Abstract: An apparatus, also named transfer box or TB, for conveying an anode assembly outside of an electrolyte cell is described. An apparatus, also named cell preheater lifting beam or CPLB, for conveying an anode assembly or a cell pre-heater outside of an electrolyte cell is also disclosed. TB and CPLB are conjointly used for starting up the electrolytic cell or for replacing a spent anode assembly while maintaining the production of non-ferrous metal, such as aluminum or aluminium. The thermal insulation of the TB allows maintaining the anode temperature homogeneity and preventing thermal shocks when introducing the inert anodes into the hot electrolytic bath. TN and CPLB allow accurate positioning of anode assemblies or cell-preheaters over the electrolysis cell before achieving mechanical and electrical connections of the anode assembly or the cell pre-heater to the electrolysis cell. Several related methods for the operation of an electrolytic cell are also disclosed.

Abstract: Methods and systems of the present disclosure are generally directed to switching operation of one or more electrochemical cells of an electrowinning plant between a charge mode and a discharge mode. In the charge mode, the one or more electrochemical cells may reduce metal from an oxidized state to a zero valence state with a first electric current applied across the one or more electrochemical cells. In the discharge mode, the one or more electrochemical cells may oxidize at least some of the metal from the zero valence state to the oxidized state to generate a second electric current, oppositely charged relative to the first electric current, to generate electricity (e.g., for delivery to the grid). Operation of the one or more electrochemical cells of the electrowinning plant may be selectively changed between the charge mode and the discharge mode based on, for example, availability/cost of electricity from the grid.

Abstract: In this disclosure, a process of recycling acid, base and the salt reagents required in the Li recovery process is introduced. A membrane electrolysis cell which incorporates an oxygen depolarized cathode is implemented to generate the required chemicals onsite. The system can utilize a portion of the salar brine or other lithium-containing brine or solid waste to generate hydrochloric or sulfuric acid, sodium hydroxide and carbonate salts. Simultaneous generation of acid and base allows for taking advantage of both chemicals during the conventional Li recovery from brines and mineral rocks. The desalinated water can also be used for the washing steps on the recovery process or returned into the evaporation ponds. The method also can be used for the direct conversion of lithium salts to the high value LiOH product. The method does not produce any solid effluent which makes it easy-to-adopt for use in existing industrial Li recovery plants.

Abstract: Disclosed are an electrolytic reduction system of a vanadium electrolyte and a method for producing the electrolyte. The electrolytic reduction system includes a separating device and an electrolytic tank. The separating device is configured to separate a mixture consisting of a vanadium pentoxide (V2O5) solid and a sulfate acid solution, thereby obtaining a vanadium solution from a liquid discharging port of the separating device and a vanadium solid from a solid discharging port. The vanadium solution includes pentavalent vanadium ions. The electrolytic tank connects to the liquid discharging port of the separating device to contain the vanadium solution. In the method for producing the vanadium electrolyte, other chemical reagents are unnecessarily to be added into the mixture, and the vanadium solution is subjected to an electrolytic reduction process, such that the pentavalent vanadium ions are reduced to tetravalent vanadium ions and trivalent vanadium ions in the electrolytic tank.

Abstract: Disclosure relates to an electrochemical lithium recovery system, and the electrochemical lithium recovery system is characterized by having a first flow electrode module that selectively extracts lithium ions from an object solution containing a waste battery active material by electrical attraction, and a second flow electrode module recovering the lithium ions extracted by the first flow electrode module, by the electric repulsive force. Accordingly, the electrochemical lithium recovery system does not require a high temperature treatment process, does not require a large amount of chemicals, and can ensure high recovery efficiency.
