<p><P>PROBLEM TO BE SOLVED: To provide a separator for batteries which can manufacture batteries with a high production yield and a high capacity without occurrence of short-circuiting between adjacent electrodes, which is caused when burrs on electrode plates stick through a separator while a group of electrode plates are produced, and without occurrence of tearing a separator by the edges of an electrode plate even if the separator is as thin as not more than 100μm in thickness, and also to provide a battery using the same. <P>SOLUTION: This separator for batteries includes a high strength polyethylene fiber having an tensile strength of 20 cN/dtex or more and a very thin fiber having an average diameter of 5μm or less, and comprises a non-woven fabric which is formed from the high strength polyethylene fiber in a fusion state by being melted itself. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
