Biography

Professor Whitacre examines the materials science of synthesizing, characterizing, and implementing promising materials and device architectures for energy storage and generation technologies such as Li-ion batteries, fuel cells, and photovoltaics. He will concurrently be addressing the policy implications involved with selecting and implementing these renewable technologies. Other research topics include hybrid power systems for distributed and mobile platforms, high throughput materials selection methods, and ultra fast laser modification of materials for solid-state electrochemical devices. Whitacre has authored or co-authored over 60 peer review papers and is an inventor on over 30 patents that are issued or pending. He has numerous honors to his name, including the 2014 Caltech/Resnick Sustainability Institute Resonate Award, was listed as one of the top 25 Eco-Innovators in the world by Fortune Magazine in 2014, and was the 2015 winner of the $500,000 Lemelson-MIT Prize for Innovation.

Is Elon Musk Right That Cybertruck Contained Explosion? What Experts Say

Newsweek  online

2025-01-03

Jay Whitacre, a trustee professor in energy at Carnegie Mellon University, spoke to Newsweek about the mechanics of the explosion.

"My understanding of 'containing the explosion' here is that the sides of the truck did not blow out, and so all the explosive force went vertically as opposed to in all directions, thus partially containing the blast," Whitacre said. "Looking at the state of the truck, this seems to be what happened."

"To meet the increasing demand and economic pressures, lithium-ion battery manufacturers must make a fundamental shift in their approach to quality control. Titan's cell-level inspection technology offers a step-change improvement compared to the use of only traditional electrical methods of inspection," said Jay Whitacre. "As part of my research at Carnegie Mellon University my team evaluated Titan's ultrasound technology alongside OCV, DCIR and impedance spectroscopy. Titan's technology offers a new level of defect detection which can enable process optimization through better predictability and control."

Reevaluating the stability of the PEO-based solid-state electrolytes for high voltage solid-state batteries

Journal of Energy Storage

2023

This work shows how PEO-based solid state-electrolyte materials can be more stable than commonly expected when used with some types of high voltage cathode materials. Potentiodynamic and galvanostatic tests were performed in test cells using PEO electrolyte layers with either LiNixMnyCozO2 or LiCoO2 cathode materials.
