Holistic Cell Design by Berkeley Lab Scientists Leads to High-Performance, Long Cycle-Life Lithium-Sulfur Battery

Battery could find use in mobile applications, and eventually, electric vehicles with 300-mile range

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory  (Berkeley Lab) have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries, and that lasts for more than 1,500 cycles of charge-discharge with minimal decay of the battery’s capacity. This is the longest cycle life reported so far for any lithium-sulfur battery.
