This requires batteries which are very heavy. This is not a big problem in cars, but an absolute deal breaker in aircraft. The energy consumption of a plane scales roughly with the weight, which makes efficient battery powered flight pretty much impossible.

The mass problem in larger aircraft is mostly just an issue with landing AIUI.

One could imagine battery boosters jettisoned after supporting the climb to cruising altitude which autonomously return as drones to the airport.
