Description
Technical field
The utility model relates to flow battery fields, and in particular to a kind of flow battery slurries electrode assembly and a kind of liquid stream
Battery system.
Background technique
Flow battery is a kind of electrochemical energy storage technology for being suitable for extensive energy storage, is generally utilized in charge and discharge process just
The storage and release of energy are realized in the variation of active material valence state in pole and cathode liquid phase.Develop more mature system packet at present
Include all-vanadium flow battery, siderochrome flow battery and zinc-bromine flow battery.Flow battery has independent energy unit and power list
Member, energy unit refer generally to the anode and electrolyte liquid of battery, and the concentration and volume of active material determine liquid in electrolyte
The upper energy limit of galvanic battery, power cell refer generally to monocell or battery pile, and electrolyte flows through the electrode in battery pile, activity
Substance reacts in electrode surface, to convert electric energy for chemical energy, or converts electrical energy into chemical energy.
Flow battery generally uses circulation type (flow-through) electrode, electrode material by porous carbon, graphite or
Metal material is constituted, and the electrolyte comprising active material enters electrode inner surface by Pipeline transport to electrode inlet,
Electrochemical reaction occurs for the interface of electrode inner surface and electrolyte contacts, along with the change of active material valence state and obtaining for electronics
It loses, to realize the storage and release of electric energy.The size of electrode surface area determines the size of battery current, while electrode surface
Pore structure influence active material transmitting.Increase electrode surface area to be conducive to improve the ability that battery generates more high current, but
It is the aperture that can reduce electrode, thus the transmitting of restricted activity substance, therefore battery can not work under the conditions of more high current,
Performance boost encounters bottleneck.
Meng-Chan Li et al. (Nature, 520 (2015) 325) reports a kind of chargeable aluminium ion battery, the electricity
Pond has high power characteristic.The negative reaction of battery is the deposition and dissolution reaction of aluminium, and anode reaction is aluminum tetrachloride anion
Insertion and deintercalation reaction, electrolyte use nonflammable ionic liquid.The discharge platform of battery is 2V, and capacity is
70mAh·g-1, current efficiency 98%.The battery has good stability.But regrettably, the battery capacity is relatively low, still
So as common non-flow battery, does not have the function of capacity and power decoupled, be difficult to carry out extensive energy storage use.
All-vanadium flow battery is that a kind of research is more early, more deep, and has the flow battery of preferable Commercial Prospect.
It realizes the storage and release of energy using the variation for the vanadium ion valence state being dissolved in aqueous solution.Earliest patent report can chase after
It traces back to United States Patent (USP) " All-vanadium redox battery " (US4786567) in 1988.The battery is due to using water
Solution, nonflammable, there are no explosion dangers on fire.Electrode reaction region and active matter storage region are independent simultaneously, to realize
The structure of power and capacity, can according to need, and individually carry out the design of output power and capacity.In addition it is long with the service life,
The advantages that material recoverable.But its open-circuit voltage is relatively low, output power is relatively low.Simultaneously as vanadium reserves
Relatively limited, cost of material is higher, and energy storage is expensive.Therefore, actual commercial applications are by great challenge.
A kind of flow model ion battery is disclosed in US20150125764A1.The purpose is to so that it is had both lithium ion battery
The characteristic of high voltage, high-power advantage and flow battery power and capacity decoupling, makes it be not only suitable for the fields such as electric vehicle, again
Suitable for the extensive energy storage field such as wind-electricity integration.But since it is derived from lithium ion battery, the shape in initial charge is needed
At SEI passivation layer, but under the flow conditions, which can not continue to be formed, to be difficult to carry out subsequent reactions.Therefore, related to be somebody's turn to do
The exploration in field is still centered around basic theory and breaks through aspect.
It can thus be seen that needing to develop a kind of flow battery low in cost, chemical property is good at present.
