絡を防止していた。Conventional technology When constructing a spiral electrode group for an alkaline storage battery, the electrodes are wound with a small radius of curvature near the beginning of the winding, which contacts the winding core, which causes cracks to occur on the outer peripheral surface of the electrodes, causing short circuits. For this reason, as in Japanese Patent Publication No. 57-5026, an auxiliary separator 4 made of the same material as the main separator 3 is used at the beginning of winding of either or both of the positive and negative electrode plates 1 and 2 to prevent short circuits. .

。Problems to be Solved by the Invention However, since the tension of the group increases, a lot of time is required for the process of injecting the electrolyte into the electrode group. In addition, in order to improve liquid absorption performance, there was a method in which the separator was rolled into a funnel shape by shifting the separator (Utility Model Application Publication No. 69-178866), and a method in which a surfactant was added to the separator, but this method required a lot of man-hours to configure the group. However, there were problems such as the amount of man-hours required to process the separator. Furthermore, when the main separator and the auxiliary separator are changed to hydrophilic materials, the liquid absorption performance is improved, but the alkali resistance is insufficient, resulting in a problem of reduced life performance.
この様な従来の構成ではセパレータが電解液を吸収する
速度が遅いため電極表面に電解液が到達せず注液に長時
間を要するという問題点があった。Such a conventional configuration has the problem that the rate at which the separator absorbs the electrolyte is slow, so that the electrolyte does not reach the electrode surface and it takes a long time to inject the electrolyte.
本発明はこの様な問題点を解決することを目的とする。The present invention aims to solve these problems.

る。Means for Solving the Problems The present invention uses band-shaped positive and negative poles and separators, and in a spiral type electrode plate group in which the poles are separated by the separators and the whole is wound in a spiral, the winding start point of either the positive or negative pole is used. The edge is covered with an auxiliary separator made of a highly hydrophilic material, which is separate from the main separator that completely covers and isolates the other electrode, and is wound together with the main separator.
