Is the lithium air battery over hyped?

I expect we shall know either way by 2030:

it probably is - but there is something attractive in the idea of connecting zillions of individual nanowire lithium batteries, like cells in a muscle tissue, to form a workable battery.

Over the years it's proved to be that all new battery developments are over-hyped. The majority never appear at all, and those that do often disappoint and sometimes have to be withdrawn for further development. That was true of NiMh for example, and the original cobalt cathode lithium batteries had to be replaced due to causing disastrous fires.

The history has made me a cynic about battery developments, but lead-acid and it's SLA derivative have performed well.
