I guess it depends on what is included and/or excluded to get X-Joules of electrical energy output ... and what types of 'batteries' you want to compare it to.

I can think of some possibilities for an atomic battery to be net 'cleaner'... depending on the list of included / excluded.
For one such example:
- A modern one can put out around ~140 Mwh of electrical energy over ~263 years from ~1kg of Pu238 +33kg of device... It will have __ dirty/waste in it's production.
- If I include all the dirty/waste of production of the many many Graphene batteries needed to get the same ~140Mwh electrical output... either one giant battery cycled many times ... or many smaller ones cycled many times.
- This is already included for the Initial Atomic's production waste.
- If I include all the dirty/waste of energy production with which to charge charge those Graphene batteries to get ~140Mwh of electrical output.
- This is already included for the initial Atomic's production waste.
- If I include all the dirty/waste production of the electronics needed for Graphene Battery Input & Output ... charger , electronics to ensure not over discharged ... etc.
- This is already included as part of the initial Atomic's production waste.
- If I include the disposal waste of all those worn out Graphene batteries, electronics, etc ... compared to the disposal waste of the worn out Atomic.
That creates a fairly tall order for the Graphene battery.

Especially considering ... that whether you use it in the Atomic battery or not ... the Pu238 is going to do it's half life and it is going to emit the radiation ... convert it to electrical energy and contain and reduce the harmful radiation emitted with an Atomic cell ... or spread out that same initial radiation ( more net radiation output ) over a larger geographic area , and don't make use of that energy at all.

Electric Eels could also be considered a fairly net 'clean' ... 'battery'... if you wanted to include them.
