The stagnation of Li-ion batteries can be attributed to industry approaching the theoretical maximum energy density. So instead of optimizing the remaining 25%-30% capacity, focus shifted to Li-air or Li-S research. Li-S in particular can reach up to 2600 Wh/kg theoretical energy density, or 10x of current state of the art. Maybe you can shine some light on this, why do the search trends [1] for lithium sulfur appear so cyclic? I'm not aware of any uses in industry, or any major conferences/press cycles around Li-S.
