CELL AND METHOD OF PRODUCING THE SAME

摘要

In a conventional battery containing metal lithium in the negative electrode, there is a problem that large short-circuit current was generated with temperature rise due to internal short-circuit or the like, and therefore, the temperature of the battery further increases due to exothermic reaction to increase the short-circuit current. The present invention has been carried out in order to solve the above problems. The battery of the present invention comprises a negative electrode 2 containing lithium metal, a positive electrode 1 containing a positive electrode active material 8 and an electronically conductive material 9 contacted to the positive electrode active material 8, and an electrolytic layer 3 between the positive electrode 1 and the negative electrode 2, wherein the electronically conductive material 9 comprises an electrically conductive filler and a resin and resistance thereof is increased with temperature rise.
