It's true that drones have rather specific lithium batteries - the foils are thicker so the batteries can be charged and discharged faster than eg. mobile phone batteries. However, any lithium battery plant could, within a matter of days, be reconfigured to make drone-suitable batteries. Also, currently drones use a tiny proportion of the worlds battery production capacity. EV's and consumer electronics use vastly more. This capacity could easily be redirected. So attacking the battery production capacity as a way to limit the enemies drone production doesn't seem like the smart move.
