1. A method of designing a thin film battery device and manufacturing the thin film battery device by determining at least one material property of at least one component of an electrochemical system using a process to reduce a difference of a performance characteristic between a numerical simulation result of a physical model and an empirical result, the method comprising:

  • providing an electrochemical cell using a thin film process;

    performing a plurality of tests on the electrochemical cell, using a processor, to identify one or more target performance characteristics of the electrochemical cell, the plurality of tests including respective operational modes of the electrochemical cell;

    deriving a plurality of performance characteristics from the plurality of tests to provide a performance database, the performance database comprising the operational modes and the respective performance characteristics;

    performing a surrogate based analysis process;

    determining a plurality of outputs of the surrogate based analysis function; and

    determining a value of the unknown material property.
