Is this what i think it is? Answered

i was taking apart a heavy duty panosonic battery. it didn't say if it was dry cell or not. when i opend it up. and it only had this black powder. it was kind of lumpy. i think its magnesium dioxide. there was also i rod. i took it out and washed it. it is black. i think its a carbon rod since the inside of the battery wasnt wet. it looks like it has little pores on the surface. SO my question is..... is the rod carbon?????????

Manganese dioxide (MnO2), NOT magnesium dioxide, BTW. And some other things, usually.

probably, I think the powder is zinc. Glad to see that you follow my advice ;)
