RECHARGEABLE POSITIVE PLATE Russian patent published in 1999 - IPC

FIELD: rechargeable power supplies using active sulfur in power plate. SUBSTANCE: positive plate has mixture of 20-80 mass percent of active sulfur, 5-40 mass percent of electron conductor, and 15-75 mass percent of ion conductor. Battery cell using mentioned positive plate has also negative plate and electrolyte separator. Negative plate may contain carbon, carbon-saturated lithium or sodium, or carbon mixed up with lithium or sodium., Positive plate manufacturing process involves homogenization of mixture of active sulfur, electron and ion conductors, plate shaping from homogeneous mass, drying, and deposition of plate onto current collector. EFFECT: reduced operating temperature and improved specific power characteristics. 47 cl, 14 dwg, 21 ex
