Why is Voltage decreasing with increasing charge(positive current 0.1C rate) in galvanostatic charge discharge testing (see picture attached)?

I have done OCV check (2.9V approx vs Li which is ok). During first charging/discharge cycle in Galvanostatic charge discharge test of a lab made li ion cell, I found that always voltage...

For Li Ion Batteries, if we keep anode and cathode equal (for coin or Swagelok type cell) how to over come mismatch problem(check description)?

I know separator should be largest. How to select andoe and cathode size. I studied that if we keep them equal and if there occurs slight mismatch it will be a problem (Li plating or less...
