Given an innovation of this sort,
there is not a single area of application, extending the range of electric cars.
You could also make lighter weight electric cars. Which would have their merits.
Think of the whole spectrum of EVs, lighter weight e-bikes, scooters, skateboards, or long range e-bikes. Electric aircraft start to become feasible.
Much more flight time out of your toy drone, multi-day battery life for your phone or laptop.
Energy storage in off grid setups becomes simpler, or more capacity in the same space.
Etc. etc.
All that provided this new design could function as a more or less slot in replacement, or better, for current lithium batteries in terms of manufacturing, cost, and what not.
