1. A method of making an electrochromic (EC) device, comprising:
providing a light transmissive first substrate;
providing a precursor mixture comprising an oxygen-containing lithium salt, a halogen salt of lithium, and tungsten oxide nanoparticles, and a solvent on the first substrate;
annealing the precursor mixture to form a working electrode on the first substrate;
providing a light transmissive second substrate;
forming a counter electrode on the second substrate; and
forming a solid state electrolyte including a polymer material between the counter electrode and the working electrode.
