ABSTRACT:
Spirally-rolled electrodes for batteries wherein the electrodes having a concentric circle shape or an elliptic shape with positive electrode and negative electrode wound spirally via a separator therebetween has the characteristics as below:(1) the positive electrode and/or negative electrode consist of the combinations of several electrode plates;(2) each of the combinations in the positive electrode and/or the negative electrode so includes that the total amount of the active material or pseudo-active material which are the main materials for the electrode is substantially constant and;(3) each electrode plate in the electrode including plural electrodes is wound in series with an interval therebetween.
