Latest Patents

One of her latest patents is titled "Systems and methods of preparing lithium sulfur electrode using sacrificial template." This invention addresses the challenges associated with lithium-sulfur batteries by preventing the coarsening of sulfur during the melt-diffusion processing of cathodes. By adding a lithium salt, such as LiTFSI, prior to the melt-diffusion process, she enables the creation of a sulfur electrode with a high concentration of triple-phase junctions for electrochemical reactions. This innovation achieves approximately 60-70% utilization of the theoretical capacity of sulfur at high loadings, significantly improving the performance of Li-S batteries.

Another notable patent is the "Gravity induced flow cell." This invention features a flow cell design that includes first and second reservoirs containing a flowable redox electrode. A membrane separates the charged and discharged materials, while an energy-extraction region allows for charge transfer. The unique structure enables the alteration of the flow cell's orientation, allowing gravity to induce the flow of the redox electrode, thereby varying the flow rate and power delivered during discharge.
