The utility model relates to an ion exchange membrane used for a zinc-bromine flow battery, which is characterized by comprising a base membrane with a plurality of pores, and the pores are filled with high polymers with high conductive rate. In the utility model, the composite ion exchange membrane based on polytetrafluoroethylene and sulfonated high polymers is adopted, therefore, the ion exchange membrane not only has high mechanical strength, but also has very high ion conductivity, and high performance of a zinc-bromine battery is ensured; and simultaneously as the cost is low, possibility is provided for industrialization of the zinc-bromine battery.
Description
Technical field
The utility model relates to a kind of amberplex, particularly relates to a kind of amberplex that is used for zinc bromine flow battery.
Background technology
Zinc bromine electrokinetic cell is to be main with zinc bromine compounds and material with carbon element, is characterized in quickly-chargeable, but deep discharge; Need not under-voltage protection, the anti-antipole of battery, safe and reliable; Use has extended cycle life, and does not need battery management system, and is pollution-free; Cheap, be applicable to big bus, mini-bus Sightseeing Bus, the ferry-boat battery pack of waiting for bus.
The molecular bromine of zinc-bromine bettery is in the battery storing process; Can be diffused into negative electrode, generate zinc bromide with the metallic zinc reaction, this process is exactly a discharge process; That is to say the problem that in depositing process, has self-discharge of battery, thus cause need with the time battery do not have.Therefore, exploitation low-cost, high performance amberplex is the industrialized prerequisite of zinc-bromine bettery, and is visible, and in zinc-bromine bettery, amberplex is a key component wherein, and the performance of battery is had decisive influence.
Being applied to the zinc Australia topmost barrier film of flow battery at present is the Nafion film, and it allows cation to pass through, but stops the migration of bromine.In general, amberplex is bigger to the resistance of bromine, thereby can reduce self-discharge of battery, but this film is relatively more expensive.
The utility model content
The purpose of the utility model provides that a kind of cost is low, mechanical strength is high, have very high ionic conductivity, thereby can guarantee the high performance amberplex that is used for zinc bromine flow battery of zinc-bromine bettery.
For solving the problems of the technologies described above; The utility model is taked following technical scheme: a kind of amberplex that is used for zinc bromine flow battery; It is characterized in that: comprise basement membrane, in said hole, be filled with high molecular polymer with high conductivity with a plurality of holes.
Further, the porosity of said basement membrane is greater than 70%.
Further, said basement membrane is a poly tetrafluoroethylene.
Further, said high molecular polymer is a sulfonated polymer.
Further, said sulfonated polymer is any one or more in SPSF, sulfonated polyether sulfone, sulfonated polyether ketone, sulfonated polyimide, the perfluorinated sulfonic acid.
The utility model adopts the combined type amberplex based on polytetrafluoroethylene and sulfonated polymer polymer, therefore not only has high mechanical strength, and has very high ionic conductivity, thereby guaranteed the high-performance of zinc-bromine bettery; Simultaneously, because it is with low cost, therefore possibility is provided for the zinc-bromine bettery industrialization.
