Latest Patents

Among his latest patents is a diaphragm and high-voltage battery comprising the same. This invention features a diaphragm that includes a modification layer coated on the surface of inorganic ceramic particles. This layer effectively adsorbs transition metal ions from electrode materials, preventing the formation of transition metal precipitates on the negative electrode. As a result, the safety, rate performance, and cycle performance of the battery are significantly improved. Importantly, the modification layer does not adversely affect the internal resistance of the battery, thus maintaining its performance under various conditions.

Another notable patent is the non-woven fabric separation membrane and its preparation method. This separation membrane consists of closely connected fibers enhanced by a modifier, which greatly improves both the tensile and puncture strength of the membrane. The grafting of modifier molecules on the fiber surfaces enhances the wettability for electrolyte solutions, leading to improved ionic conductivity and rate performance of the battery. The inclusion of Ti or Zr metal in the modifier molecule effectively attracts electrolyte anions, reducing battery polarization and further enhancing performance.
