I don't know of any research on the topic,
but common sense seems to me to suggest you are wrong.
Suppose a rechargeable battery can be re-charged 100 times
and holds 1/2 the charge of a non-rechargeable.
Then you would be saying that for some reason
50 non-rechargable batteries require less re-cycling
than 1 rechargeable.
I'm sure the electricity used in re-charging is negligible,
as also is the energy cost of the charger.
(And unless you religiously avoid rechargeables
you will require a charger in any case.)
