Lithium-Sulfur batteries?

This looks pretty promising:

Already, lithium-sulfur (Li-S) batteries have the potential to store two-to-five times as much energy by weight than the current generation of lithium-ion batteries, which has offered great promise for the storage of renewable energy and for longer-range electric vehicles, in particular.

What has been standing in the way of their adoption, however, has been the fact that the electrodes in lithium-sulfur batteries tended to deteriorate rapidly, causing the batteries to break down.

According to the study by the Monash research team, led by Professor Matthew Hill, Dr Mahdokht Shaibani and Professor Mainak Majumber, the new interlayer delivers high capacity and long-life.

Essentially, the discovery enables the charge and discharge of batteries and discharge of energy at a much faster rate than previously offered. For an EV, the team says this breakthrough could mean only needing to re-charge once a week.
