Imagine having access to a battery, which has the potential to power your phone for five continuous days, or enable an electric vehicle to drive more than 1000km without needing to “refuel”.

Monash University researchers are on the brink of commercialising the world’s most efficient lithium-sulphur (Li-S) battery, which could outperform current market leaders by more than 4X, and power Australia and other global markets well into the future.

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 ...
