摘要： The present invention relates to a construction of an explosion-proof safety vent for small-size non-aqueous electrolyte batteries such as prismatic lithium-ion secondary batteries or with an oval cross section hence with a small area of seal plate, and to a method of producing a seal plate. It aims at securing safety of a battery by allowing an explosion-proof vent to operate without fail with a simple construction at no sacrifice of the capacity. In order to fulfill this aim, it provides an explosion-proof safety vent wherein upper peripheral edge of an opening of a bottomed cell container made of metal and the periphery of a seal plate made of metal are hermetically sealed by laser welding, a rivet serving as a terminal is inserted in a through hole provided on the central portion of the seal plate and hermetically fixed by crimping via a gasket, an exhaust hole is provided between the terminal and the periphery of the seal plate, and the exhaust hole is closed by a metal foil. With such a simple structure, it allows the vent to operate without fail to prevent accident and also proposes a method of continuously producing seal plates in the form of a hoop.

摘要： Heavy-load discharge characteristics of a primary battery are improved. Alternatively, the high-rate discharge characteristics of a secondary battery are improved. This is accomplished by employing manganese oxides as the positive active material on which a surface modified layer is formed. The surface modified layer consists of an oxide of at least one element selected from the group consisting of titanium, cobalt, nickel, strontium, lanthanum and its compound added mainly with a compound made of manganese oxide on the surface of manganese oxide powder consisting of manganese dioxide or a complex oxide of manganese and lithium. This is accomplished by using a solution of salt of at least one element selected from the group consisting of titanium, cobalt, nickel, strontium, and lanthanum to which a manganese salt and a solution, to which a solution of manganese salt are added.
