SURFACE-TREATED NEGATIVE ELECTRODES FOR SODIUM-ION BATTERIES

Resumen de: US20260321625A1

0000 Provided is a surface treatment process to dictate the surface chemistry of a negative electrode for sodium-ion batteries. In particular, the surface treatment process eliminates and, in some instances, replaces the native oxide of the alloy-type negative electrode material with more favorable amounts of species, such as PbCl<2 >or PbF<2>, derived from the acid etch composition. The surface treatment process may include a washing step with a solution composition tailored to the surface chemistry after the acid etching step. The initial Coulombic efficiency and utilization of the active material in the surface-treated negative electrode is above 90%, relative to the theoretical maximum, for both metrics. Specific classes of solvents need to be avoided and used to enable the surface-treated negative electrode. These results indicate that engineering the surface chemistry of an alloy material enables a new class of negative electrode active materials for sodium-ion batteries.
