Defining the
Future of the
Public Research
University
Batteries in the lab are charged and
discharged at different current densities
and cut-off voltages-to be evaluated
on energy density and cycling efficiency.
The information gained is critical for
scientists in correlating the structures of
the materials with the electrochemical
performance of the batteries.
UC San Diego
A Battery of Solutions
To help ensure a low-carbon future, batteries will need to do more than
charge faster, last longer and cost less-they will need to perform at the high
voltages electric cars require. Two UC San Diego researchers-nanoengineer
Shirley Meng, Ph.D., and physicist Oleg Shpyrko, Ph.D.-are collaborating to
address the challenge. Their work in the new Sustainable Power and Energy
Center combines Meng's expertise in battery research with Shpyrko's X-ray
imaging techniques to provide insights-at the nanoscale-on what happens
inside a battery while it operates in real time. Ultimately, their findings will shape
how battery developers design high-voltage lithium-ion batteries to reduce
greenhouse emissions and the carbon footprint of vehicle transportation.

The work at the Sustainable Power and Energy Center to better understand and
protect the planet is also aligned with the sustainable operations on campus.
UC San Diego's renowned microgrid serves as the real-world test bed for the
researchers to explore their green and advanced energy solutions.
