Abstract:
A cover assembly for a Lithium-ion battery container to improve the durability of the battery. A high pressure injection molded polymer is combined with flanges disposed on the current collecting posts of the battery to provide an improved seal for the battery cover, especially at the interface of the cover and the current collecting posts. The injection molded polymer is fused to the flanges, current collecting posts and container cover to result in a diffusion path of increased length for gases and/or liquids which are known to enter or escape from battery containers. Additional polymer layers can be applied to the assembly to further improve the seal.
Abstract:
A stacked microelectronic assembly is provided which includes first and second stacked microelectronic elements (101, 102). Each of the first and second microelectronic elements can include a conductive layer (610) extending along a face (608) of such microelectronic element. At least one of the first and second microelectronic elements can include a recess (618) extending from the rear surface towards the front surface, and a conductive via (605) extending from the recess through the bond pad (603) and electrically connected to the bond pad, with a conductive layer (610) connected to the via and extending along a rear face (608) of the microelectronic element (101, 102) towards an edge (620) of the microelectronic element. A plurality of leads (224) can extend from the conductive layers (610) of the first and second microelectronic elements and a plurality of terminals (616) of the assembly can be electrically connected with the leads.
