Latest Patents

Yabuki holds a patent for a method of recovering lithium from batteries, specifically lithium-ion secondary batteries. The patent describes a process where the lithium-containing member of the battery is dissolved using an acidic liquid. An alkaline material is then added to the resulting lithium solution, transforming any dissolved transition metals into metal hydroxide precipitates. These precipitates are separated from the lithium solution, which is subsequently dried to obtain a solid containing lithium. The lithium is then eluted from this solid using a non-aqueous solvent, with retrieval accomplished through a cation exchanger. This innovative method not only enhances lithium recovery but also promotes environmental sustainability.
