I had some CV and cycling test for my battery half-cells.

In the CV tests, they were reversible and performed very well.

But during the rate performance and the cycling test, they ran only at a low C-rate (0.1C and 0.2C). At 1C and 5C they did not work anymore.

I thought when the cells perform good in CV test, they also work well in cycling test.

Is it possible a result? Or did I sth wrong? (I did 3 times the experiment)
