Abstract: A bias-free driven ion-based photoelectrochemical wastewater treatment system and method is disclosed. Through an ion-coupled photogenerated electron-assisted photocatalytic oxidation-reduction pathway, the system achieves efficient treatment of high-salinity wastewater. The system employs electron-ion receptor materials as the counter electrode, providing reaction sites to drive the coupling of photogenerated electrons and cation transfer. Additionally, the voltage generated by the system directly drives hole oxidation to produce strong oxidizing free radicals. Furthermore, this ion-based photoelectrochemical system demonstrates excellent degradation performance in high-concentration chloride media. This indicates that, in addition to cations (such as Na+) helping to accelerate the electron transfer rate, the presence of Cl? further enables efficient and sustainable wastewater treatment.

Abstract: The present application relates to an electrode sheet, a battery cell and a battery. The electrode sheet includes a current collector and a protective layer. The current collector includes a coated region provided with an active material layer and an uncoated region without being provided with the active material layer. The protective layer is provided on at least a part of a surface of the uncoated region, and has a porosity of 0% to 95%. For the electrode sheet according to the present application, by providing the current collector with the protective layer, the contact resistance may be increased when the electrode sheet is short-circuited, and the discharge power and the thermal runaway probability of the battery cell may be reduced when the battery cell is internally short-circuited, thereby improving the safety performance of the battery cell.
