Electrochemical Conversion of Salinity Gradient Energy via Molybdenum Disulfide Electrode

The energy generated when sea water meets river water is called salinity gradient energy. At present, the main methods to extract salinity gradient energy are pressure-retarded osmosis, reverse electrodialysis and capacitive mixing technology. The selection of electrode materials has always been the focus of capacitive mixing technology. Here we report a device assembled based on capacitive mixing technology with molybdenum disulfide as anode and activated carbon as cathode. The energy density of the device is 6.12 J g −1 , which shows that it has application prospects in the development of renewable energy.
