February 17, 2026, Hadley McCollester
Batteries are part of our everyday lives, but not many of us think about how they work or what they are made of. For researchers at the Lab for Materials Properties and Structures, these questions are a full time job. Golareh Jalilvand and her team at USC's Molinaroli College of Engineering and Computing are dedicated to testing alternative battery materials such as lithium iron phosphate that will help make batteries a part of the country's sustainable future. This documentary explains why for batteries, it's what's inside that counts.
