Title: Innovations of Chun-hua Chen in Lithium Battery Technology
Introduction
Chun-hua Chen is a notable inventor based in Westmont, IL, who has made significant contributions to the field of lithium battery technology. With a total of 2 patents, his work focuses on enhancing the safety and performance of lithium-ion batteries.
Latest Patents
One of his latest patents is for a lithium-ion battery with improved safety. This invention utilizes one or more additives in the battery electrolyte solution, where a lithium salt is dissolved in an organic solvent, which may contain propylene carbonate. For instance, a blend of 2 wt % triphenyl phosphate (TPP), 1 wt % diphenyl monobutyl phosphate (DMP), and 2 wt % vinyl ethylene carbonate additives has been found to significantly enhance the safety and performance of Li-ion batteries using a LiPF salt in EC/DEC electrolyte solvent. This invention relates to both the use of individual additives and blends of additives at concentrations of 1 to 4 wt % in the lithium battery electrolyte. The additives suppress gas evolution in the cell, passivate the graphite electrode, and protect it from exfoliating in the presence of propylene carbonate solvents in the electrolyte, while also retarding flames in the lithium batteries.
Another significant patent by Chun-hua Chen involves lithium-titanium-oxide anodes for lithium batteries. This invention features a spinel-type structure with the general formula Li[T,Li,M]O, for 0
