Why do I get a semi-circle at higher frequency while performing impedance (200 kHz-.01 Hz) of graphite symmetric cell using blocking electrolyte?

I am doing potentiostatic impedance spectra of graphite symmetric cell in the frequency range of 200 kHz- .01Hz using blocking electrolyte. while the literature says that there must a 45°C line...
