PROBLEM TO BE SOLVED: To increase the holding force of a metal active material, accelerate the electrochemical reaction of the active material and an electrolyte, reduce the internal resistance of a battery, and allow a quick charge/discharge by kneading the metal active material into the fibered metal of a fine wire-like random-orientation aggregate, and forming a plate-like body with the prescribed thickness. SOLUTION: This electrode 1 is provided with a fibered metal 3 and a metal active material 4, and the fibered metal 3 is formed as a fine wire-like random- orientation aggregate. Lead is gelatinized by dilute sulfuric acid as the metal active material 4 for a negative electrode, for example, and it is kneaded between the constituting metal fibers of the fibered metal 3 under pressure. The metal active material 4 entering complicated intervals can be firmly held by the complex shape of the fibered metal of the random-orientation aggregate constituting the electrode 1 and mutual entangling. When powdery activated carbon is mixed in the metal active material 4 constituting the electrode 1, the surface area is increased, the electrochemical reaction of the metal active material 4 and an electrolyte is accelerated, and a quick charging/discharing can be made. |
