Problems solved by technology

[0007] The purpose of the present invention is to provide an asymmetric concentration difference battery for the technical problems existing in the existing concentration difference battery. The concentration difference battery of the present invention provides energy for the battery through the evaporation of water, and the concentration difference battery of the present invention has a stable voltage. , The current is continuous, only need to add water to maintain the concentration difference of the electrolyte solution at both ends of the battery, no additional electrolyte is required, under any environmental conditions, the pressure difference between the water vapor in the air and the saturated vapor pressure of the solution can be used Collect energy to continuously provide current to the outside world. The concentration battery prepared by the invention is an important supplement to traditional energy sources

Embodiment 1

[0069] Such as figure 1 , 2 As shown, the concentration difference battery of the present invention includes a container 1 for containing an electrolyte solution, a semipermeable membrane 2 that allows water molecules to pass through, two inert electrodes 3, a first electrolyte solution 4, a second electrolyte solution 5, a wire 6 and a separator plate 7.

[0070] The container 1 is divided into a first compartment 11 for containing the first electrolytic solution 4 and a second compartment 12 for containing the second electrolytic solution 5 by the partition 7 containing the semipermeable membrane 2, wherein the semipermeable The permeable membrane 2 is arranged on the partition 7, and is used for allowing the water molecules in the container to freely permeate through the partition and freely permeate between the first compartment and the second compartment.

[0071] The semi-permeable membrane 2 can be installed on any position of the partition 7, for example installed on...

Embodiment 2

[0094] Such as image 3 , 4 As shown, the concentration difference battery of the present invention includes a container 1 for containing an electrolyte solution, a semipermeable membrane 2 that allows water molecules to pass through, two inert electrodes 3 , a first electrolyte solution 4 , a second electrolyte solution 5 , and a wire 6 .

[0095] The container 1 is separated by the semipermeable membrane 2 into a first compartment 11 for holding the first electrolyte solution 4 and a second compartment 12 for holding the second electrolyte solution 5, the water molecules in the container, other than water Ions and molecules with small molecular diameters can freely pass through the semipermeable membrane 2 and freely permeate between the first compartment and the second compartment.

[0096] The top of the first sub-chamber 11 is open, which is beneficial to the volatilization of moisture in the first electrolyte solution; the top of the second sub-chamber 12 is provided wi...

Embodiment 3

[0112] Such as Figure 5 , 6 As shown, the concentration difference battery of the present invention includes two storage media 8 for absorbing and containing the electrolyte solution, a container 1 for placing the storage media 8, a semipermeable membrane 2 that allows water molecules to pass through, two inert electrodes 3, and a first electrolyte Solution 4 , second electrolytic solution 5 , wire 6 and separator 7 .

[0113] The storage medium 8 is composed of a hydrophilic polymer solid, such as polyvinyl alcohol (PVA), hydroxyethyl cellulose (HEC), starch grafted resin or cellulose ether, etc., and forms a gel state after absorbing water , to absorb or hold the electrolyte solution.

[0114] The container 1 is divided by the partition 7 containing the semipermeable membrane 2 into a first compartment 11 for holding the first electrolyte solution 4, a storage medium 8 for absorbing and containing the first electrolyte solution, and a second chamber for holding the second...

Abstract

The invention discloses a concentration cell comprising electrolyte solutions, a container used for containing the electrolyte solutions, a semipermeable membrane and noble electrodes. The container is partitioned into a first chamber and a second chamber, which are equivoluminal, through the semipermeable membrane; the noble electrodes are inserted into the electrolyte solutions in the first chamber and the second chamber respectively. The concentration cell is simple in structure, a stable, continuous and low-voltage low current can be obtained only by supplementing water periodically, and electrical energy which can be utilized directly can be generated by means of parallel connection of multiple concentration cells.

Description

technical field [0001] The invention relates to a device for collecting electrochemical energy, in particular to a concentration difference battery. Background technique [0002] Traditional energy is obtained from natural minerals such as coal, oil, etc. Due to the limited reserves and the pollution to the environment after burning, new energy has been valued and utilized by countries all over the world, such as solar energy, wind energy, geothermal, hydraulic power and tidal energy and so on. The use of these energies depends on an important condition - regionality. For example, the use of solar energy needs to be in a sunny area all year round, the use of wind energy needs to be in an area that is always windy, and geothermal and hydraulic power need special facilities. geographical environment. [0003] Concentration battery refers to a type of battery in which the change of substances in the battery is only from a high concentration to a low concentration of a substan...
