Method for manufacturing lithium ion batteries

A method for manufacturing a multi-core lithium ion battery wherein the multi-core lithium ion battery (100) includes a sealed enclosure (116) and a support member (120) disposed within the sealed enclosure (116). The support member (120) includes a plurality of cavities (122) and a plurality of lithium ion core members (102) which are disposed the plurality of cavities (122). The lithium ion core members (122) are directly exposed to a shared atmosphere region (128) in the enclosure (116). The battery further includes a plurality of cavity liners (124), each of which is positioned between a corresponding one of the lithium ion core members (102) and a surface of a corresponding one of the cavities (122).
