Abstract
An ion removal device based on electrochemical and photoelectrochemical methods, and the application of energy conversion and storage are provided. In the ion removal process based on the electrochemical and photoelectrochemical fluidization battery device, the positive active material in the flow battery is the positive pole of device, the negative active material in the fluid battery is the negative pole of the device, and the salt solution is the electrolyte in the middle stream. The positive and negative active materials include organic materials such as 4-hydroxy-piperidinol oxide, riboflavin sodium phosphate or methyl viologen, which have the advantages of low raw material cost, environmental friendliness, high sustainability, excellent electrochemical performance, high specific capacity and good cycle stability etc. The electrolyte can be separated from the positive and negative active liquid flow materials according to the fixed sequence of self-assembly of fluid battery mold.
