Description
Technical field
The present invention relates to aluminium electrolutic capacitor preparation technical fields, and in particular to a kind of comprehensive high molecular aluminium electrolytic capacitor
Device is with helping carbon agent and its application method.
Background technique
In the prior art, solid-state aluminum capacitor mostly uses conducting polymer as electrolyte, and takeup type solid-state aluminum capacitor
Structure structure identical with takeup type liquid aluminum capacitor.What it is different from liquid is that adhere on the electrolytic paper of solid capacitor is to lead
Electric macromolecule, and what is adsorbed on liquid capacitor electrolytic paper is electrolyte.For liquid capacitor, electrolytic paper is the load of electrolyte
Body, the ion after electrolyte is adsorbed on electrolytic paper in electrolyte can pass through electrolysis paper layer still with free shuttling, therefore will not shadow
Ring the work of liquid capacitor.Although and the also carrier as solid state electrolysis paper of the electrolytic paper in solid capacitor, due to traditional electrolyte
The two-layer composite design that paper is usually used, one layer is then liquid-adsorption layer, and another layer is then ion barrier, it is however generally that is inhaled
Liquid layer is loose porous layer, and ion barrier is then compacted zone；Why solid capacitor sub-prime will be carbonized, mainly for
Compacted zone in electrolytic paper is carbonized into loose porous layer.The compactness structure and nonconducting property of one side will lead to solid
While state electrolyte is difficult to enter in capacitor, also results in solid electrolyte electric conductivity and be greatly reduced, so that solid-state
Capacitor unit for electrical property parameters deteriorates.
In order to avoid a series of problems caused by electrolytic paper property, solved at present using sub-prime carbonization technique.Sub-prime warp
After crossing high temperature cabonization, electrolytic paper can be carbonized, and electrolytic paper is on the one hand made to become loose porous, on the other hand the electrolytic paper of carbonization
Itself has certain electric conductivity, thus can solve electrolytic paper and adversely affects to solid capacitor bring.But this carbonizer
Although skill can effectively solve electrolytic paper bring adverse effect, but also bring along a series of problem simultaneously, be cost first
Increasing, carbonization needs to carry out sub-prime the carbonization treatment of (20~120min) for a long time in 250 DEG C~270 DEG C or so of temperature,
This needs many-sided cost input such as personnel, equipment, electric power.In addition, carbonization can seriously destroy the structure of cathode and anode foil, especially
It is that the oxidation film in anode foils can be made to generate many defects, this results in the performance of product extremely unstable, especially anode foils
It is exceeded to be that leakage current is easy.In addition to this, it is severe to will lead to workshop condition for high-temperature operation environment, and operator operation intensity increases,
Personnel rate is high.
Summary of the invention
Technical problem solved by the invention be to provide a kind of comprehensive high molecular aluminium electrolytic capacitor with help carbon agent and
Its application method can be used to solve to need to continue guarantor in the high molecular aluminium electrolytic capacitor production technology carbonisation of the prior art
