The present invention belongs to the technical field of battery materials, and provides a lithium-rich lithium ferrite lithium supplementing agent, a synthesis method and a use thereof. In the synthesis method, a solid electrolyte, conductive carbon and elemental sulfur are mixed and subjected to low-temperature heat treatment to form a composite mixture, and then the composite mixture is secondarily mixed with lithium-rich lithium ferrite and subjected to low-temperature heat treatment to form a mixed coating layer on the lithium-rich lithium ferrite, thereby obtaining the lithium-rich lithium ferrite lithium supplementing agent. Sulfur in the mixed coating layer can absorb the surface oxygen released during the charging process of the lithium-rich lithium ferrite, thereby reducing gas generation. The solid electrolyte and the conductive carbon can form an ionic and electronic conductive network, avoiding the difficulty of Li+ extraction and the decrease of lithium supplementing capacity caused by too thick sulfur coating. At the same time, the low-temperature heat treatment causes the elemental sulfur to melt, which can play a role in dispersion and adhesion, realizing the uniform dispersion of the solid electrolyte and the conductive carbon and the effective coating of the composite mixture, which is beneficial to improving the binding property and compatibility. The obtained mixed coating layer can effectively improve the air stability of the lithium supplementing agent.

A system utilizes an electrochemical reactor to convert salt into acid and base products. The salt is sourced from seawater, brine or another aqueous salt feedstock solution that typically also includes divalent ions. A small (slipstream) portion of the base product generated by the electrochemical reactor is fed back to a chemical precipitator where it is utilized to increase a pH level of the aqueous salt feedstock solution above a precipitation level of at least some the divalent ions, thereby causing precipitation of the divalent ions into insoluble solids. The insoluble solids are then filtered or otherwise separated / removed from the remaining supernatant solution (i.e., the aqueous salt / base solution formed by a mixture of the residual aqueous salt feedstock solution and base product). The supernatant solution is then supplied to the electrochemical reactor for conversion of its salt into additional acid and base product.
