The technology has been around for awhile (from the 1960s). Wiki talks about their problems. An abstract shows:

Lithium/sulfur (Li/S) battery has a 3–5 fold higher theoretical energy density than state-of-art lithium-ion batteries, and research has been ongoing for more than three decades. However, the commercialization of Li/S battery still cannot be realized due to many problematic issues, including short cycle life, low cycling efficiency, poor safety and a high self-discharge rate. All these issues are related to the dissolution of lithium polysulfide (PS), the series of sulfur reduction intermediates, in liquid electrolyte and to resulting parasitic reactions with the lithium anode and electrolyte components. On the other hand, the dissolution of PS is essential for the performance of a Li/S cell. Without dissolution of PS, the Li/S cell cannot operate progressively due to the non-conductive nature of elemental sulfur and its reduction products. In this review article, we start with the fundamental chemistry of elemental sulfur in order to discuss the problems and solutions of liquid electrolyte Li/S battery.

Don’t solid state lithium-sodium batteries also have large potential. Not to mention that UT is leading the effort to build them thru 2 professors: goodenough and braga.

Yep, solid state will be the game changer. Lithium sulfur batteries are only good for about 200 cycles.

Same. 

 

Edit:  I should have realized that every other motherfucker on Surly would home in on this and not posted it without reading the thread.
