Pure Lithium Proposes Innovation in Lithium Metal and Battery Production
Pure Lithium, a company based in the United States, has recently submitted a patent application for a novel method of producing pure lithium metal and manufacturing lithium batteries in a vertically integrated process. This application, filed on March 21, 2023, introduces a technique that involves the electrolysis of aqueous lithium salt solutions through lithium ion selective membranes to create highly pure lithium metal electrodes.
The process, designed to operate at constant current densities between about 10 mA/cm^2 and about 50 mA/cm^2 for durations ranging from about 1 minute to about 60 minutes, is conducted under a blanketing atmosphere devoid of components reactive to lithium. This innovative approach aims to streamline the fabrication of lithium metal electrodes and integrate them directly into the production of lithium metal batteries within the same facility.
The patent application, numbered 202317018934 A, covers several international classifications, including C25D 3/54, C25D 3/66, H01M 4/04, H01M 4/13, and H01M 4/38, indicating its relevance across various aspects of lithium metal production and battery manufacturing.
