Researchers at UNT create environmentally friendly, more efficient replacement for lithium ion batteries

UNT researchers create Lithium-ion alternative

Lithium-ion batteries power some of the most used electronics, including smartphones, laptops, tablets and electric cars. Researchers at the University of North Texas College of Engineering have developed a higher-power, longer-life, environmentally-friendly lithium-sulfur alternative that could replace the lithium-ion battery.

Wonbong Choi, professor of materials science and engineering, collaborated with three of his doctoral students – Juhong Park, Mumukshu D. Patel and Eunho Cha – as well as Dr. Vish Prasad from UNT Mechanical and Energy Engineering and two other local scientists – to create the battery. The researchers have applied for a patent through UNT and are working towards potential prototyping and production. Read more.

UNT researchers use first-of-its kind process to develop wear and corrosion resistant alloys

UNT researchers to develop wear and corrosion resistant alloys

What if materials could be tested at the atomic level to determine exactly how and why they break down and then be improved to create ultra-high performance alloys? Researchers at UNT’s College of Engineering have done just that.

The material tested was a complex alloy composed of six different elements and a unique microstructure with crystalline phases in a glassy matrix. The alloy was tested simultaneously for bulk wear and bulk corrosion resistance.

Aditya Ayyagari, a recent Department of Materials Science and Engineering doctoral graduate is the lead author on the study, which was partly supported by a National Science Foundation grant earned by Sundeep Mukherjee, associate professor and corresponding author on the paper. Read more.
