Researchers have developed a new battery they claim can power a phone for five continuous days, or allow an electric vehicle to travel more than 1,000 km without needing to recharge.

The groundbreaking energy storage is made possible by ditching lithium-ion batteries – used in everything from iPhones to pacemakers – and replacing them with lithium-sulphur batteries.

Groundbreaking energy storage

Theoretically, lithiumsulfur batteries are capable of holding up to five-times more energy than lithiumion ones, but until now they have been wildly impractical for use in consumer electronics. The biggest challenge until now with lithium-sulphur batteries has been the instability of the cathode, which undergoes a 78% change in size each time it goes through a charge cycle.

This means the batteries degrade extremely quickly and do not last long enough for them to be recharged over and over again. Researchers at Monash University discovered that using a very flexible cathode allowed it to handle the expansion and contraction without significant degradation. In doing so, they claim to have created the “world’s most efficient” lithium-sulfur battery.

“The world needs radical new energy storage technologies to fight climate change. Lithium-sulphur batteries, which use extremely high-capacity sulphur, can store fivetimes as much capacity as traditional lithium-ion batteries, and are made from cheap materials that are available worldwide,” said Mahdokht Shaibani, who led the research.

Associate Professor Matthew Hill added: “This approach not only favours high performance metrics and long life cycle... it is also can lead to significant reductions in environmentally hazardous waste.” The research, which is published in Science Advances, could be a major milestone for the battery industry and could impact everything from consumer electronics to solar grids. Shaibani said the commercialisation of the batteries may be between two to four years away, and a patent for the manufacturing process has already been approved.
