description Conventional batteries have a problem that, in case the battery temperature should rise to 100 DEG C or higher due to an internal short-circuit, etc., a large short-circuit current develops to generate heat. It follows that the battery temperature further increases, which can result in a further increase of the short-circuit current. Further, some of electrode structures involve reduction in discharge capacity. These problems are solved by a battery in which an electron conductive material (9), being in contact with an active material (8) in an electrode, comprises a conductive filler and a resin so that the electrode may increase its resistivity with a temperature rise, and the ratio of the particle size of the electron conductive material (9) to that of the active material (8) is in a range of from 0.1 to 20.
