Abstract: Provided is a secondary battery comprising a core (7), tabs (4) protruding from an end of the core (7), a tab lead-out device placed at the end of the core (7), and a cover plate (1). The tab lead-out device includes an insulating layer (6) adjacent to the end of the core (7) and a conductive layer (5) distant from the end of the core (7). The tabs (4) are electrically connected to the conductive layer (5). The conductive layer (5) is electrically connected to the cover plate (1). The secondary battery further comprises a connector and a pad (3) stacked between the conductive layer (5) of the tab lead-out device and the cover plate (1). The tabs (4) are compacted between the pad (3) and the conductive layer (5) of the tab lead-out device by the connector.

Abstract: The invention is a three-way catalyst, its method of manufacture, and use for treating exhaust gas generated by a gasoline internal combustion engine. The method comprises coating a substrate with mixed metal oxide particles in an amount of 10-30 wt. % based on the weight of the substrate. The mixed metal oxide comprises at least aluminum and rare earth metals of cerium and lanthanum. Precious metals are then deposited on the oxide coating and comprise at least one of platinum and palladium overcoated with rhodium. The total loading of precious metals is about 5-35 g/ft3 of the substrate.
