Our client’s research focuses on advancing lithium-ion battery technology, core components in electric vehicles, aerospace systems, and large-scale energy grids, by improving their resilience in extreme environments and enhancing their safety, efficiency, and longevity.

In support of his petition, we highlighted his impressive academic record: 8 peer-reviewed journal articles (including 1 as first author), 306 citations, 4 completed peer reviews, and a patent application, demonstrating both the scholarly value and practical impact of his work.
His efforts have garnered strong recognition from fellow experts in the field. One recommender wrote:

Given the crucial applications of these batteries in industries such as aerospace, it is evident that [client’s] work holds significant value in the field, making him an indispensable presence in research.”
The successful approval of his NIW petition affirms the real-world relevance and national value of his research. At NAILG, we are proud to have played a role in this important step forward and look forward to seeing our client’s continued contributions to energy innovation and sustainability.
