Abstract
Researchers at the University of Central Florida have developed the following technologies that eliminate the future risk of losing limited supplies of cobalt (Co) and nickel (Ni) and provide a way to sustainably produce competitively priced batteries with high energy density.
- Technology 2022-013 is a Co- and Ni-free lithium-ion cathode that offers good thermal stability and can achieve a high cell voltage and specific capacity. Its performance is comparable to or exceeds current Li(NiCoMn)O2 cathodes. This new cathode chemistry eliminates metal supply issue concerns. It also lowers the cost of batteries, particularly for electric vehicle (EV) applications, where the battery cost is a significant amount of the total cost.
- Technology 2023-026 consists of new active materials for lithium-ion secondary batteries. The materials enable high discharge capacity, low cost, and ease of capacity estimation. They show a high capacity when the ratio of powder x-ray diffraction peak intensities originated from an orthorhombic or monoclinic lithium manganese composite oxide (LiMnO2)-based layered structure; LiAlO2 with R-3m and Li2MnO3 with C2/m is in a specific range.
