Lithium-sulfur batteries look like the most possible candidate as the next incremental evolution of the lithium ion batteries.
Lithium metal... not so much.
But I really hope for revolution in this space, rather than incremental changes. This will boost and give wings to so many other inventions.
- marcosdumay 10y agoLithium-sulfur only works hot. It may be a great option for huge batteries connected to the power grid, but plugging a 200°C inflammable battery to your laptop might not increase its safety.
- alex_hirner 10y agoYou must be talking about the flow version of lithium-sulfur. The ones with (presumably) graphite and cobalt oxide electrodes are going into e-scooters in China now [0]. However, they are yet far from the theoretical 2x in volumetric density of lithium-ion. For a very good survey on the state of the art in lithium-sulfur look up this recent study [1].
