Argonne’s Upgraded APS will Enable Advances in Battery Design
Argonne is building two new research tools. One is an upgrade of the Advanced Photon Source (APS), while the other is an addition to the Argonne Leadership Computing Facility — Aurora. Together, the two aim to transform how science is carried out — uncovering the secrets of new materials, seeing the evolution of the universe, mapping the human brain, and creating new breakthroughs. Watch this video to see Argonne physicist Luxi Li discuss how the upgraded APS will enable advances in battery design.

00:00:01 [Music] I'm Lucy Lee I'm a physicist and beam line scientist working for Argon National Laboratory my research is focusing on energy storage systems mainly focus on rechargeable lithium iron batteries and this is a material that is so widely used for portable Electronics like cellphones laptops and also electric vehicle so to drive the
00:00:29 material development there are several important criterias for example high energy density fast charge discharge rate and long lifespan and of course promoted safety take cell phone as an example so higher power density means your cell phone can work for longer hours or we can reduce the weight by half for the fast charging discharging rate imagine you have a cell phone that
00:00:55 only takes two minutes to fully charge and then it will last for a day or two that would be perfect battery materials consist of millions of nanop particles the size of a battery particle is about 100th of a human hair or even smaller x-ray has such high penetration power so that enables us to study the internal structure of battery particles under its working condition non destructively we
00:01:24 have the advanced Photon source which has so many extra beam lines that allows for x-ray science research after the aps upgrade the brightness of the X-ray is going to be a few hundred times brighter than the current condition think about today's APS it's like taking pictures at night so to get a decent picture with sufficient contrast it may take a couple of hours of exposure but after the aps
00:01:53 upgrade it's going to be like taking pictures in the daylight it's very bright and only takes a TENS of a second for exposure to get decent picture within 2 hours we're going to have thousands of pictures collected in this way we will need Super computing power to help with the data analysis with apsu upgrade together with Aurora we're going to bring our research to a new level
