Is there a formula for "Drive Strength" of a cell? Or atleast may I know on what all physical attributes of a cell the drive strength depends on?

Thanks in advance!
 

Cell "strength" might be considered as as State of CHarge and Effective Series Resistance (ESR). ESR rises as SOC drops near end of charge and also ESR rises with age or gets "weaker"

Each battery chemistry and supplier quality has its own "strength" model

Generally Drive Current will be limited by SOC, Ah capacity and ESR from the Datasheets.

Besides "Size" a more detailed answer would get into laws of "Physical Chemistry"
