Technical field
It uses liquid metal gallium for the aluminium ion battery of cathode the present invention relates to a kind of, belongs to field of electrochemical batteries, have
Body can get without dendrite, aluminium ion battery cathode anticorrosive, can be recycled, and finally obtain the long-life, high-energy density,
The extensive energy storage of safety and stability or automobile power aluminium ion battery.
Background technique
With the continuous reduction of the non-regeneration energies such as petroleum, coal, natural gas, and its caused by environmental problem highlight,
It develops and becomes current research hotspot using reproducible green novel energy source.Wherein, electric energy is undoubtedly a kind of clean, and
The important energy source of number of ways (such as waterpower, wind-force, solar energy) collection can be used.However, the collection process of electric energy often companion
With intermittent, noncontinuity process, it is therefore necessary to be stored in secondary cell, realize persistently answering for electric energy with this
With.
In the past few decades, lead-acid accumulator is because cheap, easily fabricated and be widely used, however its energy
Metric density is low, and pollution problem caused by old and useless battery is serious；Therefore, energy density height, the lesser lithium-ion electric of environmental pollution
Pond is developed rapidly.However, lithium content is less in the earth's crust, and lithium battery is easy to happen on fire, explosion during military service
Equal danger, therefore develop the research hotspot that novel secondary cell system is the current field.
In contrast, there are a large amount of aluminium elements in the earth's crust, and aluminium itself has excellent theoretical energy density
(2980mAh g-1, 8040mA h cm-3), while will not be occurred based on room temperature aluminium chloride-inorganic salt system aluminium ion battery
Burning and explosion.Therefore, aluminium ion battery be expected to become next-generation, low cost, can large-scale application secondary cell system.Thing
In reality, the research about aluminium ion battery has been achieved for tremendous development, and it is flat to have developed serial high capacity density, high work
The positive electrode (such as pyrolytic graphite, nickel sulfide, copper sulfide, tellurium, selenium) of platform.Meanwhile about novel flexible, wide temperature, wide electricity
The aluminium ion battery electrolytic solution of gesture window is also evolving.However, the negative electrode material of battery but there is no excessive concern,
Still using metallic aluminium as cathode.Although aluminum honeycomb is low in cost, theoretical duty density is high, however it is in cyclic process, because
Burn into dendrite problems caused by nonuniform deposition/dissolution of aluminium are serious, and eventually lead to cathode powdered, battery permanent failure.
In addition, the aluminum honeycomb of powdered can not utilize again, the waste of metallic aluminium is ultimately caused.
Summary of the invention
Based on the studies above background, the present invention proposes a kind of aluminium ion battery for using liquid metal gallium as cathode.Liquid

The selection of the diaphragm specifically: when interpolar is away from being greater than 5mm between positive and negative electrode, and battery is not need mobile storage
When energy battery, it may be unnecessary to diaphragm；When interpolar needs to add diaphragm away from being less than when 5mm or battery need mobile between positive and negative electrode,
Diaphragm material can be glass fibre, or polypropylene micropore diaphragm.
Aluminium ion battery relative to tradition using aluminum metal as cathode, the present invention using liquid gallium as cathode, gained aluminium from
Sub- battery has many advantages, such as to have extended cycle life, energy density is high, safety and stability.
Compared with the existing technology, beneficial effects of the present invention are as follows:
1) Al dendrite, will not be generated in cathode cyclic process, reduces the risk of internal short-circuit of battery；
2), etching problem is not present in cathode, its effective affecting acreage will not change in cyclic process, therefore can be effective
Improve the cyclical stability of battery；
3) the gallium cathode after, recycling can be recycled further, therefore can reduce the cost of battery, reduce metallic aluminium
Waste.
