We will literally have silicon anodes batteries in 2-3 years, we will have pure lithium anodes in 4-5 years, after that we will have sulfer-lithium batteries within the decade. With lithium annodes we are at a point where you can replace most air-travel with battery planes. There is way more upside for improvement in batteries compared to fuel cells. Fuel cells have no future in transportation unless there is some fundamental breakthrew that nobody can anticipate, nothing I have seen even in research improves fuel cell technology enough to make it viable.
