Researchers from Australia have claimed that they have developed the world’s most efficient lithium-sulfur (Li-S) battery.
It is capable of powering a smartphone for five continuous days, the equivalent of an electric car being able to drive a distance of over 1,000 km.
Li-S batteries are considered as the successors of the Lithium-ion (Li-ion) batteries because of their lower cost of production, energy efficiency and improved safety.
Their cost of production is lower because sulphur is abundantly available.
