1,000-Cycle Lithium-Sulfur Battery Could Quintuple Electric Vehicle Ranges

A new biologically inspired battery membrane has enabled a battery with five times the capacity of the industry-standard lithium ion design to run for the thousand-plus cycles needed to power an electric car. A network of aramid nanofibers, recycled from Kevlar, can enable lithium-sulfur batteries to overcome their Achilles heel of cycle life — the number of times it can be charged and discharged — a University of Michigan team has shown.
