I know what cathodic protection is. It's the Engrish way of saying "circuit protection". The cathode is the (+) end of a conventional alkaline battery. The other end is the anode.

The "block" refers to shutting off the battery when the voltage drops to a certain level, typically around 3.2 volts, or above 4.2 volts.

On a side note, IMRs don't corrode like regular carbon and alkaline batteries. The stuff they're made of (LiMn2O4) is more stable and less corrosive than the electrolyte material in alkalines. Plus, the casings on IMRs are typically higher quality than grocery store batteries.
