11. Chemically, bulk aluminium is a strongly high negative electrode potential. 12. A typical cell has four main components : positive electrode, negative electrode , separator and electrolyte. 13. The metal M in the negative electrode of a NiMH cell is an intermetallic compound. 14. The resulting ions are collected at a negative electrode . 15. This makes the zinc rod the negative electrode and the copper rod the positive electrode. 16. The positive electrode is nickel hydroxide and the negative electrode is hydrogen ions or protons. 17. The most commercially popular negative electrode is graphite. 18. In primary cells the positive and negative electrodes are known as the cathode and anode, respectively. 19. The undrilled main electrode is the negative electrode . 20. One unresolved issue is zinc build-up on the negative electrode that permeated the membrane, reducing efficiency.
