Description
Technical field
The present invention relates to a kind of metal fuel battery, especially relate to a kind of novel metal fuel cell that can solve battery oneself corrosion under open-circuit condition.
Background technology
Along with science and technology develops rapidly, the people's living standard improves day by day, and people are constantly expanded the purposes of battery product, the consumption rapid growth of battery.Simultaneously various novel electron product functions are more and more complete, and power is increasing, and the energy of consumption is more and more higher, and the kind and the performance requirement of battery also improved constantly.And a large amount of in the market popular lead-acid batteries, lithium ion battery and Ni-MH battery, they or specific energy are on the low side, on the high side, if and when not using, do not recycle, be easy to contaminated environment, especially lead contamination, such development trend are to be difficult to satisfy the sustainable development of existing market and client's demand.
A kind of metal fuel battery has appearred on the market for this reason, it has that capacity is big, specific energy is high, stable operating voltage, abundant raw materials, cheap, pollute less even advantage such as pollution-free, be subjected to liking of client deeply, can adapt to simultaneously the economic development of social low-carbon environment-friendly, will be widely used in electric automobile or other the electronic products.
But the etching problem of metal fuel battery is perplexing academia always, be exactly all there is corrosion in metal anode no matter be in use or when not using.The focus that a lot of for this reason scientific and technical personnel set about at present delays corrosion in the Alloying Treatment of metal anode with this, but effect and not obvious, and also price is also expensive, can improve production cost undoubtedly, is unfavorable for development.For this reason, the scientific research personnel considers again to add sodium stannate or other materials in electrolyte, suppresses the oxidation of metal anode, extends the life of a cell, and corrosion still exists.
As from the foregoing, the corrosion phenomenon of metal fuel battery is inevitable, even still have the etching extent of every square centimeter of 30 days 1 gram under open-circuit condition, this has just influenced the effective utilization and the energy storage time of this high-specific energy battery greatly, and especially practicality is had a strong impact on.After the metal anode corrosion, also can be accompanied by the oxide that corrosion produces, influence the use of metal anode and battery.If this metal fuel battery is used on family's electric automobile, generally speaking, for the user of family, will be far smaller than unused time the service time of electric automobile, that is to say that the etching extent that metal fuel battery is in use produced is less than the etching extent that produces under the battery open-circuit condition, even car does not use the effective utilization and the energy storage time that can cause battery equally to reduce, produce the maintenance cost and the renewal cost of a metal fuel battery simultaneously, the consumer spending that this can increase the user is unfavorable for long-run development.This shows that solving these a series of problems has been extremely urgent.
In view of this; the inventor has done deep research to metal fuel battery; by feat of the experience of being engaged in relevant industries for many years and practice; design a kind of novel metal fuel cell; it is simple in structure, can solve the problem of corroding certainly under the metal fuel battery open-circuit condition, the protection metal anode; prolong the useful life of battery, this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of novel metal fuel cell, it is simple in structure, can solve the problem of corroding certainly under the metal fuel battery open-circuit condition, protection metal anode, the useful life of prolongation battery.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of novel metal fuel cell comprises electrolysis tank and is arranged on metal anode, air electrode and electrolyte in the electrolysis tank, it is characterized in that also comprising being arranged on the separator that metal anode, air electrode and electrolyte are separated.
Further, described separator comprises electrolyte container, pipeline and is arranged on and contains the control structure that electrolyte realize to be flowed on the pipeline;
Further, described control structure is a two-way pump valve;
Further, described separator is a travel mechanism that metal anode is moved up and down, and described travel mechanism is connected setting with metal anode;
Further, described separator comprises dividing plate and airbag structure, and described dividing plate is provided with through hole;
Further, described airbag structure comprises air bag, siphunculus and air pump, and described siphunculus connects air bag and air pump.
As everyone knows, battery has no idea to avoid corrosion in use, can only delay corrosion, but when not using, also there is etching problem in battery.Generally speaking, battery service time than the time of battery when not using long, come for a long time, that is to say that the corrosion major part of battery produces when battery does not use, be not subjected to absolute influence so battery and metal anode also can or not use because of the use of battery useful life.
Beneficial effect of the present invention: adopted separator among the present invention, this separator can make metal anode separate with electrolyte, especially under the battery open-circuit condition, more need separately, be that electrolyte does not contact with metal anode, stop chemical reaction between the two, this greatly reduces corrosion with regard to having solved the metal fuel battery open-circuit condition down from the problem of corrosion, improve the useful life and the effective utilization of battery and electrode, reduce the maintenance and the renewal cost of battery.
As from the foregoing, the present invention is simple in structure, can solve the problem of corroding certainly under the metal fuel battery open-circuit condition, protection metal anode, the useful life of prolongation battery.
In order further to explain technical scheme of the present invention, the present invention will be described in detail below by specific embodiment.
