In the invention, ions capable of continuously diffusing are provided by a flowing electrolyte salt solution, and the continuous supply of the salt solution is the basis for keeping the generated current continuous and constant.
Description
Technical field
The invention belongs to the design and the preparation method of new salts difference battery, what be specifically related to is the fluid salt difference battery of the novel sustainable power supply of a kind of having of salt error and the electrolytical salting liquid gang that flows is efficient, cleaning, advantage such as sustainable.
Background technology
The energy plays a part to closing heavy for the survival and development of human society, yet the product after the limited and burning of traditional fossil energy receives much concern the exploitation of renewable new forms of energy to the pollution of environment.New forms of energy such as solar energy, tidal energy, wind energy, oceanic energy and biomass energy owing to have cleaning, renewable, distribute extensively and concern, exploitation and the utilization of many incomparable advantage enjoy energy circle such as reserves are huge.Though the ocean occupy land surface huge be subject to reasons such as position and technology at present also not well by exploitation, utilize.Can and continue the fluid salt difference battery that the supply salting liquid organically combines and prepares novel sustainable power supply with the seawater salt error if design a kind of battery; And it can be developed and use in scale, the fluid salt difference battery of this novel sustainable power supply becomes the renewable and clean energy resource of this century and even following scale development and use surely.
Based on above thinking; The present invention's design is with salting liquid and the electrochemical cell gang with the electrolytical salting liquid of lasting supply; A kind of fluid salt difference battery of novel sustainable power supply is also prepared in design, and this battery has cleaning, renewable, the strong new pattern environment protection battery that can be widely used that does not receive the locus restriction that reaches of economic serviceability.
Summary of the invention
An object of the present invention is provides a kind of and utilizes cheap salting liquid to utilize the dispersal direction of its effects of ion and the different methods that prepare renewable clean environment firendly battery of speed in order again environment to be caused secondary pollution problem after the shortage problem that solves non-renewable primary energy and the burning.
Another object of the present invention is to improve the not high and non-renewable problem of the generation energy of traditional primary energy efficient.
A kind of design and manufacturing approach of fluid salt difference battery of novel sustainable power supply, what relate to is a kind of electrolyte solution that will continue to supply and salt error gang and the new salts difference battery for preparing.The fluid salt difference battery of this novel sustainable power supply is made up of following four parts: the electrochemical cell, pellicle, electrolyte solution and the electrode that contain the outlet of electrolyte injection opening and electrolyte flow.With regard to the architectural feature of this electrochemical cell, it is made up of a container, is divided into the two part containers that volume equates with barrier film in the middle of this container; Be respectively container one and container two; Wherein, require the big solution of concentration to be contained in the container one, hold pure water solution in the container two.The used barrier film of this electrochemical cell is a pellicle, and its principle schematic is shown in Figure of description 1.Container one separates with pellicle " 4 " with container two I, and this pellicle only allows the solution metal cation permeation and anion can not see through, and the yin, yang ion after the diffusion forms potential difference in the both sides of pellicle, utilizes this potential difference to form battery.Because container one is in continuous flow regime with solution in the container two, so the film both sides remain higher concentration difference, and the lasting supply of this electrolyte solution is constant and lasting assurance of holding current and basis.Electrodes use be the high platinum electrode of chemical stability.Originally the fluid salt difference battery characteristics of novel sustainable power supply are, do not receive the constraint of the exterior power and the energy, only with relying on different electrolytical concentration gradients just can continue generating, do not receive spatial constraints, and its application prospect is boundless.
Used pellicle is like the PETG film of functionalization, polyimide film, polycarbonate membrane, polystyrene film, polyethylene film, polychloroethylene film, the pellicle that polypropylene screen etc. see through at all interior cation selectives.
Used electrolyte is: NaCl, CuSO
4, FeNO
3Etc. the nitrate solution of the sulfate liquor of the hydrochloride solution of solubility, solubility and solubility and require the radius of metal cation to be less than anionic radius.
The fluid salt difference battery of this novel sustainable power supply can solve a large amount of power tenses and the borderland of basic nothing electricity and the electrical problem in mountain area in the industrial and agricultural production effectively; As long as the salting liquid of solubility is arranged, cationic optionally seeing through just can be taken place when it flows through pellicle and generate electricity.We be sure of, can play a sound assurance effect surely in the solution of fluid salt difference battery relevant energy problem in the raising of industrial and agricultural production and people's living standard of this novel sustainable power supply.
Originally the characteristics of the fluid salt difference battery of novel sustainable power supply are, do not receive the constraint of the exterior power and the energy, only utilize the electrolyte solution of variable concentrations just can generate electricity.And do not receive spatial constraints, application prospect is boundless.
The fluid salt difference battery of the novel sustainable power supply that the application is related is to utilize the concentration gradient of the electrolyte molecule generation of the variable concentrations that flows to generate electricity, and compares with traditional salt difference battery, and power-on time has very big prolongation, and theory is the endless time.The fluid salt difference battery of this novel sustainable power supply has novelty and using value more aspect the exploitation of new forms of energy.
The invention effect
Utilize the concentration gradient of flowing electrolyte effects of ion and combine to utilize pellicle ions diffusion principle to form electrical potential difference, directly produce electric energy and process novel battery through external circuit, its economy, the feature of environmental protection, recyclability is effective.Because the concentration gradient that the electrolyte solution that flows is constantly supplied ion, institute is so that produce current constant and constantly outwards output.Can be applicable to industry, agricultural, national defence, traffic, scientific research and industry such as civilian.Use this battery that realistic meaning is more arranged for the not really complete area of remote electric power facility especially.
Can know through above analysis and feasibility study; The liquid salt difference battery that the electrolyte solution that the present invention imagination will continue to supply variable concentrations is used to prepare novel sustainable power supply has wide material sources, cleaning, characteristic such as renewable, so the present invention has the value on the industry really.
