31. Since zinc is electroplated during charge at the negative electrode this system is classified as a hybrid flow battery. 32. Cathode rays are so named because they are emitted by the negative electrode , or cathode, in a vacuum tube. 33. Use of highly reactive lithium as a negative electrode causes dissociation of most of the commonly used other type electrolytes. 34. During normal lead-acid battery operation, lead sulfate crystals grow on the negative electrode during discharging and dissolve again during charging. 35. Does the negative electrode of a capacitor gain mass when charged ? anonymous6494 02 : 47, 2 October 2007 ( UTC) 36. The positive and negative electrode plates, isolated from each other by the separator, are rolled in a spiral shape inside the case. 37. In some literature, the terms " anode " and " cathode " are used in place of negative electrode and positive electrode. 38. Physically, UltraBattery has a single positive electrode and a twin negative electrode one part carbon, one part lead, in a common electrolyte. 39. Yasunaga has commented that the life is expected to be even longer when the negative electrodes get the same technology applied to them. 40. In rechargeable cells the positive electrode is the cathode on discharge and the anode on charge, and vice versa for the negative electrode .
