摘要:
The battery of the present invention comprises the electrode which contains the pre-determined amount of electronically conductive material at which resistance increases in accordance with temperature rise and conductive agent; the electrode wherein the ratio of the total amount of the electronically conductive material and the conductive agent to the active material is set to a pre-determined value; and the electrode wherein the average particle size of the conductive agent based on the average particle size of the electronically conductive material is in a pre-determined range. The coducitive material contains an electrically conductive filler and a crystalline resin. The conductive material and the coductive agent are contacted with the active material. A significant reduction in short circuit current is achieved over a defined range of conductive agent particle size.
