<P>PROBLEM TO BE SOLVED: To provide an all solid secondary battery in which a short circuit phenomenon is not brought about by the contamination of positive electrode and negative electrode active material particles separated from a positive electrode and a negative electrode at the surrounding (end face) of an electrolyte layer interposed between a pair of electrodes, which is liable to occur at the time of manufacturing the all solid secondary battery. <P>SOLUTION: The all solid lithium secondary battery is a battery element which is provided with a positive electrode 1 and a negative electrode 7, a lithium ion conductive solid electrolyte layer 13 installed between the positive electrode 1 and the negative electrode 7, and lead plates which are connected individually to the positive electrode and the negative electrode, respectively, and has the lithium ion conductive solid electrolyte layer 13 of a shape covering at least either of the electrode of the positive electrode 1 and the negative electrode 7, and the lead plates of the positive electrode 1 and the negative electrode 7 have shapes equivalent to or larger than the lithium ion conductive solid electrolyte layer 13. <P>COPYRIGHT: (C)2009,JPO&INPIT |
