I don't think Atomic batteries are used very often because of the concern of the results of them falling back to Earth in the event of some failure.
I referred to post#21: Curiosity is the first rover, powered by isotope battery. Inguenity, the helicopter transported with rover Persevance, ( also with isotope battery ) is powered by solar cells.
