This new invention could make today’s heavy electric vehicle batteries lighter, safer and increase their range. The researchers behind the technology believe it is also ideal for use in aviation, space travel, drones and shipping.
Car manufacturers and others who need light, safe, powerful batteries are eager to adopt lithium-sulphur (Li-S) batteries. Not only do they store more energy, and are safer and faster to charge than today’s lithium-ion batteries – they’re cheaper to make, too.
It’s just that these next-generation wonder batteries have one big problem: They wear out very quickly. The reason is that they suffer from what is called the shuttle effect.

Tests by Önder Tekinalp and his colleagues show that lithium-sulphur (Li-S) batteries with the ultrathin HiSep-II coating can increase the number of charge cycles from 200 to 1,000. This increases the battery life by a factor of five. (Photo Credit: Sølvi W. Normannsen)
