You sure could, but no one ever will, at least not commercially, because the amount of money needed to buy a powerful, portable neutron source, plus a large enough supply of fissionable material, is outrageous. Not to mention that the majority of said items are exclusively sold to government labs, oilfield services, and the military. And, the risk of radioactive contamination and environmental exposure far outweigh any increase of power efficiency. I'm afraid that we're going to be stuck with the good old-fashioned chemical batteries for awhile.

Fission products are the fragments resulting from the fission of heavy nuclids during nuclear fission process
Currently, it can't. May be it could be in future.
nuclear fission
To sustain a fission chain reaction, each fission reaction must result in one more fission reaction. And that one should result in one more, and so on.
Fusion and fission are similar in that they both reduce mass and thereby release binding energy.
Fission and/or fusion.

There would not be enough fuel for that.

Covering a battery with a lemon will ruin the battery and will not make the appliance to which the battery is connected go faster.
you need to find a fission battery and give it to one of the rangers, or use it on the elevator if you have high enough repair. the rest is self-explanetory
hook a battery to it
