Latest Patents

Jinli Li holds a patent for a preparation method of lithium hydroxide. This method involves several steps: first, coprecipitating a lithium extraction mother solution of salt lake brine with an aluminum salt solution and a sodium hydroxide solution. This is followed by aging, solid-liquid separation, washing, and drying to obtain lithium aluminum hydrotalcite. The process continues with acidifying the lithium aluminum hydrotalcite to produce a lithium aluminate solution. Subsequently, nanofiltration is performed for lithium-aluminum separation, and primary concentration is achieved through reverse osmosis to obtain a primary concentrated lithium-rich solution. The method further includes deeply removing aluminum from the lithium-rich solution and performing bipolar membrane electrodialysis to obtain a secondary concentrated lithium-rich solution. Finally, the secondary concentrated lithium-rich solution is evaporated for concentration to yield lithium hydroxide.
