An “Expansion-Tolerant” Architecture offers stability to ultra-high capacity Lithium-Sulfur battery
A lithium sulfur battery that has four times the capacity than existing electric car batteries has been built and tested by researchers at Monash University, revealed in a paper published in Science Advances.
This would allow you to drive Melbourne to Sydney with
just one charge – driving the coastal route. A current edition prius would
require to stop in Albury-Wodonga to recharge.
Widespread adoption of electric cars in New South Wales would increase demand on the power grid by an average of eight per cent, according to new research from the School of Engineering.
Sohaib Rafique and Professor Graham Town used data from the New South Wales Household Travel Survey to determine the demand that electric cars would place on the grid if they were used in 82 per cent of weekday and 81 per cent of weekend commutes, with trips less than 35km in length.

Lithium batteries have transformed power storage—from smartphones to electric cars and submarines. But like every battery their chemical composition changes through every charge cycle.
Lithium ions sitting in layers of graphite move between electrodes and change the oxidation state of, magnesium oxide, for example. The chemical rearrangements cause the graphite and oxide layers to physically expand and contract by up to 15 per cent at every cycle, cracking and detaching from the electrodes.
