Claim Text:
1. A method for forming an electrochemical cell in situ from a nanocomposite which enables self-assembly of a tri-layer electrochemical cell, comprising the steps of: supplying an ionically conductive, electrically insulative single-layer nanocomposite between two current collectors at an initial voltage of 0 V, wherein the nanocomposite has an ionic conductivity greater than 0.0001 mS/cm and includes a binder and a metal halide having a metal cation and a halide anion; and applying a potential across the nanocomposite by way of the two current collectors, thereby forming in situ the tri-layer electrochemical cell comprising: (i) a negative electrode comprising an elemental metal formed by reducing the metal cation; (ii) a positive electrode comprising an oxidized form of the halide anion; and (iii) a thermodynamically stable electrolyte comprising the metal halide.
