Description
Technical field
The present invention relates to a kind of corrosion resistant composite current collector and preparation method thereof, specifically coat the layer of conductive film material, and can belong to Chemical Engineering and field of new as the manufacture method of electrode current collecting body in the electrochemical appliance at metal material surface.Can be widely used in fields such as chemical power source, physical power source, electrolytic industry, static desalination and corrosion protection, have a good application prospect.
Background technology
The collector of electrode plays a supportive role and the CURRENT DISTRIBUTION effect to electrode, is the important component part of electrode.In the use of chemical power source, electrolyte is one of reason of power-fail for the corrosion of electrode current collecting body, and particularly chemical power source corrodes easier generation when overcharging and put excessively.General, the anticorrosion of metal can or be electroplated corrosion-resistant coating and achieve the goal by the surface applied barrier coating.But barrier coating generally has holiday, thereby still can cause corrosion, and barrier coating is difficult to take into account conductivity, thereby can not be used for the guard electrode collector.And it is very limited to electroplate the optional material of corrosion-resistant coating, can not reach the corrosion-resistant purpose in a lot of use occasions.Metal corrosion preventing method also has the resist technology of sacrificial anode, and as electrode current collecting body, obvious this way is disabled.
In alkaline aqueous solution chemical power source system, the material that is used as collector generally is steel band, steel mesh, for preventing corrosion, generally nickel plating on steel band.The method that prevents corrosion of metals in acidic aqueous solution chemical power source system generally is lead plating.In static desalination or seawater, saline solution system, metal material commonly used, not corrosion-resistant as materials such as stainless steel, metallic nickel, metallic copper, metallic aluminiums.At present, the electrode current collecting body that can be used in static demineralizer and the seawater corrosion prevention is mainly selected titanium and tantalum and carbon class electric conducting material etc. for use.The metal material that titanium and tantalum are sea water resistances, the bitter corrosive nature is good, but the two production and processing cost are all higher, are unfavorable for large-scale application.Though carbon-based material is cheap and easy to get, electric conductivity is good, easily crisp when using as collector, make in electrode and the assembling process and very easily damaged.
Chinese patent CN1398306A adopts the method protective money metal surface of polyethylene copolymer base pyrrolidones macromolecule conductive film; because surface and copolymerized reaction is relevant with the activity of metal surface; can not accomplish activity all for the moment when the metal surface, still may cause active relatively poor site not form conductive protecting layer.Chinese patent CN1054389C adopts the method protective money metal surface of surface applied conducting resinl and forms conductive layer, and coating generally has holiday, thereby still can cause corrosion.Chinese patent CN1202177C is added with the conductive coating of sacrificial anode material in metal surface coating, is inappropriate for the collector of guard electrode.
