NOVELTY - The battery has a positive electrode (30) that is provided with positive electrode active substance (110) arranged with hollow structure. The positive electrode is provided with hollow portion formed inside shell portion. A heat-resistant layer (51) is arranged between positive electrode and negative electrode (40), and provided with plate-shaped inorganic filler particles (52) as main component. The ratio of average particle diameter of inorganic filler particles relative to particle diameter of particles of positive electrode active substance is 0.5 or higher.    USE - Non-aqueous electrolyte secondary battery such as lithium secondary battery mounted in vehicle (claimed) such as car, electric vehicle (EV), hybrid vehicle (HV), plug-in hybrid vehicle (PHV) and fuel cell vehicle, for use as driving power source. Can also be used in personal computer, and hand-held device.    ADVANTAGE - The heat-resistant layer with inorganic filler such as alumina is provided between positive and negative electrodes to improve heat resistance, so as to effectively prevent portion of positive electrode active substance that detaches from reaching the negative electrode during overcharging. Thus, the leakage current can be suppressed during overcharging and thermal stability of battery in overcharged state can be improved efficiently. The strength of heat-resistant layer can be increased effectively. Since the plate-shaped inorganic filler particles inhibit primary particles detached from secondary particles of positive electrode active substance from reaching negative electrode, the quantity of heat generated in battery following shut down can be suppressed and excellent thermal stability of battery can be achieved effectively. The performance of battery can be improved efficiently.
