SALT SOLUTION-BASED PERFORMANCE-ENHANCED WATER VOLTAIC POWER GENERATOR, MANUFACTURING METHOD THEREFOR, AND APPLICATION THEREOF

摘要

A salt solution-based performance-enhanced water voltaic power generator comprises a functional film (1) having a conductive nanomaterial layer and electrodes at two ends of the functional film. The functional film comprises a hydrophobic region and a hydrophilic region at two ends thereof. The conductive nanomaterial layer has conductive networks formed by a conductive nanomaterial in both the hydrophobic region and the hydrophilic region. An upper electrode (2) and a lower electrode (3) are provided in the hydrophobic region (1a) and the hydrophilic region (1b), respectively. A portion of the hydrophilic region provided with the lower electrode is always immersed in an aqueous solution, and a portion of the hydrophobic region provided with the upper electrode is always exposed from a surface of the aqueous solution. During an evaporation process of water in a region between the upper electrode and the lower electrode, a solute concentration gradient constructed in the hydrophilic region enables a concentration difference diffusion potential to be formed between the two electrodes. The water voltaic power generator effectively utilizes aqueous solutions having different salinities to generate power continuously, and is applicable as a power supply for supplying power to electronic/electrical devices. Further disclosed are a manufacturing method for a water voltaic power generator, and a water voltaic power generator-based integrated electricity generation system.
