Abstract
The present invention relates to a kind of preparation methods of high pressure resistant intensity capacitor material, belong to electronic material preparation technical field.The present invention is with bamboo chip, sawdust, iron powder etc. is that reaction solid is made in raw material, again will reaction solid high-temperature heat treatment and and silicon nitride, the materials such as zinc nitrate are mixed to prepare pre product, finally by pre product and triacetin, the material mixings such as neopelex, hot pressing, it calcines up to high pressure resistant intensity capacitor material, the present invention is from bamboo chip, bamboo fibre is extracted in sawdust, the organic principles such as lignin, bamboo fibre Surface Creation hydroxyl, the functional groups such as carboxyl, improve the mechanical strength of capacitor material microstructure, aluminium simple substance particulate component generates aluminium oxide in the present invention, absorption forms aluminum oxide film layer cladding carbon fiber between each aluminium oxide, it is improved the chemical stability of capacitor material, the electric conductivity of simultaneous oxidation aluminium is poor, the dielectric constant of capacitor material can also be improved, it has broad application prospects.
Description
Technical field
The present invention relates to a kind of preparation methods of high pressure resistant intensity capacitor material, belong to electronic material technology of preparing neck
Domain.
Background technique
Now with the sustainable growth of the rapid development of human society and energy demand, traditional fossil energy is caused sharply to subtract
Less, global ecological environment is worsening.It has been extremely urgent for greatly developing clean, the reproducible energy.Supercapacitor
As a kind of clean energy resource, the advantages that due to its high power density, fast charging and discharging and long circulation life, by scientific research circle and production
The close attention of industry.
Supercapacitor is a kind of new type of energy storage device of performance between physical capacitor and secondary cell, have than
The higher specific capacitance of ordinary capacitor and energy density, and there is power density more higher than battery simultaneously.Rely primarily on electricity
The electrochemical reaction or electric double layer of pole surface store charge, with charge and discharge are rapid, long service life, stability are good, work temperature
The advantages that degree is wide, circuit is simple, safe and reliable, environmentally protective, can be widely applied to auto industry, aerospace, science and techniques of defence,
The multiple fields such as information technology, electronics industry, have broad application prospects.
For electrode material as the deciding factor for determining performance of the supercapacitor, it decides the main property of supercapacitor
It can index.Ideal electrode material should specific capacitance, high rate capability and cyclical stability with higher.Supercapacitor root
Carbon electrode capacitor, metal oxide based capacitor and conducting polymer based capacitor can be divided into according to the difference of electrode material；Root
Double layer capacitor and faraday (counterfeit) capacity capacitor can be divided into according to the difference of energy storage mechnism.Faraday's capacitor is based on electricity
