Graphite!!

I would like to know where I can get/buy graphite for electrolysis. Does the purity affect the conductivity? If yes, better not telling me to get graphite from pencils because they are not pure. THX!!

✔ 最佳答案

you can get graphite rods by cutting open used zinc-carbon cells (the commonest and cheapest cylindrical dry cells, not alkaline cells) and taking out the graphite rods inside. The positive pole of zinc-carbon cell is made of graphite rod. If you are rich enough, you may use new cells.

你可以把用過的鋅碳電池（即最常見最便宜的圓柱體乾電池，切不可用鹼性電池）打開，取出其中的石墨棒。鋅碳電池的正極是用石墨棒製成的。若果你有足夠金錢，你可以用新的電池。

鋅碳電池，普通人稱為『碳性電芯』。
