Latest Patents

Xu’s listed patent is “High-selectivity hydrophilic electrode for extracting lithium and preparation method thereof.” The disclosure describes modifying an electrode’s active material with polydopamine, which preferentially accumulates and transports lithium ions to help limit impurity ions and improve lithium selectivity.

The preparation method also blends a hydroxyl-containing hydrophilic polymer into the electrode slurry to improve the hydrophilicity of the polyvinylidene fluoride binder. Inorganic-salt pore formation and a low-temperature-to-high-temperature drying process are used to create a porous, microcracked electrode structure that supports solution mass transfer. The disclosure presents the method as practical, environmentally friendly, low-cost, and suitable for industrial production. Xu is listed with 1 patent.
