His work focuses on developing novel microporous membranes that enhance the performance and safety of batteries.

Latest Patents

Summey's latest patents include advancements in membranes, specifically calendered microporous membranes and battery separators. These innovations provide improved microporous single or multilayer battery separator membranes, which are crucial for the efficiency and safety of batteries. The inventive process involves machine direction stretching followed by transverse direction stretching, along with a calendering step. This process reduces the thickness and percent porosity of the multilayer microporous membrane in a controlled manner. Additionally, it enhances the transverse direction tensile strength of the membranes. A notable embodiment of his work produces a thin multilayer microporous membrane that is easily coated with polymeric-ceramic coatings. This membrane exhibits excellent mechanical strength due to its polypropylene layers and a thermal shutdown function attributed to its polyethylene layers. The ratio of the thickness of these layers can be tailored to achieve a balance between mechanical strength and thermal shutdown properties.
