Making a prototype lithium-ion battery

Argonne chemical engineer Andrew Jansen lines up positive and negative electrodes on a machine called a winder. The two electrodes will be wound together with a separator to create a structure called a “jellyroll,” which is then used to make a prototype lithium-ion battery.

 

Argonne is one of several research institutions that form an integral part of the Joint Center for Energy Storage Research, a public-private partnership that aims to overcome critical scientific and technical barriers and create new breakthrough energy storage technologies.
