Her work focuses on developing methods for producing clean battery materials, which are essential for sustainable energy solutions.

Latest Patents

One of her latest patents is titled "Recovery of contaminant free battery materials." This invention provides a method for producing clean black mass, anode, or cathode for subsequent recycling. The method involves subjecting an intact battery to a shredding process to produce an aggregate, with the smallest particle generated being between 2.5 percent and 40 percent of the original battery size. Additionally, she has developed a shredder designed to minimize the aggregation of whole batteries, featuring a shaft with a plurality of teeth disposed at specific angles.

Another notable patent is "Stabilized lithium metal oxide electrode material and method of preparation." This invention describes a stabilized lithium metal oxide cathode material comprising microparticles of lithium metal oxide. The individual particles consist of a core of lithium metal oxide surrounded by a coating of a different lithium metal oxide. The preparation involves a three-stage process that includes coprecipitating precursor metal hydroxide core particles and calcining the resulting coated precursor particles with lithium hydroxide.
