Overview

At UL, we are at the intersection between chemistry and electricity. Our global teams are constantly developing new ways to help the world benefit from Sustainable Energy and working with the industry leaders, governments and other organizations to facilitate the safe innovation of the processes, technologies and products that are transforming the energy industry.

 

We are spearheading research and updating standards to help ensure the safe commercialization of state-of-the-art batteries. We are developing tests and other methods to measure and enhance the efficiency and reliability of photovoltaics. We are conducting experiments and facilitating progress in wind energy generation. And we are creating new ways to anticipate and mitigate safety risks related to the smart grid. UL is safeguarding these and other emerging technologies to help address rising energy costs, inefficient electrical infrastructure and environmental impact — the forces that are spurring progress globally in energy generation, distribution,

management and usage.

Mahmood Tabaddor, Ph.D.
Research Manager and Distinguished Member of Technical Staff

Dr. Mahmood Tabaddor leads the Predictive Modeling Global Center of Excellence. He received his master of science in mechanical engineering from the University of Michigan and his doctorate in engineering mechanics from Virginia Polytechnic Institute and State University. He has extensive experience in applying high-performance computing (HPC) tools during his tenure at Bell Labs and DaimlerChrysler. At UL, Dr. Tabaddor is responsible for developing and executing strategies that would further the use of HPC tools in advancing safety science. He also employs a risk management framework for analyzing hazards related to fire and electrical safety.

“To enable the safe commercialization of rapidly evolving technologies such as lithium-ion cells, it is important that consensus-based safety standards reflect the state of technical knowledge. This can only happen through open cooperation amongst a range of stakeholders.”

Alvin Wu
Research Engineer

Mr. Alvin Wu specializes in lithium-ion battery (LIB) research in Taiwan. Since joining UL in 2005, his projects have included internal short-circuit test method development, the investigation of LIB thermal runaway mechanisms and an aging effect study on the safety performance of lithium-ion batteries. Before working at UL, Mr. Wu was a research engineer at Taiwan YUASA Co., focusing on the fundamental electrochemistry study and battery design. He received his masters of science in chemical engineering from National Taiwan University in 2000.

“Our research into the effects of aging on lithium-ion batteries is predicated on our findings that after 25% of its designed cycle life, it can become increasingly difficult to predict the behavior of these energetic devices.”
