Summary:A sealed nonaqueous electrolyte secondary battery having a case which is deformed when the inner pressure is increased is characterized in that a material capable of occluding and releasing lithium is used as a negative electrode material, and a mixture of a lithium transition metal composite oxide containing Ni and Mn as transition metals and having a layered structure and a lithium cobaltate is used as a positive electrode material. L'invention concerne un accumulateur d'électrolyte non aqueux hermétique doté d'un logement qui est déformé lorsque la pression interne augmente et qui se caractérise par le fait qu'un matériau capable de fermer et de libérer du lithium est utilisé en tant que matériau d'électrode négative, et un mélange d'un oxyde composite de métal de transition de lithium contenant Ni et Mn en tant que métaux de transition et présentant une structure en couches et un cobaltate de lithium est utilisé en tant que matériau d'électrode positive.
