state.Surrounding lacks adjacent atom, Atomic coordinate number deficiency, unsaturated linkage be present, result in nanometer
There are many defects in grain surface, these surfaces is had very high activity, be particularly easy to adsorb other atoms or with other atoms
Chemically react.The activity of this surface atom not only causes nanoparticle surface to transport the change with configuration, while also draws
Play surface electronic spin, the change of conformation, electron spectrum.It is nano-particle and its solid material most important effect it
One.Due to nano-particle Presence of an interface effect and skin effect, thus produce particle surface excess charges, the phase of electric charge carrier
The characteristic such as interaction, the poly- number of evil spirit and particle stability and Task-size Controlling causes it to be expected to be applied in electrode material.
The content of the invention
Therefore, the present invention provides a kind of new electrode materials and preparation method thereof
