Description
Technical field
The present invention's is related to flow battery technology field, more particularly to a kind of flow battery ion-conductive membranes and its preparation
Method.
Background technology
Flow cell pile includes the structures such as electrode frame, positive and negative electrode and ion-conductive membranes.Electrode frame is hollow structure,
Positive and negative electrode is located therein dummy section, and ion-conductive membranes are located between positive and negative electrode, the both side surface of ion-conductive membranes
Surrounding edge is in close contact with electrode frame.
In prior art, when flow battery is assembled, cannot often realize directly using the ionic conduction under drying regime
Film (dry film) assemble pile, this be as untreated ion-conductive membranes are assembled on pile after, ion-conductive membranes
Water absorption and swelling phenomenon can occur with electrolyte contacts so that the area and size of ion-conductive membranes changes, and ion
The surrounding edge of conductive membranes is in close contact with electrode frame and is compressed, cause the part membrane material cannot continue after swelling to
Extend outside pile, so as to pile up a number of fold in the region, the appearance of fold will substantially reduce ionic conduction
Film and the sealing of both sides electrode frame, so as to increase the risk of pile internal electrical losses and leakage, reduce pile stable
Property, shorten the pile life-span.Therefore, to avoid problem above, the mode that pile is assembled in prior art is using moistening
State ion-conductive membranes (wet film) assembling pile, will dry film be first placed in water, electrolyte after complete wetting formed
Wet film carries out the assembling of pile again.
But there is following technical problem and defect using wet film assembling pile：
1. dry film infiltration is for, after wet film, the tensile strength of membrane material at least declines 20%, causes the longevity of ion-conductive membranes
Life is reduced, and after battery experience longtime running, ion-conductive membranes occur that situations such as crackle is even broken occurs.
2., due to having infiltrated a certain amount of liquid, inevitably there is lower thickness, aperture and becomes big problem in wet film,
The ion in fluid cell electrolyte is caused to be accelerated by the speed that film both sides are permeated so that the coulombic efficiency of flow battery
2%-3% is reduced, energy efficiency is also decreased.
3. wet film has the electrolyte of corrosivity and electric conductivity due to the public runner through-hole wall directly contact of its electrolyte,
When flow battery runs, the electrolyte reality infiltrated in the electrolyte of the public runner through hole of electrolyte and membrane material inside
Now turn on, so as to produce by-pass current so that interior leaky occurs again and again, and the electric energy for producing that leaks electricity is often with warm
Amount mode is consumed, so as to cause the public runner through hole of wet film electrolyte overheated (local temperature can exceed that 50 DEG C),
So that electrolyte active substance separates out and is formed the crystalline material of strong oxidizing property at high operating temperatures, these solid matter heaps
Product on the public runner of electrolyte of ion-conductive membranes has further speeded up ion-conductive membranes and has been particularly the public stream of electrolyte
The corrosion rate of road inwall so that ion-conductive membranes start hole occur, split from the public runner through hole of electrolyte first
Stricture of vagina, causes ion-conductive membranes entirety crack damage, pile integrally to be scrapped, and battery system cannot be continued to run with.
