Aluminum-sulfur batteries

Unfortunately, one has to take all these battery "breakthroughs" with a ton of salt. In fact we hear about new battery tech pretty frequently nowadays.
However, researchers making it work in a lab is quite a different thing than large scale manufacturing, and making the battery safe enough to use for consumers and autos. This particular AL/S battery is quite a ways off, maybe 10-15 years or more from being able to be used in a vehicle (if ever).
The article also mentions that the normal operating temperature of this aluminum/sulfur battery is about the temperature of boiling water (212F/100C). This is a significant engineering challenge to adapt for use on a vehicle, along with all the safety issues of riding around on this boiling hot battery material.

On the other hand, Lithium Ion batteries work best at room temperatures, just like us.
Lithium Ion battery tech has the benefit of 40+ years of R+D and real world use, so there's no way any auto manufacturer is gong to be risking their reputation to change from lithium batteries any time soon.
Seems the biggest research right now with lithium batteries is learning how to replace the liquid electrolyte with a solid one, which will increase capacity, charging speed, and safety.
