Problems solved by technology

[0002] The ion concentration battery uses high-concentration solution to diffuse to low-concentration solution, and forms a potential difference on the diffusion interface due to the different diffusion rates of ions. The prior art discloses a concentration battery for sustainable power generation. The application number is 201610316408.9. Poor battery includes positive electrode, negative electrode, electrode partition, high concentration solution inlet, low concentration solution inlet, high concentration solution container, low concentration solution container, solution outlet after power generation, high concentration solution supply system and low concentration solution supply system, The disadvantage is that there are continuously high-concentration solutions and low-concentration solutions on both sides of the electrode partition, and the high-concentration solutions and low-concentration solutions on both sides of the electrode partition are discharged before they are fully diffused, and the power generation efficiency is low. In addition, the pressure on both sides of the electrode partition It is difficult to achieve complete consistency, so it is difficult to form a stable solution interface where the high-concentration solution contacts the low-concentration solution
