Abstract
The invention is a method for preventing short circuiting in a lithium ion battery. The battery has an anode made of intercalation compound, a cathode made of an intercalation compound, and a separator having a thickness of 25 microns or less sandwiched between the anode and the cathode. The method includes the steps of rounding or beveling the edge portion of the cathode, so that during charging when the anode and cathode expand and squeeze the separator, the rounded or beveled edge portion of the cathode cannot cut the separator.
