it doesn't typically. but carbon does have an electrode potential [remember zinc carbon batteries?] so it /could/ happen. i'd take my chances on carbon though before i'd take my chances of steel and any other bike metal.

Actually, a "zinc carbon" cell has an outer steel protective shell, a cardboard insulator sleeve, a inner zinc shell [1] that also serves as the anode, a permeable paper separator inside the shell, and a natural manganese oxide powder cathode saturated with zinc

maybe at rayovac, but other places, and i've recently dissected such an example from china, they use a simple back-extruded zinc bucket as the anode and a simple carbon rod as the cathode. just a paper shell on the exterior too. quite extraordinarily crude.


and ammonium chloride electrolytes with a carbon (graphite) collector rod in the middle. Some additional carbon (graphite) is added to the cathode powder to improve conductivity. The reaction between the anode and cathode could take place without the carbon being added to the cathode.

Not only do I remember these type of batteries, but assembled quite a few prototypes by hand when I worked for Rayovac in the R&D department.

worthy!



[1] Which is why these batteries usually leak after being discharged, since perforations develop in the anode shell.


indeed they do. horrible things.
