Looking for the next leap in rechargeable batteries

USC researchers may have just found a solution for one of the biggest stumbling blocks to the next wave of rechargeable batteries — small enough for cellphones and powerful enough for cars.

USC researchers may have just found a solution for one of the biggest stumbling blocks to the next wave of rechargeable batteries — small enough for cellphones and powerful enough for cars.

In a paper published in the January issue of the Journal of the Electrochemical Society, Sri Narayan and Derek Moy of the USC Loker Hydrocarbon Research Institute outline how they developed an alteration to the lithium-sulfur battery that could make it more than competitive with the industry standard lithium-ion battery.

The lithium-sulfur battery, long thought to be better at energy storage capacity than its more popular lithium-ion counterpart, was hampered by its short cycle life. Currently the lithium-sulfur battery can be recharged 50 to 100 times — impractical as an alternative energy source compared to 1,000 times for many rechargeable batteries on the market today.
