1,000-Cycle Lithium-Sulfur Battery Could Enhance EV Ranges

A new biologically inspired battery membrane from the University of Michigan has enabled a battery with five times the capacity of the industry-standard Li-ion design to run for the 1,000-plus cycles needed to power an EV. Watch this video to see how a network of recycled aramid nanofibers can enable lithium-sulfur batteries to prolong their cycle life.

“Inspired by biological ion channels, we engineered highways for lithium ions where lithium polysulfides cannot pass the tolls,” said Ahmet Emre , a postdoctoral researcher in chemical engineering and co-first author of the paper in Nature Communications.
