Abstract

A manifold bi-cell assembly 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 elongate planar separator or substrate formed of an elastic material. A plurality of discrete anodes with laterally offset leads 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 with laterally offset leads corresponding in size, shape and number to the plurality of anodes is also positioned in longitudinal spaced apart relation on an opposed side of said substrate and overlying the anodes. The substrate is folded along its interfaces to create a manifold assembly wherein the anodes and cathodes are superimposed in a stacked configuration with the leads of the cathodes being offset from the leads of the anodes.
