PURPOSE: To prevent the deterioration of the discharge characteristic at the high slewing, by arranging a leakage-proof ring made of inorganic substance between the pellet made of a plurality of electrolytic rings and the depolarization agent arranged concentrically.
CONSTITUTION: The cell element of the thermo-cell is formed of a negative pole current collector 1, negative pole active substance 2, inner protective ring 3, outer protective ring 4, positive pole current collector 12 and a plurality of DEB pellets 5∼8 integrated with ring-shaped EB layer 10 and DE layer 11, and the leak-proof ring 9 arranged between them. When forming the leak-proof ring 9 with an inorganic binder to be used for DEB pellets 5∼8 and the asbestos paper using the inner and outer protective rings 3, 4, the leakage of the thermo- cell when using in a rocket and performing the high slewing can be reduced considerably resulting in the enlargement of the usage.
