1. The field flows from a positive electrode to the negative electrode. 2. Electrodeionization : Water is passed between a positive electrode and a negative electrode. 3. Most rechargeable batteries in portable electronics use lithium cobalt oxide for the positive electrode . 4. With a bias voltage " U ", electrons tunnel preferentially to the positive electrode . 5. So-called " deep cycle " batteries employ a different geometry for their positive electrodes . 6. The positive electrode is nickel hydroxide and the negative electrode is hydrogen ions or protons. 7. A typical cell has four main components : positive electrode , negative electrode, separator and electrolyte. 8. This makes the zinc rod the negative electrode and the copper rod the positive electrode . 9. Water is passed between an anode ( positive electrode ) and a cathode ( negative electrode ). 10. The positive electrode is made up of a dry sintered porous nickel plaque, which contains nickel hydroxide.
