Latest Patents

Among his latest patents, two remarkable inventions stand out. The first is a **Relithiation process for direct regeneration of cathode materials from spent lithium-ion batteries**. This method outlines a process where a lithium precursor is dissolved in a polyhydric alcohol, creating a solution for dispersion of degraded cathode material. By mechanically stirring this mixture and heat treating it, Bai's method successfully intercalates lithium back into the degraded materials, allowing for the recovery of valuable battery components.

The second patent, **Direct regeneration of lithium ion cathodes by ionothermal relithiation**, describes a sophisticated technique for relithiating catheodes. This method involves mixing delithiated cathode materials with lithium salt and ionic liquid, followed by heating to facilitate relithiation. The ionic liquid is then separated from the regenerated cathode material, which can be further refined to enhance its properties. This patent showcases Bai's commitment to advancing battery technology and improving resource efficiency.
