Scientists in China have demonstrated a wireless power transmission system that uses a ground-based microwave emitter to beam energy to an antenna array mounted on the aircraft’s underside. Importantly, they were able to do this while both the drone and charging system were in motion.

In tests, the car-mounted system kept fixed-wing drones in the air for up to 3.1 hours at an altitude of 15 metres (49 feet). The key challenge that the team overcame was maintaining alignment between the emitter and the drone during flight, wrote Song Liwei, the project’s leader.

I think that the "recharging" will always be a vulnerable stage and that the objective is to do that puntually and not a continuous dependence on power supply, but still seems safer and easier to abort than the one done currently with non electric planes, and for defense patrolling you will have more important infrastructures that would be targeted first, I still see only advantages if mature enough

For an electric recharge I think you need a decent size infrastucture that you cannot move that much or easily. I don't think that you can do with a enourmous power bank mounted on a truck.

but still seems safer and easier to abort than the one done currently with non electric planes,

Except that you can refuel a normal plane with just a couple of trucks and a strip of road long enough (Sweden built the Viggen around this principle and even the US has the highway designed to work as temporary airfield by some old law).
While it is easy to hit an airport, it became a lot harder to take out all the roads (in part because you will later need them)

and for defense patrolling you will have more important infrastructures that would be targeted first, I still see only advantages if mature enough

Yes, the charging station. Once I take out it, you electric planes are out of order. No more patrolling.
