Abstract
The object of the present invention is to obtain an electrode whose resistivity increases with temperature, and a battery using the same. Specifically, the invention consists in limiting the proportion of a conductive filler contained in electron conductive particles of an electron conductive particle layer to a range of from 55 to 70 parts by weight. A battery constituted by using the electrode has an increased discharge capacity and is capable of reducing a short-circuit current.
