Title: Ta-Hua Yu: Innovator in Battery Separator Technology

Introduction

Ta-Hua Yu is a prominent inventor based in Nanuet, NY (US), known for his significant contributions to battery technology. He holds a total of 4 patents, showcasing his expertise and innovative spirit in the field.

Latest Patents

Among his latest patents, Ta-Hua Yu has developed a microporous battery separator that features a first co-extruded multilayered portion and a second co-extruded multilayered portion. These two portions are bonded together, creating a highly effective battery separator. In a preferred embodiment, the separator consists of two substantially identical multilayered portions bonded face-to-face. Each multilayered portion includes at least one strength layer and at least one shutdown layer. The methods for producing these battery separators involve extruding a tubular multilayered film, collapsing it onto itself to form a precursor, and then bonding and annealing it before stretching to create the final microporous multilayer battery separator. Additionally, he has patented a high melt integrity battery separator specifically designed for lithium-ion batteries. This separator is made from a nonwoven flat sheet material that possesses high-temperature melt integrity, combined with a microporous membrane that has low-temperature shutdown properties. An adhesive bonds the nonwoven flat sheet to the microporous membrane, which is designed to swell upon contact with an electrolyte.
