摘 要：
PURPOSE:To enhance the cycle property and reliability of a lithium secondary battery by performing a treatment using surface active agent only at that portion of a separator which is in direct touch with a positive electrode plate or negative
electrode plate so as to provide retaining property. CONSTITUTION:A portion which has retaining property for
electrolyte and a portion which does not have that property are provided in a separator 3, and the portion with the
retaining property is disposed on that face of the separator 3 which is in direct touch with a positive electrode plate 1 or negative electrode plate 2. Dendrite-shaped lithium is thereby prevented from shifting to the upper and lower portions of

a group and from accumulating there. The dendrite-shaped lithium is prevented from shifting to the upper and lower portions of the group and from accumulating there also by heating the portion of the separator other than its face in direct contact with the positive or negative
electrode plate, and by blocking holes by means of the thermal contraction so as to lose the liquid retaining property. 主权项：
