To provide a method of manufacturing a lithium-ion secondary battery having stable charge characteristics and lifetime characteristics. A positive electrode is subjected to an electrochemical reaction in a large amount of electrolytic solution in advance before a secondary battery is completed. In this manner, the positive electrode can have stability. The use of the positive electrode enables manufacture of a highly reliable secondary battery. Similarly, a negative electrode is subjected to an electrochemical reaction in a large amount of electrolytic solution in advance. The use of the negative electrode enables manufacture of a highly reliable secondary battery.

A method of regenerating a platinum bath by flow reaction, the method comprising the successive steps of: drawing off fluid from the platinum bath by means of a draw-off flow; complexing platinum by mixing together the draw-off flow and a regeneration solution flow containing platinum, mixing taking place in an intensified reactor; and feeding the platinum bath with the mixture resulting from the platinum complexing step, by means of a regenerated bath flow; all of these steps being performed as a continuous flow.

A plating apparatus includes a processing bath configured to store a processing liquid therein, a transporter configured to immerse a substrate holder, holding a substrate, in the processing liquid, raise the substrate holder out of the processing bath, and transport the substrate holder in a horizontal direction, and a gas flow generator configured to generate a clean gas flow forward of the substrate with respect to a direction in which the substrate holder is transported. The transporter moves the gas flow generator together with the substrate holder in the horizontal direction while transporting the substrate holder in the horizontal direction.

A decoupled plating system is provided for producing lithium. In a general embodiment, the present disclosure provides a feed tank configured to supply a lithium-rich aqueous electrolyte stream, a plating tank that is configured to receive an organic electrolyte and plate out lithium metal from that organic electrolyte, and one or more lithium replenishment cells configured to receive both electrolytes, keep them separated, and selectively move lithium ions from the aqueous electrolyte into the spent organic electrolyte stream. The present system and process can advantageously reduce operating costs and/or improve energy efficiency in production of lithium metal and associated products.
