    Abstract: An electrode comprising a cast-film architecture wherein a silicon-based polymer precursor is cast on to a current collector directly from the liquid, and processed in-situ to create a high performance anode for lithium ion batteries. In this in-situ process the liquid polymer is cross-linked and pyrolyzed to create a cast-film-anode architecture. The cast-film architecture is distinctly different from the conventional powder-based ex-situ process whereby the polymer precursor is made into powders by a ex-situ process; with these powders being then combined with conducting agents and binders to create a paste which is screen printed on a current collector to produce electrode with a powder-anode architecture. The cast-film architecture obviates the need for conducting agents and binders, simplifying the production process for the anode, without a loss in performance. The energy capacity per unit volume of the anode material is two to ten times greater for the cast architecture.
