Miltec UV International and its partners, Oak Ridge National Laboratory (ORNL) and Argonne National Laboratory (ANL) undertook this project to demonstrate the use of UV curable binder to replace conventional solvent based binders such as PVDF as a means of reducing the manufacturing cost of Lithium ion battery (LIB) electrodes. The project involved an iterative Research and Development (R&D) effort: making coin cells and pouch cells from electrodes made with varying UV chemistries and active materials, followed by testing and analyses, then by adjustments in UV chemistry, mixing, coating, and UV curing to produce layered pouch cells at high processing speeds with performance equal or greater than that of a conventional PVDF cell. The effort focused on cathodes made with UV curable binders and multiple active cathode materials such as NMC, NCA, Sulfur, and LMO and anodes made with LTO. A primary objective of the project is to provide performance data sufficient for Lithium ion battery manufacturers to commit to the first steps of making their own HEV, PHEV and/or EV Lithium ion batteries with a UV process. In addition, the project successfully demonstrated coating and UV curing a cathode layer on top of an existing UV cathode layer to produce a thicker high energy cathode with good porosity and no discontinuity between layers. It also demonstrated the potential advantages of one layer of a power loading with a second layer of an energy loading.
