I am not sure that I understand the question, but AM (MW) and SW battery operated vacuum tube sets are quite common. The early tube radios, offered in the '20s were battery operated, but usually not portable. AC powered sets were introduced in the mid '20s.

I have a few '20s sets in my collection, and a fair number of battery operated tube portables produced in the '30s through the '50s, before transistor sets became available. "Farm radios" were also produced, these looked like "normal" ac powered (not portable) sets, but were designed to run on batteries, or 32 Volt DC power, that was sometimes generated by windmills in rural areas, before AC became available.

FM is another matter... except for a few 1 tube regenerative sets, I have not seen battery powered tube FMs.
