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?????????
