Abstract

A manifold bi-cell assembly (20) for electrochemical cells such as a polymer lithium ion battery is provided along with a method of manufacture thereof. The disclosed electrochemical cell includes an elongated planar separator or substrate (26) formed of an elastic material. A plurality of discrete anodes (24) is positioned in longitudinally spaced apart relationship to one another and positioned between a pair of substrates to create a sandwich assembly wherein adjacent anodes have a substrate interface therebetween. A plurality of cathodes (28) corresponding in size, shape and number to the plurality of anodes is also positioned in longitudinally spaced apart relationship on an opposed side of the substrate in alignment with the anodes. The substrate is folded along its interfaces (30) to create a manifold assembly of alternately stacked anodes and cathodes.
