   You can certainly compress CO2 to make it into quite a dense fluid.   
      
   Getting that fluid to conduct electricity seems to be difficult.   
      
   The aim would be to get oxygen diffusing out of one electrode and carbon   
   - presumably graphite - depositing on the other.   
      
   A less ambitious target would be to get carbon monoxide at one electrode   
   and oxygen at the other   
      
   My guess would be that it is hopeless.
