What higher-density batteries change for submarines and drones

Better batteries extend drone endurance and give submarines safer emergency options, but they do not eliminate the need for a source of charging power.

Question

How will increasing battery power density affect submarines and underwater drones?

Short answer

It will improve endurance and emergency capability, though submarines still need a primary source to recharge the batteries.

Notes

An underwater drone can return to a submarine to recharge, while the parent boat must still generate the electricity. Higher density extends useful endurance but does not remove that energy source from the system. For a nuclear submarine, a larger battery reserve could be decisive after a reactor shutdown by preserving enough propulsion and services to reach the surface. The technology therefore improves resilience as well as submerged endurance.
