Latest Patents

One of her latest patents focuses on carbonate electrolytes for lithium-ion batteries. This innovation provides electrolytes that extend the cycle life of fast-charging lithium-ion batteries. The electrolytes are based on fluoroethylene carbonate (FEC) and/or vinylene carbonate (VC) as the cyclic carbonate component, and possibly on ethyl acetate (EA) and/or ethyl methyl carbonate (EMC) as the linear component. These proposed electrolytes can extend the cycle life by factors of two or more, as indicated by several complementary measurements.

Another significant patent involves cell stack assembly systems. This invention includes methods, stacks, and electrochemical cells where the cell separator is surface-treated prior to attachment to the electrode(s). This process creates binding sites on the cell separator, enhancing its binding to the electrode(s) electrostatically. The cell separators may be attached to the electrodes by cold press lamination, stabilizing the assembly electrostatically and forming flexible and durable electrode stacks. The produced stacks can be utilized in electrochemical cells and other types of energy storage devices.
