No. The big challenge for lithium metal batteries (and every other battery research project) is, has always been, and always will be, manufacturability.
Five or six years ago I contemplated starting a satirical blog, "Revolutionary Battery Chemistry of the Week", modelled after the "Dinosaur Fossil of the Week" blog, which sadly seems to have disappeared.
Since then, thousands of "breakthrough", "revolutionary" battery chemistries have been announced. Yet, somehow, actual in-use batteries are based on incremental improvements to Li-NMC and LiFePO4 chemistries. A primary reason is manufacturability.
